2 part Dosing

MrFantasy · 10/21/2015, 09:06 AM

I bought BRS 2 part system. I started when my cal was at 320 and alk was at 7. It only took two days of doing 20 ml a day to bring up my alk but I started with 60 ml doses of dry calcium chloride that I mix in a gal jug. after two days it only got me to 340 so the next day I doubled it and it only got me to 350. my question is How ml does it take to equal 50 ppm or is that not a possible question when cal is that low? I want to stay in a safe range of daily dosing but I also want to get it up to at least 400 - 420. I don't know if since it was that low my rocks are absorbing it faster than I'm putting it in. I have a total water volume of 125 (90 gal DT and a 75 gal sump) I have about 125- 150 pounds of Live rock plus fish and corals. I use ro/di water and my last water change was two Sundays ago.

To raise the calcium from 350ppm to 420ppm in 125 US gallons of water it will take 895.5ml of BRS 2part Calcium Solution. You can use the reef calculator or their website to find this information (See link below). They recommend that you do not raise the calcium level more than 50ppm per day. So, you would need to space that out over a few days.

I'm not an expert as I've just started dosing but I think it's tough to raise alk and calcium in Mag is low. What is your mag at? I was having minimal success but when I started dosing mag everything seems like it's working better now.

I only use dry calcium chloride for calcium its one part. the mag is a 2 part but only a one part for cal. and i used that calculator but if you use dry calcium chloride it doesn't give you the ppm.

can I go by this 895 ml and dose half that and not be going over 50 ppm?

That's kinda low, actually. Aim 1300-1400. A lot of folks run 1450-1500.

The 895 is "all in one shot" jump from 350 to 420, which is a jump of 70. So yea, half that should only give you ~35ppm jump.

Personally, I would do one shot today (~450mL) and check your values an hour or two later. Then repeat tomorrow, and check it again on day 3 to be verify you are where you want to be.

I'd buy a bottle each of the of Kent tech-cb part A & B, or any other 2 part solution that comes in bottles.
Use the reef calculator http://reef.diesyst.com/chemcalc/chemcalc.html
First, dose enough mg to get your mg around 1350.
if it's too much for 1 day, split it and take 2, or even 3.
Once that is done, dose enough Kent (or whatever) to get your calcium to around 420 and your kh to around 8.4.
It's concentrated and much easier for making level adjustments.
Once your levels are good, check kh again in 24 hours.
Whatever it's dropped, use the reef calculator again to calculate how many ml's of the BRS solution per day to dose.
Set your dosers for that amount.
Use the Kent to get your levels back up, boom, you are dialed in.
You may have to make slight adjustments for a few days, but that's basically it.
Using your dosers to get to the correct levels is a major PITA, buy some bottles for adjustments.

I was just trying to get everything close to normal before going to higher levels. And on BRS 's Calculator. It called for 4.2 oz for dry calcium chloride so I was a little weiry of putting to much in. I'm not sure if they meant to measure out that much dry powder and mix with water or to just use that much after mixing
