Hi Mavvy and welcome to Nanotank :gh:
Sorry to hear you're having some problems with your 2.5 Hmm...sounds like you're testing your parameters and that all checks out okay. What brand of test kits are you using and have you used them on other tanks?
Did you do the initial water makeup...
Anyone know how? I made a little overflow box for my 20 (see here http://www.nanotank.com/viewtopic.php?t=85) but I don't want to lose all that space in my 5.5. Has anyone modified the intake tube to do a U turn and suck water from the surface?
Yeah, I actually got mine at an electronics store for $16.00 w/o the power supply. I'll check out that EPO place. Actually I think I've been there before. Maybe I'd put one on one side blowing in and one on the other side blowing out. Sound good?
