Hello I’m new to this forum I’m setting up a 40 gallon reef tank it’s an all in one system that is going to be ran with light filtration I have a question regarding rocks tho I had a previous tank with some rocks that got infested with GHA and so I’ve been researching a lot on how to clean that, I ended up just putting hydrogen peroxide on them and rinsing them a ton. they looked okay but after putting them into the tank I noticed some residue. Just wondering if that’s a big deal and any further precautions I may want to take I plan on cycling for 2 months before adding anything besides CUC. Any help is much appreciated
