Hi just trying to get things good before I take my first dive in. Water is already 68F here in the Northeast! Was checking the chemicals, looking at recommended levels and found a pretty big difference between the levels recommended by Trouble Free (TF) and those from my Pentair Intellichlor...

Summer is coming and I had my regular service come and open the pool and dump in all the chemicals they normally do. Still, after more than a week the FC= 10, pH= 6.7, TA= 40, and the CYA= 55. I'm concerned the chlorine is taking too long to come down. Should I add anything or just wait it out...

I have a 6' x 8' in-ground gunite spa with bluestone around. My spa cover is about 9 years old and waterlogged, ripped, rusting ,etc. and weighs about 150 lbs! It has 2 hinge points (3 sections) 2 sections are permanently connected and the other section has velcro. I need to replace it but can't...

I've had this Chlorinator for about 10 years and it has worked well, but this season I noticed it has been producing no chlorine. I cleaned it with muriatic acid, I ran the diagnostic that showed it was 60% used up. All the lights are green- good salt level, good flow, good cell. I understand...

Hi have a 6' x 8' in-ground gunite spa that is flush with the pool and spills into it. My original cover (7' x 9') had 2 folds with hard foam in the middle, vinyl cover. It's about 8 years old and has gotten so heavy I can barely manage it- want something new. I took out the foam and see they...

Hi all! I know I'm not the first one to have a broken down Mastertemp 400 with an SFS error LED on, but the earlier post didn't solve my particular problem. My propane heater has been working very well for the past few years. Installed in 2013, my first few years had mouse problems but I finally...

Hi I have a 900 gallon in-ground gunite spa attached to my pool. The pool is closed for the winter but the spa is open and I have used it several times this winter. This is a saltwater pool/spa with a pentair salt cell generator that works during the summer. The salt level in the spa has been...

How do I know if my Intellichlor ic40 is really producing chlorine as it should? The unit is about 4 years old, my salt level is good, all the lights are green, I'm running it at 100 percent output, I have even cleaned it with acid and there is almost no buildup inside. So why is the chlorine...

Hi the light went out in my spa and I would like to change the bulb (see attached image). I've never done this before but it looks like 3 screws hold it in. I plan to take out the screws and pull out the light and think it should be obvious what to do next. Is there anything I need to know...

Hi All, I know there are a million posts about mice in the heater and I read a bunch, but I wasn't able to find the exact info I need. Maybe you can help? Thought I would open the pool really early this year so last Monday 4/10 I scheduled the opening- the man/company that built the pool in...
