    Leisure Time Renew vs. Replenish for shocking hot tub?

    Holy cow! My head is swimming. Thank you all for the very detailed information. If I'm understanding all this correctly, both chlorine and bromine are equally effective sanitizers for hot tubs. The main differences are that chlorine is less expensive but requires more frequent applications...

    Leisure Time Renew vs. Replenish for shocking hot tub?

    While my spa has the mineral cartridges (silver ions?) and the ozonator and was advertised as a low-bromine system, I don't know that I put much faith in that and wasn't planning on relying on just the ozone/silver system to keep my spa fresh and clean. In fact, I bought extra bromine (Leisure...

    Leisure Time Renew vs. Replenish for shocking hot tub?

    Thank you all very much for your very detailed responses. It is greatly appreciated! Having been a saltwater aquarium owner for 10+ years, I'm no stranger to constant testing and adjustment of water chemistry. Because of my SW experience, I've been a big fan of LaMotte test kits for a long...

    Leisure Time Renew vs. Replenish for shocking hot tub?

    Yes, we were sold on the bromine spa with thought of being "chlorine free." My wife hates the smell of heavily-chlorinated pools and spas. So we went with a bromine system thinking we would avoid the chlorine smell. I'm trying to learn all i can about the system now.

    Testing bromine levels in hot tub. How long to wait?

    I have a Marquis e750 hot tub. I use a Lamotte ColorQ test kit to test my water chemistry. When I test for the bromine level, I add the 5 drops to sample and invert the tube several times before inserting into the ColorQ reader. My bromine levels always test really low; usually less than 1ppm...

    Inflatable hot tub during cold Chicago winters?

    My wife and I stopped in at a pool/spa dealer over this past weekend to see if they have any inflatable or portable spas in stock. After talking with a very helpful and knowledgeable salesperson, we are now trying to decide if we might be better off just purchasing a regular/permanent spa to be...

    Inflatable hot tub during cold Chicago winters?

    Hi! Brand new to the boards here, and I signed up specifically to research using an inflatable hot tub in the winter. My wife and I really hate the cold winters here in the Chicagoland area. So much so, that we were going to move to Florida. Significant logistical issues prevented the move. So...
