2.5 Gallon AIO w/ 18 watt Current USA Fixture

[Whatigot]

drip it in.
some people are afraid of the simple stuff, but I have kept nanos ( I have a 5 gallon running for 3 months now with a diy drip) successfully with this system and its not that hard to dial it in.

if you wanna spend 200 bucks, you will have something nice and easy, if you wanna save some $ and put in a very little legwork, try the drip.

it will cost you 10 bucks MAX to build, and that isn't much to take ac hance on something you might find works excellent.
