You might know me from the thread, "ImPower motor controller not working according to manual" but probably not because I don't think anyone read that thread.
Anyway... we inherited our in-ground plaster pool when we bought this house in 2013 and for the last couple of seasons I have been using 7-way test strips and HTH unstabilized granular chlorine along with the HTH + and - products from Walmart. I have not had trouble clearing the pool in the spring and keeping it clean and clear throughout the season - by sheer luck I suppose.
I plan to switch to the TFP method and I have a TF-100 waiting at a receiver across the border (Canadian, so hoops must be jumped through) that I will pick up tomorrow.
My question is this: Since I have 2/3rd of a pail of HTH unstabilized granular chlorine, can I still use this as part of the process? I think from my reading that using this raises the calcium hardness as that is what the chlorine is bound to in the granules? Can I use PoolMath to calculate how much granulated chlorine I would use instead of bleach/liquid chlorine?
Or is this just going to mess up the TFP process?
