I recently let my pool guy go and I'm in the process of balancing the water. First I found that the TA is low (40ppm) so I'm addressing that by adding baking soda. Our pool has always needed to add MA to combat high PH, and I think I just discovered why...
Next I noticed that I had absolutely no CYA as we have a SWC and our pool guy obviously didn't think we needed it. I am addressing that by adding CYA.
I'm now in the process of trying to figure out how to reduce my CH which is at 800.
I know the foolproof method is to drain the pool, and refill with new H20. I tested my tap water and the CH is at 350. So my plan would be to purchase a hose filter to reduce calcium, metals, etc.
Here's my idea - I have a spigot on my pool equipment between the pump and filter. Can I hook up a hose and run the pool water through the inline hose filter over to the pool? My thought is that it would filter out alot of the CH and any metals.
I was thinking it may be easier than draining an refilling with new H20, but I'm not sure how the other chemicals will affect the ability of the inline hose filter (ie. Salt, Chlorine, etc)...
