Cyanobacteria?

[JustinMN18]

I have this stuff all over the sand. 5 nitrates, 0.19 phosphate. Any thoughts? Seems too heavy to effectively siphon out. Blows off the rocks and frags very easily. Goes away at night, comes back strong during the day. Orange picture has a yellow lense over the camera, bluer one does not.

Definitely Cyano.

I just had a really bad case of it. Used Chemiclean and its like magic, gone in 72 hours! Your phosphates could come down based on your nitrate levels.

How old is the tank?

I was looking at chemiclean, but was thinking of other methods. I've been dosing Microbacter7 daily for 2 weeks, running UV as well 24/7 except for 4 hours after dosing, etc.

Tank itself is 2 months old, but the media inside to cycle and keep the bacteria is about 8 months old.

Ah ok still fairly young tank. You can wait it out as its part of the uglies phase, until other kinds of algae grow and you have increased biodiversity in the tank.

Yikes.
First thing to do is to check your phosphates and nitrates for elevated levels. Reduce white light intensity and siphon up well. Add a pouch of chemipure elite which will keep phos/nitrate in check. DO NOT FEED CORAL FOODS OR ADD NOPOX FOR A WEEK.
CLEAN FILTERS DAILY.
Add following snails:
3 nerite
3 cerith
5 astrea
3 Trochus
4 nassarius
8-10 blue leg hermits

These will take control of bacteria keeping it loose.
Add 1ml per 10 gallons of peroxide at night and 1ml per 10 gallon of Liquid bacteria during day. By day 3 you will see improvement. Go 5-7 days and it will be gone. DO NOT OVER FEED which is part of cause in many cases
other causes are lack of proper water circulation and old light bulbs causing excessive growth of Cyanobacteria.

I have a 4 foot, 100 gallon tank with 2 hydra 32s for lights, and 2 icecap gyre 2k, one on each side, ramping every 4 seconds opposite of each other. I've included a screen shot of the lighting schedule I just modified to greatly reduce the white lights. Any thoughts?

I bought some GFO today from BRS and was planning to mix in with some new carbon in my reactor to help with phosphate. Trying to get it to about 0.1, while keeping nitrates at 5. Do you think that's ok? Not really chasing, but just putting that as a general goal.

I'm using RODI water, 34 salinity, 9.0dkh, 8.1 ph.
