That's one of the main problem in using chlorine in spa or even pools CYA build up. You have to test for it regularly and replace your water once CYA levels is getting high. If CYA levels goes high the cleaning capability of chlorine gets compromised and you'll end up in getting dirty water in your spa. Algae will eventually grow when that happens. Using bromine will be more expensive than chlorine. But the salts can be reactivated into bromine if you add a little amount of chlorine shock. This will help you in the cost department because you're just reusing it. If your spa are located indoors it would be best to choose bromine over chlorine. I hate the odor and the irritation it gives. I buy my spa chemicals from an online seller that does free shipping https://pstpoolsupplies.com/discount-non-chlorine-spa-jacuzzi-hot-tub-chemicals/

For me I would stick with Taylor. They are in the industry for a long time now. So they would have my vote of confidence more than other brands in terms of pool testing kits. The 2006 kit does the job right on the spot all the time: https://pstpoolsupplies.com/taylor-technologies-k-2006-complete-poolcare-dpd-fas-test-kit/ I bought my kit there and they delivered with free shipping.

Chlorine shock should be done once a week to keep the algae out. I also heard about this amazing Puri Pool process which I found in Youtube. Haven't really tried it. Just wanted to share maybe it might help you.
