Iv had this tank for 4 months now. And iv had nutrients crash before where i hit 0 phosphate, and 0 nitrate. So after i started dosing those two. My corals and everything looked much better. Till dinos showed up. But it got way better in 3-4 days started to retract. But now i woke up to cyano showing up on rocks. What should i do? Phosphate is 0.08, and nitrate is 8.6 according to hanna. Salinity is 1.025, and temp is 77F. Alk is 7.4 with tropic marin pro salt.

In a new tank like that I would say try to keep detritus buildup to a minimum. Blow off rockwork daily with a powerehead or turkey baster and vacuum sandbed routinely.

While I agree with waiting it out and blowing it off of rocks, if it is driving you nuts you can also manually remove it every few days. I took .25" clear acrylic tubing and cut one end at a 45 degree angle and attached a silicone hose to the other side to make a small siphoning tool. Every few days I just siphoned the Cyano into a filter sock in the sump or a bucket and returned the water.

Also, you can try @SunnyX method of dosing Microbacter7 and Calcium Carbonate. See below:


Just keep up with routine maintenance and like others stated, it will balance out in due time.
