how much water change on first cycle?
im just wondering what % of water should i change after my first cycle. so far i have about 40lbs of live rock and 60lbs substrate...i plan on gettin more rock later. as for the tank it is 65 gallons with a 40 gallon sump with filter floss. i have 2 power heads but i don't have proper lighting and i dont have a skimmer yet. also, what would u suggest for a clean up crew...i was thinkin about 20 astrea snail but i dunno wut else to get? when should i introduce them to my tank?
