I recently have started to upgrade my 30 gallon to a 55 gallon, i have a brown algae problem.. but ive tackled that as well, upgraded my skimmer, increased water movement, and i also run GFO, but while im upgrading i think it would be best to start from scratch. I want to get rid of all the algae from my liverock and sand, because i will be reusing them both. What would be the best way to do this? I was thinking of scrubbing the rock with a brush and giving it a dip in RODI water. And for the sand rinse it with a weak bleach solution. any suggestions?
