OK, getting ready for delivery of our LR group buy. Got a 25 gal. rubbermaid tub, new saltwater mixed, heaters running to get temp up, powerhead and external hang on filter for circulation. Now what, just gotta monitor ammonia and nitrates till they level off? Weekly water change of about 10 gallons sound right? Am I missing anything? How long should it take to cycle and be safe to add to my tank?
