Yes that's usually the cause. Co2 fluctuation not so sure as Co2 is stable unless my regulator is acting up. Would have to check that up. Flow distribution... umm could be although I am using a spray bar that is nearly the length of the tank with little obstruction. It's a 60cm tank. I am using an Eheim 2215.Looks like some sort of thread algae and maybe staghorn algae.
Either way the cause of both is probably low or fluctuating CO2 and/or poor CO2 flow and distribution and maybe organics build up.
I do use Hydrogen peroxide sometimes but I am always concerned about burning the young buce leafs or even the roots. What you guys thinks about that?Looks familiar, i have something like that too, with the naked eye and by feel i thought its Clado or something.. But i also noticed it branching and now i think its actualy a Characeae sp. Because if i look at it under 60x magnification (pocket microscope) it looks more like a plant than algae. But it hates H2O2 and can control it a bit with using this sometimes to spot treat.
Why so? They are easy to care for.Mollies in the past and they also eat it, but these are not realy my favorit fish to keep.
I used to have 12 CS in there but half died when I didn't so a water change for 2 weeks, or so I think. They might have died for other reasons as well. Never found their bodies but that's probably because there is 1 Clea Helena in there meant to take care of casualties like these. With 1 Clea Helena I know it will not reproduce so it's ok to have it.Try Amano and cherry shrimp, see if that helps.
