Goes with the weather. Here in Canada, pools are closed about 5 months a year, drained every year too. Makes Cal-Hypo a reasonable choice.Melt In The Sun said:It's rising because as water is added, calcium is added, which stays in the pool when the water evaporates. So calcium continues to build up.
For example: almost one year ago, my CH was 350. My fill water is 210. In Tucson, we have about 80 inches of evaporation per year. My pool averages ~48" deep. So in an average year, a little less than two entire pool volumes evaporate and are refilled (leaving their calcium behind!). My pool is now at about 650 CH, with not a single granule of cal-hypo or calcium chloride added. Gotta love Arizona!
Thanks! So, the main solution is the drain and refill I guess? Kinda hate doing that with CA already low on water. I'll keep checking it.simicrintz said:Yes, new plaster will increase the CH levels as it cures out. Keep an eye on it and don't let it get too high!
The "standard" solution is to drain and refill (although you only get back as good of water as the water company provides you ), as R/O is not available in all areas yet. Hopefully that will change one day, especially in drought areas (like California).NoPool4U said:Thanks! So, the main solution is the drain and refill I guess?

A submersible pump. Or hook a hose to the backflush port on the filter and let 'er rip. If there's a significant elevation difference, a garden hose or two used as a siphon will empty things out.modog said:I don't really have a way to drain. I was going to just put the water hose on the pool floor and let it rip. The overfill drain leads to the back of my property. I assume this will work? How else can I drain the pool?
The backwash outlet is usually at your filter, so the manual to the filter will tell you how to do it. The only thing you need is a backwash hose (sold at any pool store) to connect to the backwash outlet and then route it to a drain. You basically turn off the pool pump, turn a handle on the filter and turn the pump back on and it will pump the water out of the pool. The backwash is normally used to clean the largest debris off your filter.modog said:Richard320 and mas985,
Can you elaborate on how to pump the water out? Also, there was mention on connecting the hose to the backflush port? Can you help me understand how to do this? Also, how to use a hose as a syphon? I was just going to put the hose in the bottom of the pool and turn it on. This won't work?
