JimmyTheH Posted May 27, 2021 Share Posted May 27, 2021 (edited) Hi! I have a 20 gallon that has been set up for a year, but I have been converting to a low tech planted tank over the last few months. Still trying to get the lighting and nutrients in balance. I use a Nicrew ClassicLED Plus which I had dimmed because it seemed too bright, but plant growth seemed limited so I increased the intensity to about 75% (from 50%) about 2 weeks ago. The lights are on a timer for 8 hours a day. I use Aquarium Co Op Easy Green weekly and Root Tabs monthly for fertilizer. Over the last two weeks I started noticing some white, almost fluffy growth on some of the plants. Now I am seeing more, what looks like white spots on the filter intake and glass too. Not sure what it is, if I should be concerned or just leave it alone since the tank may be adjusting to higher light intensity? Any thoughts or help would be appreciated! (Tank is stocked with 10 danios, 2 nerite snails) Edited May 27, 2021 by JimmyTheH Link to comment Share on other sites More sharing options...
Mmiller2001 Posted May 27, 2021 Share Posted May 27, 2021 (edited) Probably biofilm or fungus. I wouldn't worry about it. Do you have shrimp or snails in the tank? Edited May 27, 2021 by Mmiller2001 Link to comment Share on other sites More sharing options...

Mmiller2001 Posted May 28, 2021 Share Posted May 28, 2021 They will probably have it cleaned up shortly. Link to comment Share on other sites More sharing options...
