BaRanchik Posted July 20, 2021 Share Posted July 20, 2021 I'm struggling with GSA now that the amount of plants in my tank is doubled. It's a 10g tank, understocked, with 1 female betta, 1 oto, and about 5 shrimp or so. The oto and shrimp are eating some of the GSA but they barely have any effect on its spread. I am dosing 2ml of Seachem Phosphorus every 2 days (which is about 8 times more than the recommended amount) to get the phosphates from 0.01ppm to around 0.3ppm. Whenever I dose phosphates GSA starts going away, but within a day the phosphates are gone almost completely again. I am getting annoyed with it since I don't like dosing daily, I'm trying to keep it down to twice a week. Anyone have experience with dealing with this problem? Should I just dose 4ml every time instead? (It's not the light because the GSA grows even in completely dark spots in the tank) Link to comment Share on other sites More sharing options...

I read somewhere that this was due to phosphate deficiency so I started dosing it based on the recommended basis. It kept dying and coming back as soon as the phosphates were gone, so I increased the amount. Link to comment Share on other sites More sharing options...

Im interested to see what it is then. Good luck I found this hope it helps i dont know how to link Edited July 20, 2021 by Guppysnail Add pic 1 Link to comment Share on other sites More sharing options...
Mmiller2001 Posted July 20, 2021 Share Posted July 20, 2021 Dose more, I'm dosing 8ppm a week. There's no problem dosing all your Macro nutrients up front (first day after water change). 3 Link to comment Share on other sites More sharing options...
