How filter placement changes your tank's flow - Hang on Back Edition 

This is incredibly helpful!!! Thank you! Now I’m off to go top off my tanks….

Would love a Sponge filter placement video please. You're not dummy and you have broke this down beautifully I look forward to more 🥳

Oh, this is a particularly good one! I hadn't stopped to think it through like this, thanks!

I’d love to see a canister and sponge filter one. Planning on sponge filters in next tank to start but plan on switching if it isn’t keeping up the way I want. Would be super interested in how it would change my flow if I were to switch to a canister. Also appreciate the dumbed down version. The science behind it doesn’t help me make a any more of an informed decision than I can make with just the dummy version.

Thank you for taking time to explain all this.

This is excellent and I needed it in my life more than you know!!! Thank you 😊

Your advice was very helpful, thank you!

Fabulous video Bentley very informative and easy to follow, for us dummies 😊. Take care 🤗 💕

Yes please 🙏 this was sooo helpful 🙏 need to do one for sponge filters! ❤️ thanks sooooo much for this

A canister overview would be great and maybe the positive/negatives that come with a spray bar vs traditional nozzle outflows

Thankyou Bentley, This helps a lot

Lovely video. Thank you. I have never watched a detailed video on the HOB filter for two years.

Well explained, Bentley!

Great information here Bentley! 👍

Tank tested had a pretty AWESOME one for spraybars with pictures and a lot of orientations I never thought about. Addendum, showing the HoB with those Etsy baffle things.

Excellent video

Bentley good job explaining. In my 40 breeder I'm running a title 75 on the side of my planted tank. Also running a small power head and 2 sponge filter and my tank does well pushing detritus to my filters. But it's good to understand the differences of placing filters

Aaaaaaaahhh... LOL i learn so much from you it'a crazy. I've been fish keeping for 5-ish years, got 2 hang on back on my 20 gal long, and believe it or not i've always has the little fall i thought that was the way ahahahahahahaa that explains way too much of my struggles in 10 mins lol

Great information!

This is very timely for me! I'm running into more detritus/mulm build up issues as my vegetation gets more dense. Since I've got a small herd of cory's at the bottom, they're constantly kicking up debris lol. The heavy vegetation is creating dead zones, and even with my filter configured in your latter suggestion, I'm still getting mulm settling on plant leaves. I've bought a pump for more circulation and have yet to install it. Hope it gets the job done lol

👍🏻😎Great topic and explanation.

The Bentley bat phone is amazing 🤩 recommend it!

Thanks

Nice video!

The nerd is strong in you. You might even be the chosen one of legend.

Yes, please diagram the water flow using a sponge filter. Thanks!

Great video Bentley, thank you. I have a 90g with FX4 and power head. Water has particulates. I’m going to add a HOB or Sicce shark. Would love info on canisters.

I prefer mine on the back, either big one in the centre or two smaller ones on each side. That way you have areas of lower flow which I find works better for the average community. River tank with fish that like faster water, put it on the side. It does seem to me sometimes that people overdo the whole flow thing, almost like motorheads competing with their engine sizes. Seen to many tanks where the fish are being blown around. Good vid as always!

Please make the video on canister filter and sponge ones . This one explained so much about what goes qrong

Super informative. Can you do one on HOB and co2 doffusor placement. Would be amazing

I have 2 Tidal 55s on the back of my 37 gal tank. The skimmers are blocked but for a small strip at the top. My logic being if the clean water is entering from the top, you want the maximum pickup at the bottom. I went to Tidal, as I simply got tired of decades of fiddling around with Aquaclears to get them running after maintenance/power outages. I'd definitely like to see additional footage on both canister and air driven filters.

Thank you for the video... I just purchased a Tidal 75 yesterday to replace my JEBO canister filter on my 55 gallon goldfish (only 5 fish) tank. The canister filter really wasn't doing a great job because even within 5 days of a water change and cleaning the glass, the algae accumulates so quickly. I really wasn't sure where I should place the HOB... either on one side or in the center.

