OK, my 75 gallon finally sprung a leak so had to get an 80gal off of craigslist in a hurry. Built the stand, canopy, and internal filtration today, started at 5 a.m. and just now got it all set up. The internal filter is perfectly quiet, and i mean i can sit right beside the tank and can't hear anything at all, that was the main reason for building the filter, plus i wanted the tank flush with the wall, so couldn't use the HOBs. All the filter is, is two pieces of 4" abs pipe, capped the bottom of both, drilled a hole in the bottom side of both pipes the same size as my vinyl hose, and drilled a bunch of holes in the top sides of the pipes for water to enter. Connect both pipes together at the bottom using the vinyl hose and a "T" barb with another piece of hose going to a powerhead. filled both 4" pipes with scrubbies and some large ceramic rings with a piece of poly filter pad on top of each about an inch or so below the holes, i ran an airstone to the bottom of both pipes to allow more o2, but that's kinda optional. and the stand and canopy are a little rough, but i had to get this tank done today, don't have room for the spare 150gal i have and my red devil was living in a rubbermaid container since yesterday, and the only tank i could find was this one and it was tank only, been a long day.
