paulsz Posted January 11, 2021 Share Posted January 11, 2021 Just some questions for you that could help us: can you post a pic? Also, how old is the tank? What are your nitrate and phosphate levels? What's your lighting like? How long per day? What kind of light? Quote Link to comment
Clownfish king Posted January 11, 2021 Author Share Posted January 11, 2021 I’ll do a pic in a bit my tank is just over 3 months old now I had to restart it after my og tank leaked. My nitrate is 5 ppm and phosphate is 7ppm Nitrite is 0 same with ammonia Quote Link to comment

Clownfish king Posted January 11, 2021 Author Share Posted January 11, 2021 I meant 0.07 lol sorry And that was after a spike last week when I added a bit to much mysis normally it’s at about 0.05 Quote Link to comment
Clown79 Posted January 12, 2021 Share Posted January 12, 2021 0.07 is perfectly fine if anything it will prevent dino which is a bigger problem then green water. Corals need phos and its easily depleted by corals. Green water is a phyto bloom. In a new tank that can be fairly common. Just keep up with your waterchanges. 3 Quote Link to comment
mcarroll Posted January 15, 2021 Share Posted January 15, 2021 You hope that bacterial growth and hair algae growth (among other things) will outcompete it. UV would be fine and only helps that process along. Not a requirement though. Micron filtration should help some too...but again, not a requirement. Patience is the main thing. Quote Link to comment
