DKoKoMAN’s 305g Basement Reef

WC is subjective, find a routine that works for your system.
If 10% biweekly is working out so far, adjust from there if you want to spread apart.

Try say 15-20% every 3 or 4 weeks. Do that for a while and see how the tank responds.

Some do WC few and far between, some do weekly changes religiously.

FWIW, way back my nicest sps dominant 180 got very random infrequent WC. And usually I would do 30G at a time.

Now having said that, on my new display which will be SPS dominant, I'm going to try aim for regular monthly WC of about 10-20%. (Probably 10% at 30G). This is probably on the lower end of the spectrum I'm guessing.
