    Incorrect birthday

    I noticed that my birthdate in my profile is incorrect. I can't find any place to change it. It appears that the forum flipped the month and day around is is it was a European date format. Birthday should be June 12th, but forum profile shows December 6th.

    Tapped on ice, liner split.

    I did something really stupid today, and had no idea that the result of my actions would be so catastrophic. It has been rather cold the past week in Minnesota and my family and I were curious how much ice would be on top of our pool. So I unhooked a few of the safety cover straps to get a...

    CYA disappears

    My CYA gradually disappears. My location in central Minnesota. Pool temp is kept between 83F and 87F. Whenever we are not in the pool, the safety cover is on, so the pool gets relatively no sunlight. To counter act the CYA disappearance, I periodically add dichlor or trichlor instead of...

    Low (no) CH

    Here are the readings from my vinyl lined inground pool using the TF-100 test kit: FC 13 CC 1 TC 14 pH 7.7 T/A 210 CH 0 CYA 55 Temp 64 CH is 0. It was 0 last week as well. How is this even possible? Should I be concerned? If I have to add something, what would I add? If I check my city...

    Cloudy pool - high CYA

    I am having problems opening my pool (had problems last year as well). 17K gal pool. Last year when opening the pool was green and I needed a whopping 70 lbs dichlor before the FC would stay at 10 for any length of time. Needless to say, it took forever because I wasn't adding enough dichlor...

    New heater size

    My old 175K BTU natural gas heater (30 years old) is due for replacement. The gas regulator/valve is flaky and can't hold a constant burner flame anymore. Amazing that the heat exchanger has made it this long with all the abuse I put it through. Although I suspect that maybe the heat...

    Heat pump or natural gas heater?

    My natural gas pool heater is 30 years old. I am surprised it has lasted this long, but it would not surprise me if it would spring a leak one day. So I am saving up my $ for a replacment heater. Location: Central Minnesota. Electric rate = $0.08720 per KWH Gas rate = $0.00908 per cu ft...

    Expected temperature rise

    I will reiterate what is in my signature. Minnesota climate. 17K gallon 18X36 inground pool. 75K BTU natural gas heater. 1 HP pump. My question is what can be expected for a temperature rise of my pool? It seems like it takes forever to heat my pool. I do not know what is normal. I did an...

    Safety cover vs solar cover heat

    For the past 10 years I have always used a safety cover year round on my 18' X 36' inground pool. My current safety cover is: Protex - heavy duty cover with 98% shade. Previously, when I bought the house, the pool had only a bubble solar cover. However after having pocket gophers, muskrats...
