I have a 125 gallon tank that has mixed corals. Lps and soft mostly but I recently added 3 sps frags. My nitrates were at 2ppm but a week or so after adding the sps it dropped to zero. I dont want to use stomp remover. But my big question is I gave another smaller system that always has higher nitrates could I swap water with the 125? They both are disease free and very close on all other parameters. Thanks in advance
