My pool gets covered with a solid cover. I'll keep it open as late as possible until the temps are in the 60s.
The closing kits that are sold at the pool store include a stain preventer and a non-chlorine floater. I've used this in the past but, like most other pool chemicals, do I really need to use this?
Also, how do I prevent algae from growing in the spring before I take off the cover? Do I remove the cover a bit and pour in some bleach or is there an easier way to maintain the water before I take off the cover?
