Got an Intex 15'x48" pool. I used to have some links saved with info on opening, chlorinating the pool and such, but seems the link I saved are now gone. One of the links I lost and can not find is how to open a pool and took you through each step. This process I had mentioned using either dichlor or trichlor, 10 oz for 3 night straight to get the chlorine level and CYA level high enough. My question is, which one, dichlor or trichlor? I found both in granular and can't remember which one to use.
