Hello all I’ve posted here many times and have learned a whole collection of things having been informed on how to stock the tank, setup my skimmer and all hosts of things now I’m here with a question about setting a sump/refugium but for a nano tank! Ive got a fluval evo which is 13.5 gallons of water volume Ive learned that in such a small tank every gallon truly does count and was wondering if anyone has any experience with setting up a sump for such a small tank or something of that nature, this sump would either be a 2.5 or 5 gallon or something in that size range, I’d be willing to DIY it but if anyone knows of some premade options I’d also be interested, I’m also wondering how would I go about connecting the fluval evo to the sump? thanks in advance for anyone with any input.
