I have not seen the pool opened, only the pictures. We are going to write in the contract that the pool be brought up to working and clean. Does it look like some sort of staining in the deep end? Is that something the current owners are going to be able to "fix" without costing alot. Also, is there anything I really need to know about now? (I did have an IG vinyl pool last summer.) I saw the filter tank it it's a BIG stainless steel thing. I assume it's pretty old... The home was built in '75 but I don't know when the pool was built. Anyone know much about those? Also, should I put in the contract that I want the CYA test to read anywhere between 30-50 and NO HIGHER. It was a pain in the you know what to deal with a CYA level that was WAY WAY too high last summer and I would prefer they take care of any drain and refill **** before I take over ownership. Wish me luck! We are putting an offer down this evening or tomorrow.
