Why didn't I think of that - I've had this tank for almost a year I've only used blue and white, white during the day and blue all night as a nightligh. LOL.
dennis gall it amazed me that they know the red light means food now. Train yours with a colour. The reason I thought of it was some fish didn’t realise food had been dropped in, and then miss feeding I thought there must be something to let them know it’s feeding so I tried it. It took a few times but not long
Be careful if you fill it completely. The top has a dome area in the middle back to allow cords and airlines to be brought in. If it is completely full the fish can swim into the filter area and then to the intake chamber or pump chamber. As the water level drops they become trapped in the back. I have found both fish and snails in the pump side several times.
This is by far my favorite tank I own. Sure, people have massive 15000 gallon reef tanks, and 200 gallon Cichlid tanks, but the look and simplicity of the flex makes it so cool.
My Fluval Flex was just delivered a couple days ago and I was looking for aquascape inspiration. I'm so very glad I came across your video. I also watched several others, including the mods you made. As I'd like to keep shrimp for the first time, I really appreciate the info on using sponges on the big filter intakes. That could've been a costly mistake for me. Your plant recommendations are spot on and helped me with my ordering. Thank you so much for this. I'm now a subscriber and probably a fan for life. In the past, I've had as many as 20 tanks going, from 220g to 5g. I'm just now getting back into it and the new products on the market are amazing. I appreciate you breaking them down for me! Cheers!
Recently purchased this for my son for his birthday. I watched this video just before setting it up and it was the perfect thing to make me feel like I knew what I was doing :)
looks like it woud be easy to add additional strip LED DIY style in that lid at least. I have one of these sitting in my basement as well. i actually don't like the honeycombing, interrupts scaping a bit depending on what youa re doing. Looking forward to seeing how this does in time.
+Rachel O'leary I was thinking the same thing about the lights. The frosted tops on the other tanks they do it a bit nicer. I noticed it seems to block the light a little too when your closer to eye level. So I wonder if that was part of the decision to put it around the top instead of just the filter part like the specs. I'd be interested to hear what ideas you have for all that space in the filter area.
pecktec I've been watching your channel for a few years. I'm so happy you have this aquarium from Fluval to do an unboxing and review on. Ever since Fluval announced it I've been curious because of it's unique shape. I had a Fluval Edge, but sold it due to the limitations in working/maintenance space based on the access port on the tank. I watch a lot of unboxing, review, aquascaping, and stocking videos here on youtube and I have found yours to be one of a couple of the highest calibre. I appreciate you sharing your time with us all as well as your knowledge and passion for the hobby. Honestly, I was so excited to see a Fluval Flex video from you! I'll be curious to see update videos and further reviews of the Fluval Flex from you before I decide ultimately to purchase one. Thank you again!!
oh you are most welcome! I also really enjoy your aqua scaping and I love the jungle in the 27 gallon cube I believe it is. In your updates that is one of my favourites and also the monte carlo carpeting in your kitchen Spec V. I'm curious to see how live plants do in the spec as when I get one I'd like to have live plants and try the monte carlo. It's been a few years since I've had an aquarium. I do have one question, with the ADA amazonian aqua soil is it the regular size or the smaller "powder" size recommended for nano tanks in your fluval Spec V? Thanks!!!
I have to say, even though at this time I don't have the time anymore for tanks. I always found more relaxation and enjoyment in the actual setting up of them and building wet/dry filters. So these videos allowed me that zen time without the hassles or debt :-) Thanks for posting them! It was time well spent watching an empty tank transform.
Cool new tank design, I'm looking for a new tank and this may work with the stand I just got. The stand was originally built to display art and is small by sturdy, so I think it will hold the 15 gallon - depending on dimensions. I love dragon stone - you just can't go wrong with it. My favorite line was "If you want to give your fish a seizure" exactly my thought when I saw it. The "Bold curve design" was pretty funny too. Great video!
Thanks, man for this video. I have been watching your channel for a while but this was the very first of your episodes that I watched. I just bought this tank for my bedroom. You've inspired me. I appreciate what you do!
I've been watching videos and looking at all the Fluval tanks since the Edge came out. Flex seems way easier to maintain. I am just concerned about the ease of cleaning and setting up which is why I have never got one. Thanks for your videos! I've watched a few now.
I really like this tank, the only thing is I think the entire filter setup is stupid. It have potential though, and I'm really pleased with it since I had some modifications done. The most annoying thing with the default filter setup is that there is about 2L or half a gallon of filter volume, but about half a deciliter (1-2 oz) of biological media, so I cut up the spunge into smaller pieces, one for the bottom and one for the top and then I had place for biological media in about 2/3 of the space instead of the tiny little bag. But I also filled in the gaps in the wall to the inlets of the second chamber almost to the top so the water have to flow from top to bottom to get maximum time for the water to actually pass the filter media, not bypass it. I'm very pleased with how the filter turned out, it's a huge filter for such a small tank!
