Hi there, I recently converted the ATO in my redsea reefer 525xl to a refugium. Chaeto is on the way so it's an empty water box at the moment.
I see three problems with return on the refugium at the moment,
The blue PVC in the front is there the water enters the refugium and you can see the return in the back. Video and image below.
I see three problems with return on the refugium at the moment,
- That it will probably get clogged easily.
- It's noisy as h*** in an otherwise silent system and kind of ruining the peacefulness of the tank.
- The suction inside the tank is sucking in air and making a slurp sound on top, but also tons of bubbles on the bottom.
