What is the harm in doing substantial water changes?
Seems to me that all of the elements and chemicals that build up in a tank, would have a harder time building up with frequent and substantial water changes
Monterey Bay Aquarium has several aquariums where they do 100% water changes every night. The Kelp Forest tank being one of them
I am unable to imagine any harm, as long as the mixed new saltwater has no error in it
One is replenishing all of the chemicals in the salt mix this way as well, forestalling the need to add dosing systems
There is a retinue of reefers here, who discourage substantial water changes. What's the rationale for that? With all the expenses involved with reefing a couple bucks worth of salt is nothing. It can't be cost of salt, can it?
