I am finding extremely high MG? Ca and Alk not so much at least to my needs now a days. Well it's more just trying to figure out if we are staying here or moving down south. Regardless I have already started sketching up and designing my new tank. 40 Breeder drilled, 20 Long sump, return pump mag7, skimmer eshopps psk-100, lighting 6 T5HO with dual LED strips for daylight, and moonlights.
