Hello Everyone.. I recently purchased a home and it came with a Spa, from the get go, looks to be a LA Spa Quest, older model, early 2K timeframe Anyways, it has not been used in at least 2 years and has been sitting there, empty (no water) It needs a REAL good cleaning both the shell and the internals.. I am going to run this as a Salt spa, so I would like to get this CLEAN, inside and out and replace any parts that needs to be replaced before I jump into getting the salt water setups.. This is my first run with a SPA, so any help would be great.. Also, question on the "Spa Purgers" I know there is a few like Ahh-some, Spa Purge, etc.. Whats the going recomendation and when you use a purge product, do i need to get the water balanced (PH & AL) before I start the purge or just fill it and go? Thanks ahead of time..
