Anybody have an idea on why this algae keeps popping up in my tank? It fills up quick on the bottom left corner with some patches scattered throughout the tank, I was thinking of using phosguard because I suspected it could be silicates but that doesn't feed this type of algae and I don't have diatoms, I also don't want to lower my phosphate since it's already at a good level

Nitrates: 14.5

Phosphates: 0.05

Sand looks really clean otherwise. Nothing eating eat?

I only have hermits, down to like 2-3 snails, 2 shrimp and 1 urchin

Looks like a flow/detritus issue. I dealt with the same thing before and it wasnโ€™t fun, more flow and manual removal during water changes made a big difference for me.

Time to add another wave maker

That green algae looks like it could definitely be a flow dead spot issue since itโ€™s mostly on the bottom left corner. Maybe try adjusting your powerhead or adding a small wavemaker to get better circulation there. I had something similar and once I tweaked the flow a bit the algae stopped

That would make sense since I only have 1 wave maker and a bunch of rock in the middle that forces me to point the output all the way up, otherwise it would be hitting the back of the rock scape

Flow probs for sure that corner looks kinda dead zone wise might try a powerhead shift or something
