I'm a new home owner with a beautiful pool but it has so many gadgets, I don't know what to do. I can't afford a pool cleaner so I'm trying to maintain it myself. The house was vacant for years so there aren't any manuel so I google a lot & use utube. I know how to keep the pool clean, shock it, add chlorine tabs, & algaecide. The pool is rectangular (4- 8ft deep) with a spa. It has 2 spa blowers, Lite 2 pool/ spa heater, a Triton II sand filter, & an Aqua rite electronic chlorine generator. I trusted the agent when he told me all of the pool equipment was functional, he turned on a couple of switches to prove the water was flowing in the pool & the spa jets were working so I took his word. Well, the heater shows a little serviceman icon, 1 spa blower works, & the chlorine generator states, check cell. What should I do because I have a feeling this will cost me an arm & a leg!! Please advise.
