Hi R2R Team, I've been battling a nuisance algae for a little bit now. I initially thought it was bryopsis but have tried fluconazole with no luck. I have tried manual removal which will remove the amount initially but always comes back. I have also implemented reduced feeding by reducing total...

Hi all! I seem to be having an issue with a nuisance algae. I would like to see if there is a "natural" solution to the problem before I try to attack it with chemicals. I have a starry blenny, a blue spot sea hare, and a smorgasbord of different snails, but none of them seem to touch the stuff...

Good afternoon! I have a 6” magnificent Foxface that I ordered online that I’ve had for 2 weeks now. Still a little shy, but has been getting much more bold in the tank. The problem I’m having is with feeding it- the fish is only grazing in algae in the tank. I feed LRS reef frenzy and mysis...

I need to clean a rock out of water since it's full of GHA and I estimate it will take about 30 minutes to scrape it all off, spray H2O2, let it sit, then rinse with SW. I also have a mushroom on this rock but since it's on the lower part I can keep it submerged. Also, is spraying H2O2 really...

Hi all, I had a turf algae issue and used reef flux to kill it. I moved my chaeto to another tank during the treatment. It has some turf algae knotted into it. I do not want to add it back to the refugium with the turf algae in it in case that could add it back to the system. Is there a way to...

Hello fellow reefers, TWO QUESTIONS i. Anyone’s expert opinion on whether or not keeping a plant grow light in the same room as my aquarium is okay? ii. Also, could this artificial sun be the dominant factor in causing my excess algae growth? I have a quite young (6 weeks?) fluval evo 13.5...

So i’ve seen plenty of different methods to use H.P. to kill GHA The one that works best for me in to apply 1ml of 3% H.P. onto the GHA on my rocks (since they’re too big and have too many corals to just be taken out) My question is: can i use the one found at drugstores? Or do i have to go...
