I have a few questions... I am switching my 90 gal over to sand, and a good portion of the water to RO water. I kept the LR in buckets and rubbermaids in water... i forgot to put a heater in some of them will this kill the the bacteria that is used for filtration in them? Also after i re-ad the LR and the sand and fill it up with the RO and get it all balanced out will it go through a mini cycle? or for that matter an entire brand new cycle? thanks for your help.