''wauw that's interesting.. if you want to give your fish a seizure or something." LOL! I just purchased this aquarium myself and my first thought with the 'thunderstorm' function was indeed: ''Ok, but why?'' ..
Another great vid! Can't wait to try this Flex out. Fluval's designers certainly have been spending extra time in the "think tank." Love your unboxings!
Hiya!! I kept fish for 25 years in tanks up to 260 litres....but sort of drifted away from the hobby about 18 months ago.... However, the word "nano" intrigued me and although not technically nano, I have today bought the 57 litre flex based on your vid (and a couple of others) 😀. I just wanted to let you know that the tank is now fitted with two removable smaller opening grids that clip over the rather large channels in the flex! I am not 100% sure but I reckon the slits are narrow enough to keep most fry and Khuli loaches out!!! Now I am staring at my tank hoping the heater I have ordered arrives tomorrow so I can get it stabilised and begin cycling at the weekend!!!!
I have the 34ltr with embers and amanos and the lights I find are great my tank is so overgrown withing a few weeks of trimming back I love it. Thanks for the video man 👌
I'm getting the black one from my sister's husband as a surprise gift I found out about today! And I absolutely love this aquarium! I don't have it yet but in few days they said I should have it. Which makes me excited. They are personally buying a nice stand for it on Amazon as well for it. And I know it's going to be absolutely gorgeous when fully setup. Love your video I'm a new subscriber and will start following you for this aquarium.
Hi mate how is it going with your new tank I have just got the flex 123l they are amazing I would get yourself a filter basket for where the big sponge goes
Great video! It helped me decide to get this tank :) They have made the grates in the back smaller, so harder for anyone to go where they, are not supposed to go :) and love you channel, please keep up the good work :D ( sorry if there is a couple of spelling errors, english is not my first language)
So, I have set mine up and waiting for it to clear, but really love it. My only complaint is how low the bottom vents are - engineering fail in my opinion. An inch or so higher would have really helped with aquascaping. My fix was to take a prefilter sponge (had one handy) cut off the end and then cut laterally. Opened and pressed against vents, attaching with black zip ties. Seems to work, but I just don't think it should have been necessary.
Just bought this tank and thanks for the tips on how to set it up. I don't think I'll be giving my fish the 'lightning treatment' but the nightlight idea sounds great. A really cool informative video :)
didn't realise i would have to remove the whole lid /lights and plug and find somewhere near to balance it all Or take the plug from the 3 way extension. Hinges would make a whole lot of difference. I already have an edge, which so far is a better set up. Excellent flip up lid and heater /filter only taking over a corner ,so more useable tank space. But... I was drawn to the shape of the tank/stand and the lights... 🙂
Use moss meshing and glue it on the inside of the sump where the wholes are, then add some more sponge in that area for extra filtration. That's what I did with all mine with sumps like that.
This tank is defiantly made for moding. the large back allows to add bigger more powerful equipment. (Saltwater) the only complaint is that they did not make a Light mod for a coral light. The lid it too low to really add to the lighting. great video and set up!
pecktec I know the fluval evo has the same sort of design for the filtration and the lid has the same cut out. I think the flex would look cool as a mini reef of course the light would need upgrading
Great video. We bought two Flex 15 aquariums from Amazon last week (No LFS carried the Flex). When they were delivered one of them contained two plastic 'auxiliary' filter port covers/grates that snap onto the existing filter inlet ports. These 'aux' grates have much narrower openings. I assume this is a 'new' feature of the Flex that will (should) become standard going forward.
You're a bad influence on me. After watching this video, I checked on line and found the 15 gallon for $170.00, but before clicking 'buy', I checked my LFS and found it for only $150.00 Score! Fits my new stand perfectly. I unboxed it, really could have used the 'mega' and plan to 'scape it tomorrow.
Hi just recently found your channel and have been slowly going through your excellent videos....really enjoying the journey.....thanks for sharing.....Chris from the uk
This tank has only 10.9 gallons of volume for the fish to dwell in, the remaining 4 gallons are for the filter section at the back. The dimensions are 14" high, 16" wide, a curved depth max of 12" and min of 10.5" (11.25" average depth). If you buy this to replace your 10 gallons tank, you will be frustrated like me.
Online my LFS sells them too. Bio if your using two you can swap half every 6 months. The sponge Maybe once a year. I don’t replace the sponge but I swap out the media now and then when I start a new tank. If you rinse them regularly (in De-chlorinated water) they last a long time.
after you filled it up and I saw the light I think you'd be able to grow a carpet in that tank. Maybe something like utricularia graminifolia. It's a short tank and 7500K LED's is good enough for a tank that size
