nuisance algae

Recently, this pink/purple foam thing started overgrowing zoas in my zoa garden. What is it? What eats it or removes it aside from manual removal? Here are photos of it on zoa frags I removed to clean. I'm thinking it is a sponge. I have been removing the impacted rocks and frags and...

Hi. I am having a persistent diatom problem. It grows mostly on the rocks, in thick beds that grow back within a few days of removal. My water change schedule is 25% change per week. I use RO/DI water always at 0 TDS, after being ran through two DI canisters. I am on well water that tests around...

Afternoon reefers... I upgraded my Fluval Evo to a 60 gallon long AIO back in August when we moved to a new house. I battled nutrients and algae (every kind) over the year that the Evo was running, mostly due to the fact I was new to reefing and made ALL of the rookie mistakes, some over and...

Hi, I recently sprayed peroxide over a live rock to rid myself of some algae. It worked really well. Now, I see some bubble algae growing in on my clove polyp and blue sponge rock. So two questions: Will peroxide kill bubble algae? Will peroxide hurt the sponge? Thanks! Cheers, rant

Hi guys! A couple months ago I set up a 75 gallon reef in which I used a few rocks from the previous system to add to the new display. I must have brought bryopsis to the new tank with the old rock. Today, my tank has quite a few patches of bryopsis on the sand bed and rock. I have been dosing...
