water change amount

[hoot214]

Just wanting some opinions on what people think. I have a 93 gal cube and I usually do a water change of 20-25 gal every 2 weeks. I have 8 fish 2 sps pieces, acans, mostly zoos due to pure addiction and multiple euphylia . Is my water change amount overkill.

thats alot. when i had my 93 cube i did 5g a week.

im assuming you have a doser and skimmer right?

Skimmer yes doser no(currently saving for one and open to recommendations on a good one that won't cost an arm and leg), but I'm hand dosing and testing regularly, never had any problems with levels dropping, mine are staying constant

My system is roughly 50 actual gallons and I change 5 gallons a week. Generally its better to do smaller water changes more frequently then to do large changes which could cause the tank params to swing dramatically.
