Hello guys, I'm new to the forum, i just made a new rack that hold 2 29's and a 20 long. I'm looking for some opinions. I have my pumps running my sponge filters but i also usually run a Hang on the back as well. i have 3 Tidal seachem 35 and a 55 and im split between getting a 4th or trying an aquaclear 50. the aquaclears or so much cheaper at the moment i think i can buy 2 aquaclear 50 for the same price as one tidal 55. ANY OPINIONS??? Thank you in advance!
