adding a second tank

[dmurb]

I'm thinking about adding an 80 gallon frag tank to my system. I wanted to know how I would do this. I'm planning on hard plumbing one pump into a t and have 2 valves one going to each tank the the overflows plumber back to the sump. My question is about adding new water. It's going to be bare bottom. Will the addition of 80 gallons of new salt water effect my established tank. I know it need to be the same temp and ph. But are there any major problems to doing this. Thanks for the help guys

Fill the new tank with water of the same salinity. Get it up to temp. Slowly pump it into the DT. I would using something with a low flow rate, like a Maxijet. Once it has turned over a couple times, you should be good to flow through it like normal.
