My CH level was 410 last year. Now it is at 460. How high is too high? What are some ways to bring this down. I tested the refill water and it is 210. The PoolCalculator says to refill 63% of my pool water. Any other ways to do this?
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.
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?
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?
