PoolDoc, I just ordered 3 of the Unicell B cartridges off the Amazon link. Thank you, for this experiment to work correctly, I MUST have the genuine Unicell article. I am off to buy two new 5 gallon buckets with lids that those carts will fit into easy and for the whatever of it, practice with the Intex cartridges first using the cleaning system you suggest. 50 bucks for superior cartridges and the small extra work to clean and maintain them is worth the effort to keep everything small and simple for me. Give it a couple of weeks and I will report back as to the difference between the Intex cartridges and the Unicell ones and how they both work being cleaned.

Do you recommend I just use the normal garden hose sprayer to clean the cartidges off or is it worth the few dollars it costs for the "official" cartridge sprayers worth it?

I need to appologize to you because just a little more effort on my part and education has got me realizing that the Intex folks while not lying about their system, my be reverting to over simplifying things. If their replacement cell is made of copper (and that's what it looked like to me when I was giving it a quick look a couple of weeks ago), then their SWCG system is using copper ionization to make the chlorine from salt. I did not realize that the expensive systems used either a plated material or strictly used exotic metals to keep the copper out of the water due to the blonde hair issues while converting the salt to chlorine. So again, I may decide it is worth my 57 bucks to order one of the replacement cells so that not only myself but everyone here knows exactly what this system is and decide to use it or keep strictly with BBB.

Looks like Wednesday until my Taylor 2006 test kit will be at the house.
