Hi all, I can't get the calculator to work on my phone so if you could advise, I'd appreciate it! I'm a total newbie with a 15x48 Intex metal frame currently running 1000gph cartridge pump. My 2500gph arrived today but much to my surprise did not come with all the parts needed to install, so I had to order these parts (spending more on them than I spent on the pump!!!) and they won't be here for a few days. So I'm stuck with the crappy pump for now. I had a green pool for a few days and have been adding a gallon of bleach a day to tide me over until I got my testing kit today. I have the Kem-Tek granules coming Tuesday. I know I need to raise my CYA but what should I be doing in the meantime until the Kem-Tek arrives?
