Re: 500 Gallon Tank

[Tom DeBenedictis]

Yup definitly 100% water change with RODI water.I did this once with a 500 gallon tank with over 500 lbs of rock .We set up different stations with rubbermaid tubs.We filled 2 with the water from the tank.One for scrubbing and one for rinsing.We also had a one tub with freshly made SW for choice rocks.And another for the rest.We took out each piece scrubbed it then rinsed it then rated it.Previously I went to the auto parts store and bought a couple of engine brushes and they worked good.I carefully inspected each rock .I guarentee you'll still find some cool stuff regardless. Some dirty tanks grow some interesting things. Anyway till this day (1 1/2 yrs later) it still looks great but we added a ETS skimmer which given the choice again I would go with Rons. Both the one we bought for my friend and the one I have completely feel apart because of bad welding.Hope this helps and let me know if I can help more. Tom PS I personally would not let the rocks dry out!
