Thanks every, and Simonc for all your help.
Well we looked at the tub a bit more last night, as well as the chemicals we had. We have the small 1" chlorine pucks for spas. We have a bottle of the ph test strips and we also have a bottle of another chemical which claims it will make your water clear.
The tub is a beachcomber and it appears to be a bit older. In the immediate left corner from the deck is the nameplate and the corner is flattened with what appears to be about 5 drink holder spots. There's 2 buttons which are a bit firm to press down, 1 for the 1 lights, 1 for the jets. There are also 2 large flat chrome dials which I am not sure what they do. At the side of this molded drink holder corner is a cover plate where it appears a filter and the plate are half dangling off and there a bit of surface rust on the plate. So ya, this thing needs a bit of TLC. There is also a filter sitting at the bottom of the tub. It looks like a cylindrical air filter to me honestly. We also found the floating chlorine puck dispenser.
The house was on the market for possibly 6-8 months so I have no idea of when it was actually used last. I would love to drain it to start anew, but it's cold and I feel I'm too new to tubs to tray draining it in these temperatures.
What should we do in the meantime? We'd like to get the filter parts out of the bottom and check all those out.
Thanks again everyone.
