I recently setup a new tank (cycled for 4 to 5 weeks)? It's been running 3 weeks (after the cycle) now with fish and corals.
My question is How long should I wait before I do my first water change?
how many gallons should I do on my fist water change? Ive been luck to not lose anything during the transfer
It is a 120 gallon tank transferred about 20 gallon of water from my 34 galloon aquarium during the cycle.
