I have a fish breeding setup of 10 tanks (700 L total). The sump filtration is able to keep ammonia (0), nitrite(0), nitrate(0), and phosphate(under 0.2) at decent levels. If these values are fine, is there any reason to do water changes?
I have an SPS tank where I do 10% WC every ten days or so to keep up with elements I don't measure, but does a fish only tank need that?
