Well his SG is low, like 1.022 usually in his pre mixed and his display tanks but I like to keep mine similar to his because I buy all my fish from him so acclimation is easier. Could that be why its low? But I'll ask what mix he uses and just keep an eye on it
But for phosphates how i said it came out practically clear, does that mean its low? It didn't seem to match any color on the card
