I build myself an Arduino powered chlorine injector. Because FC will be fairly constant, do I want to use the TFP calculator’s values for a swg pool or a non-swg pool?

I have a 25000 gallon pool and the cya is low - 20ppm. According to PoolMath adding 16 oz of dichlor raises CYA by 2.4. The dichlor I have is Clorox 4 in 1 pool shock which, on the label, is 58.2% dichlor. Am I correct in assuming that 16oz of this product will raise CYA by 2.4 (the value...

When I moved in to my new house, my pool had a CYA of 120 and I had algae problems regardless of the FC levels. I drained the pool twice to get the CYA down to 40 and switched from expensive pool store trichlor to pool bleach. Never had a problem since. You may want to drain 1/2 your pool to...

I too didn’t like the idea of relying on the gcfi and being a gasket away from electrocution with 120 volt bulbs. Search the web for pool electrocutions and you will see what I mean. I replaced by halogens with the highest wattage 12v led I could find that had a e26 base (standard base for a 120...
