Well i just got my 55 on sat. and have been messing around with some my base rock i have.. Heres some crappy pics i got from a camera phone lol .. I have about 45 lbs in my 29g im going to be using also so don't worry, I also have about 15-20more lbs of base if needed.. Im going to be using a Hydor #4 for the flow.. I want to try to get some rock in the path of the flow so it will break it up some so my softies won't be blown away, im waiting for my canopy to dry ill get some pics of it tomorrow, It doesn't look the best but w/e lol.. I also am going to try to see how this works, insted of getting expensive reflectors im going to line the inside of the canopy with tin foil.. its shiney and reflective so why wouldn't it work? I still need 1 more ballast for my light and just ordered 2 'knock' off bulbs from ebay for 40 bucks.. I should have my other ballast in 2 weeks or so.. Im in no hurry as i don't wanna have to redo any of this! anyways enough talk heres 2 pics, im trying to hide the powerhead if you couldn't tell!