Thank you for this series! It’s so helpful 🙏🙏🙏 i’m rethinking my filter/powerhead placements in my tanks. What if you have floating plants tho? Does that hamper the flow up top from circling back strong enough? What do we do then?? 😳

I would love to see cannisters. I have a GLA 22L with double intakes and a flow tamer spray bar which is double drilled. I have fancy goldfish in a custom built 36 x 20 x 28. (very size specific for the space it is in) that is why I need a really good filter...my fancy golds are water pigs. BTW I also run a plenum UGF in the Dr. Novak style. Yes I know I have over kill filtration! Just would like to know how you would set up the intakes and spray bar for maximum flow filtration. Thanks...love your videos, they are always full of great information. You taught me all about aquarium lighting...thanks for that. Teri

I am very interested in hearing about the canister, especially where they are on opposite sides and both in the back of the tank.

Hardscape can be used to modify your currents to mitigate low flow zones in your tank if you wish to be fussy about it. In some cases you may want to be this picky, in others it doesn't matter. A great way to maximize flow using a Tidal 35 in a 20g high tank is to have a piece of log-shaped driftwood running side of the tank to the other side sitting at an angle so there is clear space underneath the log. Tidal goes on the back of the tank. Outflow will run along the surface of the water, back to front, then when it descends it will tend to circle underneath the log. I can see this happening as duckweed shoots across the surface, down towards the front, under the log and back up towards the filter intake again. A completely unintended benefit of this is that the duckweed gets stuck underneath the log where my snails like to hang out and eat it all (the snail species in question loves plants). It's perfect.

Yes to seeing sponge filter edition. I've oddly never considered that my intentionally lower water level is impacting my low flow areas of tank, and it is suddenly obvious that it is. I just assumed my low flow areas are from plant growth and poor plant placement and as I don't want to disrupt some prized plants, I pay more attention to debris in those areas.

Please do one on top filters...!

interesting video, i was just about to buy the highly recommended tidal 35, but i was concerned about the lack of the extension at the inlet. is there a way to extend it?

Thank you Bentley. Very helpful video! Can you please make one more video about when setting multiful filters. I like to use more than one filter and the main filter I like to set up is a canister filter. I always wonder how I should set up the flow direction.

With the concept of a plenum and anoxic, wouldn’t you prefer more detritus? How does fluid dynamics work with a weir and a plenum without an uplift tube?

With a canister I keep the intake at one end and the outflow at the other end.

I have a 75 gallon freshwater small fish community tank (kuhli loaches, cory doras, tetras, danios, guppies, and mollies) with an AquaClear 110 HOB on the back, so half of my tank is almost stagnant. I've played with both a wavemaker and a powerhead (not together). I just can't seem to decide on placement for either to optimize the water flow for keeping my tank clean and keeping the debris from settling and not moving to the hob filter. Any suggestions, diagrams like the ones you're doing now would be a great help!!! Thank you!!!

Plz make video on canister filter

60×30(cm) shallow tank. Filteration will be 2 small HOBs - how would you place them?

👍🏻👍🏻

Hey Bently, where should I put a sponge filter to a HoB to maximize flow and detritus pick up? from ur bad drawing I guess the opposite end on the substrate floor, where it churns?

yes please - just upgraded to fluval roma 240. need help to maximize flow. do I add a 2nd filter or a just a power head/wave maker? - HELP

Teach me all the things bro

thanks for the video I learned a lot. I have 4 tanks using 3 types of filtration. 🧽, Hob, & canister. I would like to see a deep dive on canister and sponge filters please. Especially optimal placement of intake output of the canister

Please deeper dive the placement of the different filters.

Wouldn’t air stones at the other side of the tank help with the movement and pushing the water in about a 20 gallon tank. I unfortunately bought a filter system recommended for a 20 gallon. I didn’t one up it

You missed the corner box filters for review

I am wondering whether this info is based on actual science or your observations? Dont like looking at an hob in center back of my rimless tanks...but will move them if better overall. Mine are at sides now and eventually will try canisters....

Where’s the canister overview?

Have you been checking out my videos? Until this. never seen anyone explain this before. One thing you didn't mention is. Hob filter restart. A lot of people complain about the best hob out there the aquaclear. That it won't restart after a power outage. If you keep the water level right they have no problem restarting. The tidal hob is crap. The only thing they have going for them is the pump is in the water. They don't skim. The media capacity is a joke and the sponge that comes with them is almost non-existent. Plus is the water does get low they're ridiculously loud. Anyways keep your water level just above the lip on the exit ramp of your hob's for proper filter performance. That goes for all brands.
