I have two tanks. One is SPS tank, which I do WC more often. The other one is softy/junk/too many fish and it get wc whenever I feel bored, which doesn't happen every often ..
The question is after I change the water on my SPS tank, can I use the old water for the softy tank?? I'm trying to save some water and salt ..
