    I have recently made my first batch of macro and micro ferts using dry fertilizer and R/O water. I followed the PMDD+PO4 method in the EI thread (PMDD style EI). My macros will not stay in solution. Is this normal? i was thinking of not mixing in the GH booster and just adding that at water change. Should that help? Or does the mono potassium phosphate and the potassium nitrate just not stay in solution? Maybe there is something i have misread or missed. Please help. thanks!

    I don't know about staying in solution. I never went the prepaired route myself.

    However when I was premixing with tank water I did notice the GHbooster would clump up like little bits of gravel at the bottom of the measuring cup I was mixxing in. That's what put me on direct dosing with measuring spoons straight to the tank. I've seen no problems so far. The fish might get curious but they lose interest when they discover there's nothing worth eating.

    It makes it so much easier and I'm really into easy when it works.

    If you're talking about as you're making them, fill your sink to about halfway up the bottle your mixing in with the hottest tap water you can get. This in turn heats the water in the bottle and makes it much easier to enter the solution.

    If you just mean in general, some stuff does fall out every now and then in mine. A quick stir with a spoon and all is well for the dosing. This happens more in my macros than micros.

    it just occurs with my macros...eventually most of it settles out of solution. I have been shaking it up before dosing. Is untreated tap water okay to use? heating is a great idea...that may help.

    Po4

    Hi,

    The PO4 and Ca are likely the problem. :gw

    The PO4 and Ca are creating an even harder to dissolve compound. :eek:

    You should not need to heat this stuff, shaking is just redistributing the stuff that has fallen out of solution.

    What are you mixing?

    Keep traces in a different bottle than the macros.
