Frodo Posted October 12, 2020 Share Posted October 12, 2020 Hello, Got a 3 weeks old aquarium and started to see brown algae aka diatoms all over. The Honey Gourami pair, has already laid eggs. Against my better judgement had to make a water change to get the algae control and its back in a day. Long story short- I want to take care of the fry and do not want to add SAEs, Pleco, etc. for now for their safety( although they are in a breeder net box). Any safe suggestions to control the diatoms meanwhile? They are wreaking my plants. Link to comment Share on other sites More sharing options...
StephenP2003 Posted October 12, 2020 Share Posted October 12, 2020 It's feeding on the silicates leaching into your aquarium. You can clean it off, do water changes, deploy otocinclus and/or nerite snails, or just let it run its course. It'll go away. 1 1 Link to comment Share on other sites More sharing options...
Bill Posted October 12, 2020 Share Posted October 12, 2020 Two of my tanks setup less than two months ago have this, it's harmless and easy to clean off the glass but not easy to clean off plants! I wanted to get a UV sterilizer for other reasons, but I'm wondering if I add one and then frequently brush off the surfaces if the filter will move it past the UV enough to make a difference. As an experiment I'm going to try it just on one tank. Will see how it goes. Link to comment Share on other sites More sharing options...
Frodo Posted October 12, 2020 Author Share Posted October 12, 2020 Exactly! My amazon sword looks ugly brown now. I am thinking of taking it out and cleaning. Do let us know if UV sterilizer works out for you. Link to comment Share on other sites More sharing options...
