Chlorine Tab dispensing

I always use liquid chlorine (per TFP) except when on vacation. Then I use the floating dispenser with 3" tablets (and closely monitor my CYA). However, the dispensers seem too slow. I even use two floaters for a 26K gallon pool and they hardly keep up with demand. Any suggestion for faster dispensing when using the floaters??

Unless you have an inline which forces water across the tabs, floaters are kind of tough. I guess you have no one trustworthy in the area who could add a little liquid for you and check the skimmer while you're away huh?

Some floaters have adjustable vanes to let in more or less water. If yours do, open them all the way. If they don't have such vanes, maybe drill some holes in the floaters to get better flow.

I have been searching, and I thought it a great business opportunity, for someone to offer service only when on vacation. I would pay many times the usual 1 month rate myself for this service, but haven't found anyone yet :)

Back in the day, we could find a good neighbor kid and give him a few bucks to babysit the pool. They would be thrilled. Nowadays they won't let go of the gaming controller. :(

That's a great idea! Sadly, Saratoga is a bit too much of a drive from here. I know we have members in Santa Clara county, though...

SWG is really the best option. If that's off the table, then a Stenner Pump would be another option. You could get a pump for under $300 and DIY the tank. If you only use while on vacations, you'll get several years of use out of it.

If you're really comfortable using tablets and rising CYA is not an issue, you could use a 5-gallon bucket with a lid and drill several holes around the side and top. Add some weight to it and you can hang it near a return. Or, add some foam to the lid and make your own floater out of the bucket. I've never seen it done, but it would be fun to see.

Probably a stupid idea, but outside of using more floaters, I'm out of ideas.

Best of luck!

Tie the floater near a return. When the pump runs, the floater will typically get picked up in the water stream, which will dissolve the tablets quicker.

OK thanks, but question on chlorine feeders like Stenner Pump. I have been told to not put pucks in skimmer due to build up when pump is off then sudden release. Wouldn't these pumps have the same issue (of course I know very little about these pumps)

A Stenner pump is a small chemical dosing pump. They actually never touch the chemical. They use rollers on the tube carrying the chemical to push it through the tube.

The Stenner's dispensing tube is plumbed into the return side of the plumbing at the pad. The Stenner should be set to only dispense when the pool pump is on.

Hmm, trying to visualize. I cannot find a good picture of a Stenner Pump , but other feeders look like they are large tanks to hold tablets than have and in/out tube for the water, with dial control for concentration. Sam idea? soem or only about $100, but is Stenner better?

oh I see, the tabs are no "sitting in a tub of water" to then dispense when pool pump engages, but water only runs over them when pump is on

Yes anchoring the floater in front of a return and opening up the cage speeds up decomposition but a warmer water temp seems to be a bigger factor. SWG is the best tech solution.

LC would be great, but more expensive. If I only use the chlorinators with tablets when on vacation like I do now and monitor CYA, any disadvantages to the auto feeder that use tablets?

That is a viable option, though usually one chosen by people that already have an inline chlorinator and are trying to save money. Remember that dissolving the pucks faster will increase the CYA faster as well (compared to the slow increase you are seeing with the floaters).

I definitely second the idea of a SWG or Stenner pump. SWG is higher upfront cost but pays for itself in decreased LC use. You'll see many on the forum saying Salt water chlorine generators let them vacation with peace of mind that the pool won't be a swamp when they get back.

Worried about salt levels? My salt was already 1/3 of the way there when I converted. $70 in salt later and I was at the appropriate level (less than 10% sea water levels). No one that has been in my pool can tell the difference in salinity.

With a proper test kit, regular monitoring and a good understanding of how added chemicals affect your water chemistry you are in control.

Tabs are acidic, so you would need to monitor pH.

If you have a heater, you would need to add a check valve before the tablet feeder to prevent acidic backflow into the heater. A Jandy check valve runs between $50-$75 if you can find one in stock. I waited about 5 weeks before cancelling my order back in late March.

You would need to run some tests to calibrate the chlorinator dispensing rate to meet FC demands.

For your pool, each dissolved tab will increase CYA by 1.3 ppm. Something to keep in mind as you move forward.
