    Best way to lower Iron in a pool

    After enjoying several seasons of trouble free pool using the methods on this forum, I'm having a problem with Iron that I can't seem to overcome. My iron test strips show that there is no iron in the municipal water or in the pool water, but that is clearly not true. Last season I started...

    Draining and refilling vinyl liner pool at startup

    I have a vinyl liner pool, the liner is about 11 years old, but has given me no trouble and perhaps it can hold up a few more seasons. However last year I had a bit of a headache with Iron. I'd like like to replace some of the water to reduce the iron, and I think it would be smart to do so...

    Sour water taste, why?

    Problem: Pool water continues to taste sour despite water apparently conforming to TFP specifications. Background: I opened the pool this year in may with a slam, and balanced the chemistry as normal, but on the first swim my kids stated the water tasted sour. Everything tested in the...

    Heat Pump Plumbing

    Just opened the pool today! So I have the heat pump plumbed as the last stop before the salt generator, and then it goes into the jets. There is a manual bypass for the heat pump loop that I can use during slams and for other reasons. However I noticed something. I have a variflo multiport valve...

    pH Keeps Rising out of range but why?

    TA 80 FC 8 CC not tested CYA 30 CH not tested PH 8 Water condition - very clear SALT - 3000ppm I have a vinyl liner salt water pool. I noticed towards the end of summer, my pH keeps rising to around 8. I usually address this once a week by adding MA(yes I finally got comfortable using this...

    How to Fill pool faster

    In the summer when I'm not around, I sometimes have someone stop by to backwash my filter, empty the skimmers, and check my chemicals etc. However a problem we've been having is that the water level is too low to backwash, and it can take an hour or more to top it up. The pool has no main drain...

    Pool volume for Autopilot

    I replaced my autopilot whose screen failed. I'd like to input the pool volume into my autopilot for the salt adjustment calculation, only I don't know how many gallons the pool is. It seemed accurate before, but without the screen I could not determine what volume the autopilot was using. The...

    Troubleshoot aquacal SQ150VS heat pump low pressure fault?

    I tried to fire up my aquacal SQ150VS heat pump for the first time this season today and after starting up for a couple minutes, it shut down and gave this error. Now when I cut the power and turn it back on it just displays the code without trying to start up. Is there anything I can try before...

    Display Blank on Autopilot but Still Working

    The display is blank today on my Autopilot digital, but it appears to be otherwise working. My forum search suggests I should check the wiring harness(done, I reseated the connectors, no improvement) and then replace part 833N, the upper circuit board. The part seems to run about 300 bucks. Is...

    Aquacal Poolsync

    I use an aquacal pool sync to control my aquacal heat pump. I don't often heat the pool, so it's useful to turn it on remotely to give it more lead time to heat up the water. However I've noticed that every two weeks or so, it loses the wifi connection, and is unable to reconnect on it's own...

    Do I need to worry about sulfates?

    I've been using dry acid when I need to lower my pH, which is not often. I really don't want to keep muriatic acid around or use it if I can avoid it. I've used it for other purposes, and it's not really nice stuff. I don't want to have an accident with it and would prefer the safer alternative...

    CYA test says zero, but should I add more?

    So I noticed my saltwater pool is struggling to keep up chlorine. There was a big storm here over the weekend, and chlorine read zero when I went to service the pool today. I ran the CYA test from my tf test kit, the reading was also zero, water clear all the way to the top. Maybe a little haze...

    Autopilot Digital Random Salt Cravings

    Every now and then my autopilot digital starts blinking that darn red light and demanding 40, or 80 or 107 lbs of salt, but when I test the water with a taylor kit I bought to help with this situation, the salt ppm is good. I don't really want to pay for and dump hundreds of excess lbs of salt...

    Pentair VS Watts Mystery Not Equal to Volts x Amps Why?

    I have a pentair intelliflo pump running at 1900 rpm. The pump is wired at 240v on a double pole breaker. I have a current meter in the panel on one leg of the pump circuit. The current meter displays 2.63 Amps. So in theory 2.63*240 = 631 watts. However the watts measurement on the pump itself...

    Can heater call for circulation pump?

    I have an aquacal super quiet variable speed heat pump and a pentair intelliflo pool pump. The intelliflo is normally schedule off at night, but if the heat pump is trying to raise the temperature, it wouldn't be able to run unless it can call the pool pump. The heater is not often used, so I...

    Do I need a pump on an Auto Cover in summer?

    I have a pool at a house that is often rented to vacationers during summer. I used the TFP method this summer to open and operate it, and it's worked great, and saved me a ton of money as pool service is expensive in my area, so thank you all for providing this information! I'm considering...

    Autopilot DIG-220 Repair Success with TFP Help

    I wanted to post my experience repairing my DIG-220 using info in posts from this forum, since the posts I read were so helpful and perhaps the additional information can be of use to future troubleshooters. I have a pool that I'm told was redone in 2013 by the previous owner. I have an...
