20G @ 4 months

Whats your lighting for the tank?

3x15W : 1xactinic, 1xdaylight and 1x50/50

you can check my specs on other pics I have (earlier pics)

BTW, the top "things" is no lps/sps coral if that's what you worry about... That's only a dead coral rock with some zoos on it.

i like the set up it looks great, i had a question, im setting up a 20 L and im not sure about the powerheads and how to get the current right how did you it on yours and any advice

I have 3 pumps: 1 aquaclear 200, 1 fluval 3 (head only) and a powersweep 226. Please, don't buy the powersweep, will only sweep for 2-3 months then will be unmobile... buy another head, cheaper and more powerful

I have around 450GPH which is ~22x my tank. Put a head directed in a lower area and another one near the top (powersweep ni my case) and leave the aquaclear without filtration media... if you'd like, you can buy a bigger aquaclear and try to make a fuge/sump out of it, which seem nice, but a bit small for a 20g...

That's about it, feel free to ask more

Hey thanks for advice on the powersweep i was considering one but not anymore, and yes im doing the all to popular AC500 into a fuge for my 20 L and turning down the flow to very low, im thinking of getting two powerhead aquaclears and having them set on a wave machine timer. But im not sure what the timer should be set at like if i should have one on and one off alt ever couple minutes or what any advice. thanks again man
