Rhys Posted August 22, 2019 Share Posted August 22, 2019 So I’ve had my 20 gallon frag tank setup for around a month and a half, and I have detrimentally green water. I believe it’s a bacterial bloom, but I have low nitrate and pho’s (see bottom text). Are there any direct causes for why my tank would change to a green within a couple weeks? I’ve never experienced this before. I have zero fish or cleanup crew stocking other than a single blue leg hermit crab. I have been dealing with a bit of a flatworm issue so that could be the cause as well. Nitrate: 0 (API) or a “light yellow” phophate: 0 (Salifert) or a “clear as before” Quote Link to comment
Clown79 Posted August 22, 2019 Share Posted August 22, 2019 Green water is an algae bloom not bacteria. Bacteria causes a milky white look. Phos being 0 isn't good, same with nitrates, could be the algae bloom is causing 0 readings since algae uses both. What water source are you using? 3 Quote Link to comment

I’ve been using RODI salt mix from my LFS, I should probably test all of it next time I get some. I’ve never had issues so maybe it’s a change in their process, hmm. You’re right about the algae bloom. Any suggestions for treating it other than water changes? 1 Quote Link to comment
seabass Posted August 23, 2019 Share Posted August 23, 2019 Do you have any pods. They should love it. How dark is it, any pics? I wouldn't think that leaving it would be a big problem (it should get consumed and/or eventually run out of nutrients and go away on its own); although, I agree, water changes should help. A UV sterilizer would work too. 1 1 Quote Link to comment
mcarroll Posted October 10, 2019 Share Posted October 10, 2019 What rock are you using and how long has the tank been running? How about filtration being used on the tank so far? Quote Link to comment

Tired Posted October 11, 2019 Share Posted October 11, 2019 Check your parameters, and don't worry about it. It's harmless, just unsightly. Quote Link to comment
