About waterchanges when cycling my tank?

Hey people,

As some of you know i have a 20 gallon reef that i just started thursday. Since it such a small tank with such a low capacity of water, i know that i dont need to be dosing supplements/additives to the tank if i just do 10% waterchanges every week. Do i need to make 10% waterchanges every week when my tank is cycling? I got a little worried cause people say that live rock constantly take the calcium and alkalinity out of the water to be healthy, and i dont know if i also have to do a waterchange just when my tank is cycling? I REALLY NEED HELP!

 

Do not do water changes during the initially cycle unless the cycle stalls or you have added live stock too early.

No need to worry about the big 3 (Ca/alk/mg) for quite a while.

agreed, when you change the water too early you are diluting the amount of either ammonia or nitrites in your tank and therefore either giving yourself a false reading or slowing down your cycle a bit

 

no need for water changes during cycle. cal alk and mag will not come into play till ur tank is stable enough to support corals which i recommend atleast 6-8 months after cycle if not 1 yr.
