3 owner used tank

Help needed. I have been offered a 135gallon marine aquarium with custome cherry stand/canopy, 250 gallon cap skimmer, uv, wet/dry filter, 150 lbs live rock, 3 blue damsels, 2 yellow tang, pajama cardinal, 2 eng. gobi, spoted hawk & button polyp. The only thing this tank seem to need for inverts is a good lighting system. $1000.00

I have been wanting a marine system for many years but this seems like the best deal i will see. My bigest concern is that this aquarium is in an office and has been maintaned by several different companies. I don't think i can get reliable info on copper treatments inside the tank and hence copper problems wioth the rock and sand.

Is their a reliable test for copper before I make this investment.

thanks for the reply.

I have read quite afew posts on wet/dry filtration and it seems that based on many of the more informed hobbiest this is an item i should remove or at least remove the bio-balls. Should i do this when i move the aquarium or wait untill it has re-sustained itself first.

I am considering hiring the current tank maintenace com,pany to help with the move but have nopt ruled out moving it myself. If I move it myself how much of the original water should i move withit. I would move the water in clean plastic 5 gallon water jugs, although a lot of work i could concievably move approx 100%.

whew thats a relief, i read that you should transpdort 50-75% when moving.
I have not put a lot of faith in the book as it also encourages under gravel/wet/dry no LR set-ups for fish only aquariums. The books copyright was 1996 and last reprint was 2002 so i thought it would be fairly accurate. I hope the info on fish and inverts is a little more up to date then the equipment info.

well i have ordered Eric Bornemans' and look forward to reading about some more progressive techniques. .

This forum hase been a huge help and soon i hope to get some sleep instead of reading posts until 2-3 am.
