Is there a feedback mechanism that tells the unit the chlorine balance in the pool? Is this a way for me to automate addition of clorine to keep it always at the correct level? Or, just another place to put the tab aside from the the drain basket?

There is a dial on this unit which has a setting from 1-10 If you set the dial on 1 it will be letting the least amount of chlorine to the pool and if you have it set at 10 this would send the most amount of chlorine to the pool. So you can automate the feed of chlorine to the pool but you will still need to manually test your water. We do not recommend placing tablets in the skimmer basket because this high concentration of chlorine goes directly back to your pump and can cause corrosion to your pool equipment. If you do not go with the automatic chlorinator we would recommend at least going with one of our floating chlorinators so you do not damage your equipment you may view our floating chlorinators here http://www.inyopools.com/chlorinators_floating.aspx

How do I know if one chlorinator is enough for my pool?
Reply
The Hayward CL200 or CL220 chlorinator will provide enough chlorine for up to 40,000 gallons of water. You would need to calculate the volume of your pool to determine how many chlorinators you would need. For example, if you have 60,000 gallons then you would use two CL200 or CL220 chlorinators.

What is the difference between an inline and offline chlorinator?
Reply
An inline chlorinator would be plumbed directly inline with the plumbing. For an existing pool, this would mean a section of pipe would need to be cut out to install the chlorinator. An offline chlorinator attaches to existing plumbing by chlorinator tubing (holes would be drilled into existing pipe to attach the tubing.)

I have a really hard time taking the cap off my chlorinator. Is there a wrench that I can buy?

If you are having difficulty removing the lid on your Hayward CL200 or CL220, you can the Dura Grip Lid Wrench: http://www.inyopools.com/Products/07501352020738.htm#parts It fits securely on the lid, making removal a breeze.

I wanted the exact cholrinator. I wanted to get the new cholrinator to fit in the exact spot. This cholrinator was the exact match. Easy to find and exact. Removed old cholrinator and added the new one. Just unscrewing the old one and added the new one. All replacement parts came with the part which made the replacement super easy.
