Am I glad I found this forum ... I'm tired of having the pool store suck the money from my bank account!!!
Sorry for being long winded here as I will try to bring you up to speed on what has taken place over the last few weeks during this conversion.
I have an Inground Vynil pool at 22500 gal, Hayward sand filter and 1.5hp pump as well as an in line chlorinator for 3" tablets. I am adding/converting to a Hayward Swim Pure SWG.
While trying to save money, I have purchased and installed the system myself but the pool store is guiding (raping) me through the conversion. I had purchased (along with the SWG) Monopersulfate to get rid of the Baquacil (at a starting point of 40ppm) and it did a really good job according to the pool store. And have backwashed numerous times and chemically cleaned the sand. The colors where not that impressive ... mostly a brownish grey that dissapated.
Here's where it gets costly!
I started the conversion 2 1/2 weeks ago, and so far have spent over $800 in Bioguard (among others) chemicals. After the first week and a half they had me change my sand stating that the baquacil was still in the filter and needed removed. After the second week I have installed the cell in line and am just trying to get the levels correct before turning the SWG on.
Here are the stats to date:
Shock, shock, shock, $$$, $$$!!!
CYA 53 (after adding on 5-17 with a level of 22)
Total Chlorine 1.7
Total Hardness 267 (probably due to all the calcium based shock, was as high as 299)
CYA 20 (why?, didn't backwash)
On the 18th my pool was back to a greenish Marguarita hue and they don't know why. And have since added algecide at their suggestion. I might add that I have been adding 3" trichlor tabs to the chlorinator throughout the conversion.
I have now purchased a Leslies DPD test kit, chlorine bleach, soda ash, baking soda ... and am trying to do this myself (with some guidance of course). Now being the 22nd, I am getting quite different readings with my test kit ... maybe I am doing this wrong, but here goes.
TC 8-10 (above the highest reading on my test kit of 5, just guessing.)
Added 2 lbs dichlor, 5 lbs low & slow to lower ph to 7.2 and try to get TA to come down.
Have also added a fountain for aeration.
Last night after adding 2 gallons of bleach:
And lastly this morning:
I plan on taking a water sample to Leslies (not my regular pool store) to get more accurate readings tomorrow.
Please advise, and thanks in advance.
