macgd016 Posted November 22, 2015 Report Share Posted November 22, 2015 I have a pool at my holiday house and I wonder how practical it might be to keep the pool closed and covered through to June. I suspect this has a lot to do with water temp so its worth saying that by June the pool will normaly be in the 20C's. Quote Link to comment Share on other sites More sharing options...
chem geek Posted November 22, 2015 Report Share Posted November 22, 2015 As the water warms up, the risk for algae growth increases. It would be better for you to open up earlier when the water is colder. If you don't do that and get an algae bloom, you can deal with that though it will cost more in chlorine to get rid of it. It's far less expensive to prevent a problem than to fix one. Quote Link to comment Share on other sites More sharing options...

Hey I was going for the exact same thing. With increase in temperature the risk of algae rises. I would like to add something here not only will the pool become green or black, it will rather smell badly. And Black algae is the most difficult to deal with and hence you should open up your pool a little sooner to avoid the whole routine.

chem geek Posted May 18, 2016 Report Share Posted May 18, 2016 If you maintain the proper FC/CYA ratio and have decent circulation, you won't get green or black algae, period. If the FC/CYA ratio is 7.5% or higher, then chlorine will kill algae faster than it can grow regardless of algae nutrient (phosphates or nitrates) level and temperature. The FC/CYA ratio is proportional to the active chlorine (hypochlorous acid) level). Quote Link to comment Share on other sites More sharing options...
