can u guys pls identify caue i though it was macro algase but now im starting to doubt myself:neutral::neutral:

Not sure which you're going for there. I assume the bad stuff growing on the glass? Dictyota. Yard it out now before it spreads, not much eats it.

talking about the green algae on the rock

Bump

Turf algae, needs manual removal, its too tough for anything to eat. It should come off pretty easy as it usually grows from a centralized point, just grip firmly and twist.

Will an urchin eat it? Is it a bad algae cause it's almost smothering one of my zoa frags, I also have some thick brown algae growing on some of my LR , will an urchin eat that too? I'm gonna to get and Rodi later in the year and probably a TLF reactor this weekend with some np pellets.

I doubt it on both counts. You need to seriously look at reducing your nutrient load if you have that much/many types of algae.

All of this has just really occured after putting t5's over my tank. And as for my bio load phosphate is undetectable and nitrate too low to read so idk?
The test kits are about a year old though.

Yeah I dunno, phosphate test kits are funny IMO, I think to get a true reading you're supposed to heat the water to 80C or something. I remember Aqua-Digital mentioning it in one of his threads. I just automatically assume that if I have algae in excess that I have phosphate. Right now, I have algae in excess so I am running phosban in a reactor and its slowly disappearing. I am running the NP biopellets as well but they haven't really been doing anything to help on the algae front :neutral:

I'm also scraping my glass every day cause my walls are all green this also started after t5s
