i have a 20L. the light is not very high. indirect sunlight for a few hours in the morning. thats all.
i decided to do the first part of one two punch. i put 5 tablespoons of hydrogen peroxide in the tank and just mixed it around. i only have a sponge filter on that tank so i just used a cup and swirled the water around for 15 mins. this is my betta sorority but it also has saimese algae eaters and neons. i took out most of the bettas but left some in to see what happens.
i removed 80% of the water after 15 mins of stirring and the fish seem fine. i am going to wait an hour to see if the fish are still ok. then i will add the rest of the bettas back in.
i have anacharis, dwarf sagi, microsword and a few diff anubias. anacharis kind of fragile so ill see what happens in the next week or so. i also saw a feeder shrimp alive in there.
on a diff tank.. 55 gal... i used maracyn for 5 days at full dose and did a black out during the treatment. the BGA has not come back after a few months. the reason i am trying peroxide instead is because maracyn gets expensive.
