Picked up a 55gal out of the local trade paper for the rock and substrate out of it for 100 bucks so i thought why not drill it and set up a cycle tank while im working on the 180. I got 2 over flow boxes off ebay for 45 dollars each that came with the cup saws for glass they were said to be 1200gph each but when i got them I didnt feel they would carry the 180 so why not drop them in this 55gal

didnt know which would be better going to try my hand at building one instead of using a tank as i have in the past. Any good online places to get the bonding agent as it is not available local here at the glass shops

looking at some octopus skimmers and they say they have metric plumbing what kind of issues will this cause. I dont ever recall seeing any metric pipe or adapters in the states

Got alittle more done computer station almost done little more trim to do it all out of oak i had from the last stair case i build nothing real fancy but it will do

Started the tank stand the base is done needs sealed it puts tank bottom at 36in the two bottom sections are 32 wide 25 deep 32 high will prob build sump size of one whole side and pass thur and mount my pump on other side and prob a ta scrubber ...

Looking for some input on a new skimmer have a old berlin style from my old set up but its not big enough for this 180. I havent had a reef tank up for awhile or one this size old was a 75gal so not up on all the new products. If some of you are useing any of the newer brands /types id love some suggestions
