My 15gal tank has been having some troubles with GSA for a couple weeks now, and it's starting to irritate me. It was on the glass only for a while, but now I can see it on my s. repens really well, as well as my anubias. I have one nerite snail, but he doesn't seem to be doing much.
I have heard that this is a sign of low phosphates? I am getting a test kit in the mail soon and will be testing that, but if this is the case, how exactly do I add phosphates? Note that I have 5 African Dwarf Frogs, 3 amano shrimp, and 3 otos in my tank (as well as the Nerite and miscellaneous snails). I want to make sure whatever I do is safe for them.
Any product recommendations? Any help figuring out the dosing would be much appreciated!
Note: an API master kit + some other tests are coming in the mail, been having some problems with test strips. My water is kind of hard.
RO Question: How would one go about cutting their tap water w/RO and how quickly/slowly could I introduce such a mixture into my tank, without hurting the animals/plants? I have very hard water, and it seems to me that softer water is better. My tap water is around a pH of 7.5, with a KH of 40-80ppm, and GH of 60 ppm (it's a range bc the colors aren't completely clear, again will edit w/test results soon!)
Or is it not worth it? I don't have CO2 (I want it so bad bro) so I think this is the next best step for my plants. LMK
