Yo, I've got the same reactor on my 90-gallon. Took me a week to dial it in. Keep your alk test kit handy, and don't rush it. My tank's alk was 8 dKH when I started, now it's steady at 9.5. You got a pH controller?


A pH controller's a game-changer. I've got mine set to cut CO2 if pH drops below ...

Start slow with the CO2, like 1 bubble per second. Test your alkalinity every few hours to see how it's affecting the tank. I run mine at 1.5 bps for a 150-gallon system, but every setup's different. What's your current alk level?

Thanks for the advice felinxo. I'm curious about the vermatids, how exactly do they cause bleeding? Is it the shell itself that's the issue when they're broken? And just to confirm, you don't think coral Rx would be enough to kill the vermatids or get rid of the sponge?

I've had my Duncan frag for about 5 years now, and it's come a long way - it started with two heads and now I've got around 30 living ones, plus some that didn't make it. There's a dead skeleton in the mix, with sponge growing on it and a bunch of tube worms attached - I'm pretty sure they're ...

Thanks so much for the advice, really appreciate it. We were thinking along those lines, but hadn't considered the quarantine part. However, we're a bit stuck - what if we don't have access to a quarantine tank? Is there another way around it, or are we out of luck? Thanks again for your help.

Hi everyone,
Just setting up a new marine tank and we're starting with the easy-going fish, like clowns, after doing a ton of research.
But we have a concern - what if something goes wrong with these gentle fish and we end up losing them?
If we're left with the more aggressive fish, how do we ...
