TA was off the charts...CH never got a good reading on b/c as I stated several times in the post It never got the color it was supposed to change and I was so busy trying to get the pool clear I was told to not worry about it. Last yr we opened up the pump/filter, as I stated several times in post, and put in new sand. We put in new sand b/c prior to last yr pool season we had algae but managed to clear it so someone suggested we put in new sand....so we did. Then this yr prior to opening up the pool, we checked the pump/filter and the sand WAS NOT channeled back in May of this yr. This had to just happen btwn May, after it was open and running to now. We take apart our filter/pump and store it for winter every yr so if it was channeled in prior yrs we would of seen it. This is the first and other yrs the pool was fine even if we did get some algae it cleared.
Sand/filter top:
Model # Sp0714tx Hayward vari flo XL Valve Serial # 21120901006272064 the bottom that holds the sand holds 100lbs of sand
Pump: Serial #140083m There are rust spots so some of the rest of the info is hard to read in areas but it is a one horse power pump hayward Power Flo LX pump and I think the Model # is Sp15102 (could be a z but it is hard to read with spots on it) 1xbc. This is the pump/filter we bought with the pool at our pool store.
