Good grief I am only *minutes* from having my pool finished and just can't seem to get there from here! My PB finally installed the liner (waste, apparently the floor was still wet when he did this, therefore the reason for the vacuums going and no fill - at least that's what *he* said) and we finally started filling the pool on Friday. He told me to let it fill to just before the bottom step, then stop it and he would be back on Sat. to finish the liner and I could finish filling it. Well, shocker of all shockers, he hasn't been back since! We have had plenty of rain, but not the entire time. I didn't call him today because starting tomorrow the summer water discount automatically kicks in so my fill will be cheaper. My question is, here the pool is only partially filled with no chemicals in it. How long before the algae starts?? Is there something I should be doing to keep that from happening?? I will be started with the Bioguard start-up for the Mineral Springs system in case that matters. Thanks bunches!
