    BBB Method + 3" Tablets?

    If I'm wanting to use the BBB method, do I still need to buy and use the 3" tablets in my chlorinator? Sorry if this is a dumb question!

    Nope, because they will drive up your CYA. Liquid chlorine/bleach/Clorox takes its place.

    No, you don't have to. We don't generally recommend using chlorine tablets, though there are occasional uses for them.

    There are no dumb questions. We all started out not knowing the answers. The way to learn is to ask

    Awesome, thanks guys! I still have a few tablets left, but I'll look forward to NOT having to ever buy them again!

    Do you know where your CYA level is at right now?

    i'm trying a hybrid approach where i use my 3" tablets only from may-september (5 months) and bleach the remaining 7 months in hopes of controlling the rise in cya.

    That could work if you have a DE/sand filter and backwash a lot and/or we get good rainfall here in SE Texas.

    I have a cartridge filter and with last year's drought I hit a high CYA number pretty fast using 3" tabs. I switched to a SWG within a few months after start up. So far, I've had a very good experience with my SWG.

    Tablets are "bad" only if you throw them in blindly. BBB is about understanding what you're putting in your pool and why. As long as you understand the Chlorine/CYA relationship, and don't let your CYA get out of control, there's nothing wrong with using stabilized chlorine.

    As another data point, I regularly keep 3" tabs in my floater in the pool. Helps maintain chlorine levels as I don't test all that regularly and don't swim all that often either unfortunately. We have lots of rain here in South Florida so I am usually draining a full pool and that helps keep the CYA in check. I also have a rising pH issue due to my spa spillover and the acidic tabs help control that issue as well. So, as mentioned above, BBB is about understanding what you are putting in your pool and why. For me, the tabs are a great solution and solve several issues.
