Dosing pumps and solution question

My system uses 0.117 meq/l or 5.85 ppm or alkalinity per day. This comes to 0.275 teaspoons per day. I have been adding this to my ATO bucket that empties every 10 days. As such, I add 2.75 teaspoons of alkalinity each time I fill my ATO bucket. this has kept my levels fairly stable.

I have an opportunity to grab a Aqua Medic dosser and I am wondering how to mix a solution to accomplish this same goal.

The peristaltic pump doses at a rate of 0.8 gal/hour.

Thank you for the help.

 

Is this right?

Pump rate= 0.8 gal/hr
1.25 hours= 1 gallon
1.25 hours/30 days (1 month supply of solution)= Dosing for 2.5 min/day
Tank use= 0.275 teaspoons of baking soda/day
1 gallon solution=8.25 teaspoons baking soda

 

I know there are some mad scientists out there. Crunch some numbers!;D

 

I'm a little confused, you said 0.8 ml per hour, then you said 0.8 gph - big difference

Assuming you meant 0.8 ml per hour, you would need 1.35 ml to equal .275 teaspoons

If it pumps at .8ml per hour, it needs to be on for 1.7 hours per day, but that seems like a very long time - you might have meant 0.8 ml per minute (my BRS pumps do 1.1 ml per minute) so in that case, it would be 1.7 minutes per day

That make sense?

 

Sorry, the list the flow rate at 0.8 GPH or 50 ml/min.

Pump rate= 0.8 gal/hr
1.25 hours= 1 gallon
1.25 hours/30 days (1 month supply of solution)= Dosing for 2.5 min/day
Tank use= 0.275 teaspoons of baking soda/day
1 gallon solution=8.25 teaspoons baking soda

That comes to a solution of 0.03 gallons or 4.2 ounces per day.

 

How do you all figure out your dosing mixture? Maybe I am making this too complicated?

 

After some more research I have concluded that this pump is geared more for an ATO system. 53 ml/m is too fast.

 

I use aquamedic doser. I use BRS materials and I make the solution per their instructions.

I did some baseline tests on the doser to see how much output it was giving. I then figured how much I need to manually dose each day (already knew that bc that was what I was doing b4 I got the doser). Then compared the two numbers to come up with a rough 'seconds' value to run the doser.

I took a baseline test of my water then installed the doser at the above 'seconds' value. Measured daily and it took about 3 or 4 days to dial it in perfect. Rock solid stable ever since (several years).

I'd recommend putting Aqua Medic dosers on a UPS. I use an APC ES 350.

EDIT: BTW I run alk something like 23 seconds at night and Ca something like 22 seconds around lunchtime.
