Possibly, I feel like I'm sort of limited on space if I want the heater to sit horizontally (which seems like the best idea), as the heater chamber needs to be like 12" + of the 20" tank (if I use my preferred heater, fluval M series). plus need another 4 inches for the sock chamber. . . . and I still don't even know what skimmer I want haha
This seems like a good, and affordable, option:
The highly-rated HOB-1 skimmer in an in-sump version!The AquaMaxx WS-1 protein skimmer features an incredibly responsive collection cup and an amazingly powerful submersible pump. It is rated up to 65 gallons in a design thin and light enough to be placed on a nano aquarium, all-in-one style...
