I've ran low-tech planted tanks for several years now...and I'm ready to take it up a notch.
In the next few weeks, I plan on getting a 40g breeder, and doing a med-high light, pressurized Co2 epic tank.
I currently have a low-tech 20g long up and running. I'm wondering if I should convert this 20g long into a sump/refugium for the 40g build. I'm very intrigued by being able to:
- Hide the equipment.
- Contain the filter mechanisms within the sump.
- Inject the Co2 into the sump.
My googling efforts yield a lot of saltwater-related results. I'm wondering how many FW tanks utilize a sump? I'm also wondering if this is overkill for a 40g setup?
If this is a good re-use of my 20g, are there any tried and true sump DIYs?
