brs 2 part

[myrjon]

just recieved cal alk and mag kit.
instructions on brs site calculator confusing
1 ~2 part calcium solution
2 ~ dry calcium chloride crystals
3 ~ alternatine 2 part calcium solution for lowering ph


i chose #1 right
cal now 385 need to go to 420


says I
Need: 429.8 ml
14.5 fl oz
85.9 tsp



IS THIS RIGHT

Yes, you want to make solution 1....and with BRS, I believe they use an anhydrous calcium chloride, so I believe it's two cups calcium chloride to one gallon of RO/DI water. Note, it is an exothermic dissolution, so it will get slightly warm while it dissolves.

paul. solution is made .Just questioning that i was to use 2 part calcium solution on the brs calculator . just seems a lot.

If you are adding 2 part you want to do the bump up to desired amount over days. Too much too fast will cause stn at base of sps.

Zippy had some good advice about slowly raising your numbers. Note calc isn't as damaging as alc as far as quick rises in concentration.




Here's what I'd do.....385 isn't that low.....I'm assuming you are daily dosing alc and calc. I'd slight increase that dose of calc to slowly bring your calc number up. I use dosing pumps and now test monthly. If I notice my numbers aren't where I want them, I do just that....slowly increase or decrease the volume I'm adding to the tank to slowly bring them to were I want them. Hope that makes sense.

Alk 1.7 fl oz
Cal 14.5 fl oz

BRS uses Randy's recipe for two part, so use this calculator, fill in the blanks for your system, use Randy's recipe #1* from the drop down menus for both calcium and alkalinity and magnesium(if necessary)sections to get the dosage of each.

* Recipe #1:

2 1/2 cups of calcium chloride mixed into a gallon of RO/DI water(calcium solution)
2 cups of soda ash mixed into a gallon of RO/DI water(alkalinity solution)

If you got the magnesium chems:

5 cups magnesium chloride and 3 cups magnesium sulfate mixed into a gallon of RO/DI water(magnesium solution)

I would make sure your Mg is between 1200 and 1400 ppm before dosing the Ca and Alk chems.

Don't elevate your Ca more than 50 ppm per day, your alk more than 1.5 dKH (.5meg/l) per day, and your Mg more than 100 ppm per day.

If you need to start dosing, I would make sure your SG is where you want it(1.026), keep your regular WC schedule, since this is where you're adding much of your Ca, Mg and Alk. Use the solutions individually to get your param's where you want them, then start testing to get your daily demand.

good info jim. like Randy's recipe #1. this helps cause i checked out that calculator too and did not know what to choose.
