Dilution Strategy for 15 Gallon LC and MA Tanks

[bgreenen]

Over the years, my Liquid Chlorine (LC) and Muriatic Acid (MA) tend to work in lockstep in a 3:1 ratio. So, I plan to install two Stenner 15 gallon tanks with Econ T pumps, for the LC and MA, respectively.

I plan to dilute the LC 1:1 (eg. 7.5 gal LC : 7.5 gal water) and the MA 1:5 ( eg. 2.5 gal MA : 12.5 gal water).

My thinking has three considerations:

1. Diluting the LC will help slow it's degradation due to being a lower concentration
2. Diluting the MA will make it less harmful to all the equipment with which it will come into contact
3. Diluting each such that it creates a 1:1 ratio between the two, allows me to run the pumps for the same length of time each day (at different times of the day, of course), keeping the levels in each tank equal to one another. That way I as I need to fill them, I can do it at the same time and in the same total amounts, making it that much easier for me to remember and do.

Note, the LC tank and pump will be inside the pool pumphouse and the MA tank and pump will be outside the pool pumphouse.

Does all of this make sense? Am I missing anything? Are any of my assumptions or conclusions wrong or misdirected?

Any input is welcome. Thanks in advance!

Liquid chlorine degrades due to temperature and time, not concentration. I’d worry that your 15 gallons of chlorine would just degrade sitting outside in the hot sun/tank.

Most people just make the chlorine on-site directly with a salt water chlorinator as it’s way easier and cheaper. Maybe something to consider.

Welcome to TFP.

How many gallons in your pool?

Where is 94022?

My pool is 20,000 gallons. 94022 is in the SF Bay Area.

If your pool uses the average of 3ppm of FC/day you will use 1 gallon of 5% chlorine per day. That 15 gallon tank will require refilling about every 2 weeks.
