Angry Algae

I've Been having red and brown cayno bacteria. I've used all the cayno stuff to get rid of the cayno. Cheato keeps bringing nitrates to zero. I've been dosing nitrates now I'm back up to 5.0. My phospates are now at 1.8. I've been doing water changes. My CA is 500. Dkh was 6.8 bringing dkh back up. I noticed the outbreak when I added the T5s to my hydra 26s. Shrimp, snails, starfish, anemone, sps, lps, zoas. How do I get this algae out without nuking my cheato and inverts.

1.8 is really high. GFO will do but you would need a lot. High phosphates are lowered better with Lanthanum, BUT, it has to be done with caution & dripped into a filter sock.
When the numbers fall below 0.2 use GFO. Read up before so you understand it.

For sure, you want to get those nutrient numbers stable.

I found with cyanobacteria it's best to implement a step by step attack that wears it down to the point that a knock-out punch can be delivered. Something like manual removal every other day for a couple weeks, followed by a chemiclean treatment, followed by a 3-4 day blackout and finished with a large water change. This worked for me.

Manual removal and a large water change (30-50%) will help at first. You should try to determine where the phosphate is coming from (old rock, sand, water source, overfeeding, etc.). Chemiclean may get rid of the cyano temporarily, but if the water quality doesn't improve it'll just come back.

Thank you all for the helpful comments. Now my phosphates are .23 that's by using chemipure blue. I don't have old rocks I used the caribesea shape rocks, the tank has been up less than a year. I have to admit my refuguim was bringing my nitrates to zero so I was feeding more and dosing nitrates. I've now stopped the nitrate dosing and the nitrates stabilized to 5.0. I'll stop feeding so much. I also added T5s to my system, maybe my light period is too long?
