    Just tested my newly setup tank, only about 3 days old with dry rock...no livestock at all but this will be an LPS dominate tank

    here are my numbers: Calcium 490ppm, ALK 5.9 and Mag 960ppm

    my Alk and Mag seem really low so I am assuming the reef crystals I am using have low mag numbers and obviously high Cal #'s which are lowering my KH

    should I just let it go or raise my Mag and KH?? I am going to use the BRS dosers and 2 part when I get the money but can order the solution

    What are your suggestions???

    my PH is 7.8, Salinity 1.026, temp 79 and am going through the rise in nitrites of my cycle right now

    I am using brand new Red Sea pro test kits

    I use reef crystals as well. The alk and mag levels are much higher than that something like 13 and 1440. Here is a link that shows different salt mixes and some levels.

    I haven't tested my mix in a long time but I pretty much got those higher numbers when I did. You may have gotten a weaker batch. I am dosing pickling lime to be able to maintain those levels between water changes.

    Ok so I was reading the test kits wrong...my MG levels are actually 1200 and KH 8.1 but the calcium is only 390 at 1.026 with RC

    what is up with that??

    This may sound basic, have you shaken the mix of salt before mixing it with the water? Sometimes their product does settle out and a good shake does the trick.

    gotcha, I will give it a go...I did order BRS 2 part and will start manually dosing in a week or so once the tank fully cycles and I get the nitrates down

    Then you can stock the tank faster. :)
