Dosing alk, cal, and mag

[Chiefmaster30]

Can anyone help me out with any advice when dosing these 3 main elements. I'm currently dosing seachem reef fusion 1 and 2 and seachem's reef advantage magnesium. I have a 120 gallon tank with a 30 gallon sump. I'm dosing 23mg of 1 and 2 and 6 teaspoons of the mag. Daily. My question is when I reach the levels I'm wanting to reach do I continue dosing the same amount or do I cut the dos? I'm assuming I would cut the dose or dose less often but.... next question: what do I cut the dose to? And how often? Thanks in advance!

Tank is 2 yrs old. All my parameters have remained pretty stable besides occasionally dosing mag and calcium until a couple weeks ago I tested and everything was way low. As in:
Cal 340
Alk 7
Mag 1100

You will need to match the dosing to the demand, at least to the demand for alkalinity It is the main one to monitor for over or under dosing. :)

Anyone use the Prestone to make Calcium ? I want to hear opinions and how much you used to make 1 gal?

I've been using Prestone Driveway Heat since 2008. Because it has less associated water than Dow Flakes, you only need 2 cups per gallon. Note, when mixing with water, it's exothermic......it's going to get fairly warm.

thanks for the info. how do you mix yours?

I use a one gallon jug (old vinegar jug), and using a wide mouth funnel I dump in two cups of Prestone. Fill up the gallon jug with RO/DI and immediately cap and start to shake the jug. I do this immediate shaking because I'm concerned about the localized heat produced in the bottom of the jug.

Google randy's 2 part. 64 oz Epsom salt with enough water to make a gallon

You can dose just Epsom salt, however you can end up with an excess sulfate problem. Better off following Randy's recipe 1, 3A.....3 cups Epsom salt plus 5 cup magnesium chloride. For magnesium chloride you can use Mag Flakes (an ice melt product) or purchase from BRS.


FYI, HERE's the link to Randy's recipes.
