So I was at the LFS store yesterday and the guy on duty and I spoke in detail about the different tank setups they run. :twocents: Come to find out he shared with me that their main reef tank where the corals are placed for sale was treated a few months back with a drip of hydrogen peroxide. He said he would get me the formula they used when I got back. My question is since it has now been over 6 months since Smitty and some others tried this what has been the long term effect?:question: I'm considering scrubbing the rock to get a head start in a cooler of salt water placing it back in the tank (rocks would stay submerged of course while in cooler). Do a water change within a week and then try the drip method. Your thoughts?:Cheers:
