My friend has picked up a 5 gallon Fluval Edge Spec aquarium and really wants to turn it into a planted dwarf puffer tank. I've given her some trimmings of my Hygro Difformis (she knows it'll need pruning to keep it in check), Repens x Arcuata Ludwiga, Sunset Hygro, and Frogbit to get her started. She's going medium-light/low-tech for now due to finances, but may eventually use some DIY CO2
I'm helping her build a custom hang-on-side 1.3 gallon refugium to give snails and shrimp a safe spot to grow and breed as beak trimming food source, and also so she has a little more water volume to help with stability. Yes, it's a probably a little overkill, but I wanted to teach myself a basic how to do it for when I build a larger system for myself in the future. Since the standard cover for the Fluval tank is really not too easily modified, plus she wants to keep it intact for later (just in case), so I'll be building a custom lid too. I've already made a screen top for my 75 gallon tank, so that part will be easy. Here's the rough plan we've got so far:
Just to clarify, the tank length just covers the non-green sections of the tank. The refugium would be an additional 4" on the side of the tank since that's all the space we have to work with
So my questions are thus:
1) Whats a good refugium pump for this little thing? I was looking at these two pumps:
EcoPlus Submersible Pump - 66 gph: Amazon.com: Pet Supplies
Rio Plus 180 Aqua Pump - 120 GPH: Amazon.com: Pet Supplies
The second one seems like overkill, but I have a hard time believing the first one really can pump 66gph using standard airline tubing... Thoughts?
2) Will having this refugium doom any hopes of having her do DIY CO2
later? I'm trying to minimize surface agitation with the refugium design, but I wasn't sure if it was possible since I've never done a project like this before (first time with Co2
Any input you guys have would be appreciated, thanks!
