Hope u clear it up soon

Just found out they are some sort of macro algae. The more i try to get them out, few more sprout in some other place. Kinda irritating tbh. Nitrate is at 5ppm, phosphate im not sure. I do dose liquid phosphate remover weekly though. Anyway, care to share why they are the bad kinds? Or not good? I would think they are much better compared to diatoms or slime algae.

It's red bubble algae (pest algae) and the only ways to remove it is without taking the rock out of your tank is either manually(remove the whole algae, roots inclusive), nutrient denial(lowering nitrates and etc) or getting appropriate herbivores(nearly no herbivores munch on these kind of algae). Or you could also take the rock out of the tank and blowtorch it, dip in bleach for a few hours or leave it to dry out under the sun

Thanks for the tip. However i do think that blow torch and soaking in bleach a tad too extreme. Lol
