🐠🪸 My First Marine Aquarium – DIY Reef Project

My first marine aquarium, now running for 6 months! I’m learning everything on my own and personally designed and built the sump, modified the cabinet, and installed the entire electrical system myself, including internal lighting, three protected power outlets, circuit breakers and an electricity consumption monitor.

Equipment includes two AI Hydra 32 HD lights, a Bubble Magus skimmer, Jebao pumps, a 100 W heater, refugium, bubble trap, DIY automatic top-off and sensors, plus 35–40 kg of live rock.

Currently home to 16–17 fish, crabs, a shrimp, a sea urchin and snails.

🌊 My dream is to create a beautiful reef full of colorful corals. I’m still learning, so any advice is welcome! 🙏🪸

Did I hear someone say there were snacks up here?

I have a reef aquarium with an orange Bubble Tip Anemone (Entacmaea quadricolor). The water was clear and everything seemed normal. Suddenly, within just a few minutes, the water became completely cloudy and milky white.

Just before the water turned cloudy, I noticed a white, smoke-like substance coming directly from the anemone. The anemone remained attached to the rock and its tissue appeared intact.

One additional detail: this anemone has a history of splitting and reproducing asexually, usually dividing into two anemones.

Could this have been a spawning event, mucus release, or something related to the anemone splitting? Is there a risk to the fish and corals, and what should I do immediately?

Hello all, I am brand new to the hobby. This is my very first reef tank. It is a TMC First wave 48L (UK measurement) in the past, I had cold water and tropical fish.

I started this tank on Jully 11th 2026. I'm thinking of getting some black pvc sheeting for the back of the tank, which I will put on the outside.

Why are my LPS corals tissue falling off the skeleton in the video I’m not using that much force. My alkalinity is very stable.

Tank is entering the ugly stage and has started getting air bubbles on the rock and some at the surface. Is this normal?

I’m looking for some help—I’d like to know what might be causing the tissue to detach from the base. This is the third Torch coral of mine that’s falling apart. My water parameters are good; the SPS in the tank are growing and healthy, and there is no direct return flow hitting the Torch.

Anyone else have a big bad boss of the tank fish who waits for you to hand feed them? 🤣 because same, this is Foxy - our one spot foxface rabbitfish, and she waits until I’m holding her food to eat 😅🤣 Otherwise she gets a little grumpy at the other fish because she’s 8 now and our Anthia annoys her during feeding times 🐠🪸 #fishdiaries #fishdrama

Need help with my Sarcophyton leather coral

Hi everyone! I’m looking for some advice about my Sarcophyton leather coral.

It hasn’t opened or extended its polyps for about a month. The coral is still soft to the touch and moves naturally with the water flow, but green patches that look like algae are starting to grow on its surface.

I’ve noticed that a film forms on the top of the coral. I gently removed it once, but it seems to be forming again.

All my other corals nearby are doing well, but this Sarcophyton still hasn’t opened.

Has anyone experienced something similar? What could be causing this, and what would you recommend I do to help it recover?

Any advice would be greatly appreciated. Thank you!
