Chemilizer Chlorine Injector

Having decided that I need to get away from Trichlor chlorination I have been looking at the alternatives. I have just found this product www.chemilizer.com and wonder whether anyone has any experience or views on it

Very interesting.

Found it for $371.99 here at Inyo pools so they must believe it is appropriate for pool applications.

It's not electronic which means simpler and more reliable, but also precludes the use of any kind of electronic dosing control.

You can't get electronic dosing but as it injects a precise dose per hour and only works when the pump is on so it is easy to work out what does you will get.

The $372 doesn't include a tank, and it still requires lugging chlorine bottles.

I finally swapped to salt for about $900 and I really like it. The only situation I would imagine not wanting an SWG is where the salt water could damage exterior hardware or stonework. But in this situation I would probably lean more towards this peristaltic pump. It's only a bit cheaper and you'll need to connect it to some kind of timer - or maybe the pool pump timer - but you won't need to divert any flow from the pump, it's a lot smaller, and it works against the pump output pressure up to 100 psi so I see it as a bit more exact dosing.

Hey thanks for this, it looks just right for what I would like to do. Richard, have you ever considered using one of these? Apart from the obvious drawback of having to lug chlorine around it looks like the perfect solution.

One other thing I wanted to mention/ask with the Chemilizer is whether or not it shifts dosage during a run.

I had set up a drip system using a 5 Gal camping water bag from Walmart and some tubing and connectors from Home Depot. The whole thing cost maybe $20 but I discovered that as the weight of the bleach in the bag decreased, so too did the drip rate.

I wonder does the Chemilizer change feed rate if the pump drops output (as the filter backpressure increases), or if there are any other dose shifting problems.

I think if I had a large pool and no budget limits and still didn't want an SWG, Inyo pools has assembled a complete system including sensors for pH an ORP (to measure cl) that will dose bleach based on measuring, and using two each of those pumps as dosers for muriatic acid and bleach and two tanks for the chemicals.

On a budget I would use the one pump, a 5$ camping water bag from Walmart (btw, this bag collapses when empty so when properly connected to the feeder pump it keeps the air out of the bleach, and 5 gallons is a lot of bleach). Once I got the flow rate figured out and set I would use a pH tester to monitor the acid demand as needed.
