Hi everyone, been reading here the past few weeks and gathering information. At the end of this week, I'll be moving to my new (to me) home that has a pool and spillover spa. It is an inground concrete pool, estimate about 10-15K gallons (maybe more), spa is about 500 gallons. It also has a waterslide that is built into an artificial rock that houses the pump, filter (sand), and electrical equipment down below. The pool has been drained as well as the spa, I made a deal on the contract, so I will be filling and starting up the pool myself. Is it a good idea to start up the pool using pool store shock and chlorine pucks, then switch to BBB when the CYA gets to where I want it? I don't have a SWG, chlorinator, or heater. Is there anything I should be careful of when starting this pool up? Sorry about all the questions, but I want to make sure I do this right, the first time
