Although it looks white, what color is it? Is it covering your substrate, which appears to have a slightly green tint? Is it covering the driftwood and how long has the driftwood been in the tank? Do you have any fauna in the tank? How long has the tank been set up? What are you dosing and do you have any test results for water parameters? How often do you do water changes and how much?
Iím thinking fungus/mold or cyanobacteria (which can be whitish).
Hi, it's whitish, not covering substrate, and majority of it is on java moss.
I pulled as much as i could out of the tank (portions that were growing on the moss), but it's also on rocks and driftwood.
tank has been set up for about a year, no dosing, wanted to go as low maintenance as possible so only have slow growing plants. have a bunch of floaters to absorb excess nutrients from feeding.
Fauna consists of about 20 micro rasboras, cherry shrimp, few otos, few corys.
water change every week to every other week, half the tank. Haven't tested in a while since everything has been going well in the tank aside from this issue.
It's really hard to pull off of the rocks and driftwood though, it's really on there. I think you may be correct on the fungus/mold. Do you know the best way to get rid of it?
