This will be a build log for my 55 gal tank.. I like to look bad from time to time nad see how the tank is progressing.. you can follow along to help mock or enjoy

your choice.
I'll take pics later today of what I'm starting with.. Right now I'm in cleanup phase..
The tank and gear is all used and in need of a big cleanup.. I've had the pumps soaking in a vinegar/water bath all night and they are finally looking good..
I still need to get a new return pump.. When I took the tank apart to bring it home the power cord fell out of the housing.. No safe way to fix that that I know of.. I'll prob go get a QuietOne 2200 form PetSmart.. I've used them on other tanks and with a 1" riser it'll outflow a pair of 3/4 overflow siphons and 1" drain line. Knowing that I'll put a ball valve in the riser..
As for the tank it's a 55 but looks thicker than most I've had.. Maybe I'm just being optimistic

It's been drilled for 2 drains and 1 return line.. Looks like 1/2" PVC.. As is the 2 drains go to an internal skimmer box and the center return is plugged. I may use the center.. Not sure yet..
The back has been painted blue.. I'll keep it that way but I'd prefer black
Downstairs we have a 10 gal tank converted to sump and divided into 3 chambers..
1st is a liverock (dry/dead rock when I got it) filled chamber..
The heater is also in there..
2nd Chamber is the skimmer chamber with an Excalibur skimmer being fed with a venturi powerhead and pumped up with a air pump.. We'll see how well that works.
One big problem I have is you can't remove the skimmer cup with the tank on the stand.. maybe if I tilt it.. We'll see.
then a bubble trap and the final return pump chamber.
It's ugly but effective.. I may add a 2nd 10 gal or a clear bucket as a refuge..
