One of the main questions customers ask when they are deciding to buy a chlorinator is, “How do I decide if I need an inline or an offline chlorinator?” Well, chlorinators play an essential role in keeping your pool healthy for your family. However, not all chlorinators were created equal. You need to consider the best option for your pool and family.

Hi. I have a 24,000 gallon inground pool, currently with an inline chlorinator (Pool Frog). It's old and needs to be replaced. I could install another inline chlorinator (like a Hayward CL200), however I am better off with an off-line model so I can just have straight 2" PVC to my returns vs. the restricted inner diameter of the CL200? ThanksReply

If you want a less interrupted flow through the system, I would choose the offline. Just to make you aware, there is the Inline Hayward Chlorinator 2 Inch Slip, but the vessel's ports are the same as the standard CL200.Reply

So, even though the Haywards have 1.5 or 2" inlet/outlet pipes, both have the small (maybe 1") internal diameter opening that I see inside the CL200? I don't understand why anyone that understands this would want to install an inline chlorinator, when the offline allows continuous unrestricted flow through whatever other pipes (2" in my case) are in the system. Thanks for your help, I'll be looking at an off-line installation..Reply

I have an above ground 24ft x 54 in pool. I have an ozonator that works on my pool as well. No heater just pump, filter and ozonator. What would be the best option for my pool, off line or inline?Reply

As we mention in the guide, the main factor on whether to use the inline or offline chlorinator is if there is enough space on the plumbing line to mount the inline. Other than that, it is personal preference. So, if you have enough space, you may use the inline chlorinator; if you do not, use the offline.Reply

Do you suggest the Rainbow 320 chlorinator or the Hayward CL200 Chlorinator?Reply
InyoPools Product Specialist Robert M. Posted: 10/23/2018
Hello Patrick - I would recommend the Rainbow 320 over the Hayward CL200 chlorinator. The lid on the Hayward chlorinator becomes very hard to remove. The reason for this is that the o-ring expands and makes it very difficult to remove the lid. The Rainbow 320 does not have that problem.Reply

I would suggest the Rainbow 320 chloorinator as where the pipe connects underneath the chlorinator is 2" in diameter where the Hayward CL200 reduces to about 3/4" which really restricts water flow and increases pressure in your system.Reply

Anonymous (chlorinator) - The standard Rainbow 320 Inline Chlorinator will work well for your size pool.Reply

Hi. I have enough pump house room to fit an inline chlorinator but I am not sure of the size I require. Our pool will be 10.7m x 4.2m with a sloping bottom. Shallow end is 1.0m & deep end is 2m. I am looking at the Rainbow feeders. Can you tell me which one I should select please. Thank you.Reply

Chlorinator - Many people use the Rainbow 320 Inline Chlorinator for your size pool.Reply

We can use a in-line chlorinator (3" tabs). Our pool is in ground about 9000 gal what size do I need?Reply

Nicely done but when running the spa and pool returns at the same time you'd be heating your pool water. Is this the set up most people use?Jim

Rpswat - For your size pool I would recommend a high capacity chlorinator like the Rainbow HC-3315 High Capacity Auto Feeder. It will treat a pool with up to 97,600 gallons of water. This size gives you the capability to super chlorinate during heavy use in hot weather.Reply

What options are available to add a chlorinator to a 56,000 gal pool?Reply
