My Algae Problems Are Back Need Tips to Tackle Them! 

I use neonitro by brightwell when my nitrate get low. Its just add p03. I also don't have to worry about phosphates from having to feed more.

I second the Dinos. I had the same exact stuff. Was only on the sand and rocks. I’d recommend taking a sample under a microscope. I got a cheap one on Amazon. I dosed silicates to promote a diatom bloom which eventually out competed them.

It's all good! There's a few things you can do. You can dose Brightwells Neo Nitro - i dose 10ml a day in my tank and keeps Nitrates stable right where i want them. Secondly, you should get some snails and or a tuxedo urchin. I'm not quite sure i saw much or any in the video, but they'll def help prevent it from coming back again if your nutrients were to drop. A small conch snail or naseriths are great because they'll churn the sandbed for you, keeping the cyano in the water column. Third thing to do is put some copepods in there, dose a little phyto each day. They'll get in all those impossible places and keep your tank free from it. Lastly, and what i do for simplicity... Add Dr. Tims waste away gel sticks in your sump. I think you get around 30 days or more per stick and it naturally adds beneficial bacteria. It's the same as microbacter 7 but a hands off approach. Also would help to keep your skimmer off for 4 hours a day, this way it's not pulling out that good bacteria 24/7. You'll get it!

Boyd chemiclean is what you need,,it’s brilliant.

You are over feeding the light Reduce the light intensity 20-30% and light photo period toh 6-7 hours (including ramp up and down), dose some aqua forest life source once a week for 1.5 months, maybe dose some bio digest once a week and live phyto

I've spent hundreds fighting dinos that look very similar to that. The ultimate solution was removing the sand, I wish I had done it sooner!

I have that red algae, it comes and goes. Trochus, tuxedo urchins love it. My nitrates and phosphate are high,, like 55 and .6.

You can increase nitrates by simply increasing your feeding, maybe run your protein skimmer 50% if you have one. Just be careful not to overdo it, once your nitrates get over 10 ppm, some of your more sensitive LPS and SPS corals can die off. When I had dinos doing that, and reducing the lighting, as well as adding some Brightwell microbacter7 did the trick. Just be patient with it, and don't shock your parameters with large moves, it takes weeks and sometimes months to get rid of dinos.

SAME here I'm also going to have to bump nitrates

I being battling Dinos for a month now, and they look just like yours, I increase my temperature to 82 degrees and now I can see the light at the end of the tunnel

To me it just looks like diatoms. I would suggest doing a manual water change, siphon the sand bed to physically remove as much as possible, blow the rocks with a turkey baster to get it in the water column for your filter roller to take out (once you get a new motor for it), and get some critters to help keep the sand bed stirred (nassarious snails, conches, or maybe even a sand sifting starfish since you have a bigger tank). To raise nitrate you can use potassium nitrate. I get mine from fish of hex but I’m not sure he ships to Canada but I know brightwell has a product. Just be wary of potassium increase if you have to dose a lot as that can cause issues as well. I would also suggest doing an icp analysis to see if your minor elements are out of whack. Best of luck to you! In my experience if you just keep at it eventually it goes away.

0.30 ppm nitrate ..it is very low. btw beautiful corals!👍

I can see two nice big Duncanopsammia colonies in there and both aren't open. Did you just scare them closed? If they are staying closed and it's not fish nibbling them, the lights could be too intense maybe? Could be a real subtle amount, even just backing off 5-10% in the app or cutting the photoperiod by half an hour, I dunno..

Looks like cyano...but could also be dinos. I would take a sample from rhe sand bed and microscope it. That nitrate is way to low...i would get it above 5ppm. The phosphates are fine. The paleness in some corals is definitely the nitrates being so low.

You can dose neo nitro to raise your nitrates. You can dose phosphate I use nyos. I have had issues when my nutrients get too low. Dinos hit hard I used dr Tim’s waste away as well as his refresh. I turned my blues below 50% and removed manually every day. The struggle is real it will test your metal. Stay vigilant make a plan and keep on it . Good luck brother

looks like stringy cyano to me... I bought a fighting conch and he had an excellent buffet taking care of the sand... eats up all the greens on the sand as well. only thing bad about it is that it doesn't settle problems on the rock or glass..

Try do dose bacteria im dosing Aquaforest bios and np pro daily + more flow in your tank will help , and if you want to stay with a sand bed you will need a bigger clean up crew for it . Couch snail are amazing and nassarius snail i have 6 nassarius and 2 couch in a 120g . And to spread that shit in the water columb only vaccum the top of the sand bed you dont want to remove good stuff from the sand . Good luck !

Had my motor go just before the 2 year mark. Luckily my LfS knew about this and had them in stock.

I have the same exact tank, i think your nitrates and phosphates are a little too low, i noticed i get the same problems when they get that low

A UV sterilizer set to the correct flow rate will do wonders for clearing that up.

Conch, zombie snails, snails, and diamond goby

I feel bad for you, buddy. I hope you can sort it out, but this is exactly why I finally had enough and sold everything and left the hobby. I battled my sound like this for two years.

I had good luck with a sand conch

Looks like you reef mat is trying to increase your nitrates for you 😅

Where did you order the reefmat motor from? Mine has the same issue

your bottom seal doesn't look so good you should check it out

Shame it's come back so bad again, looking at the test results nothing really stands out, po4 at 0.6 should really cause that, so I would say say low nitrates and the simple answer is more feeding. I would back your lights off just slightly in the high intensity time of day just for a week or two see if that helps a little bit. I would just suck up as much as possible when doing your maintenance. I had the same early on in my tank looked the same, was pulling that much out with clumps of sand when it cleared I had to add another 20lb bag again to top up was not ideal but been lucky since then ☺️

A clean up crew

Turbo snail 🐌

try feeding more!

The best way to get out of this mess is to slowly bring nitrate level at 5 -6 ppm and keep them there until its improve, don t feed more, use nitrogen only supplement it s all about ratio ... too much phosphate you get cyano ... too much nitrate you get dyno... so i try to stay in between : )
