What do you think about these polyp expansion?🪸 Run my tank on Modern Reef RKS.

Does anyone have any tips for this Gani? I got it for free and the guy said that he could never get it to open up.

Guys, i feel like my toadstool base is rotting, how do i stop it from rotting? (It just turns into some powder liked thingy into water when i touched it)

I picked up a Black Cap Basslet to replace a bullied Yellow Tail Damsel. The bully is a Fiji Devil Damsel. The Basslet has found a safe spot in the rocks for now. I need to get the Fiji out of the tank for peace. I don’t want to pull all the rock work out,but that maybe the only choice. Looking for suggestions to catch the bully.

Is this a Zoa? I have asked before but I didn’t have yellow lens yet and now I do.

Quick AI Prime 16 question for a new reef tank.

No corals yet — just copepods and clean-up crew.

I’m trying to keep the light low to avoid algae, but still make the tank look good.

Thinking:

RB 25 / B 25 / W 5

Everything else 0

5–6 hours/day

Light about 9–11” above the water

Is this a good starting point, or would you run it differently?

Time to change water

Looking for advice! Bought a used IM 120 gallon AIO tank from LFS. When we got tank, the inside glass was a bit foggy. LFS said fog would go away with water. We added water and things seemed ok until we turned lights on. Fog is definitely still there. This pic seems like where previous owner had his nori clip. Tried scraping it a bit. Nothing seemed to change.

Wondering if anyone knows how to clean it. Tank is newly cycled and I added fish from a smaller tank. Could move the fish back to smaller tank if I need to empty the 120. It would suck, but it will only get harder given more time.

So anyone have tricks to help? Either with water or without? Thanks yall!

How of doing people do a water change or how often should we do one. So my tank is about 4 months old now and have been doing a watcher change every two weeks. Its been through all it's cycles and now all readings are coming back perfect and salinity is also spot on. My question is do I need to keep doing a water change every two weeks if my reading are spot on or can a leave it a bit longer now ?

Any reefers near or in Plano IL!!! Trying to find a reefing buddy close or local to me/ someone i can hit up for assistance if needed!! Im 23 years old, i have a three year old daughter and my fiance and i just recently moved into our first home!

Update- Firefish went in first, Bengaii and Pink Wrasse 2 weeks later due to stocking availability. All doing well so far. Update on Week 11-12 coming soon as that was my first panic disaster week!
