the bath tub i only put 1 cup of bleach to loosen up the algae, i then used a bbq brush to scrap off as much die off as i could, then into the oven for 1 hour at 400, when it came out it was alot whiter. I dont want to take any chances so im going to do a full out clean on the rock its now in a 50/50 bleach bath (ina syrafoam container) for 2 days then ill drain and put in freshwater for 1 day, then a baking soda bath for 2 days (neutralises PH and removes bleach) then freshwater for 2 more days followed by a week of drying lol. so 2 weeks essentially to get this rock ready but by that time my refugeum lights and skimmer should have arrived and ill get this tank ready to roll.....
heres the 50/50 bleach bath
starting to get super white and clean,
