DIY Refugium from 2.5g cube?

[smarie]

I have an IM 25g Lagoon AIO tank. I have an extra 2.5g cube left over from my freshwater shrimp. What would be the best way to turn the cube into a refugium/macro algae tank for the 25g? What would I need to do this?

Honestly, having owned a pair of IM Fusion lagoon tanks - you're probably better off with a HOB refugium (InTank offers one that fits in the middle chamber on either side of the main pump chamber).

Currently in the process of doing this with my tank. Let me snap you some pics

I used some cheap 1/2” pvc elbows and some barb fittings to create a little overflow and return. It will be in the 2nd rear compartment

The siphon will be controlled by a ball valve, and I made sure to make the hole just enough below the surface in case of a power outage, it won’t drain the tank enough to overflow the refugium. The return will have a check valve to prevent back siphon as well.

I will be putting it in one of my lower chambers of my stand, lighted with a refuge light and timed with a little kitchen timer.

Let me know if you have any questions.
