    Unusually Low Back Pressure

    I recently took apart my DE Filter to wash it out. After I put it back together, the back pressure was 10psi, which is about what it normally is after cleaning it, so I was happy. Recently, however, the back pressure has dropped. It's currently 2 psi. I've also noticed that the water is not...

    Having a hard time maintaining chlorine & stabilizer levels

    Earlier in the year I was easily able to maintain appropriate chlorine levels by setting my SWG to about 25% and running my 2 speed pump on high about 40% of the time. Lately, and what seems to be all of a sudden, I've had to make some major adjustments and I'm still trying to find the right...

    High FC & TA

    I'm quite new to this, so please bear with me. I just received my TFT100 kit last week and here are the test results from this weekend. FC: 11.5 CC: 0 TC: 11.5 pH: 6.8 TA: 260 CH:190 CYA: 55 The first test I ran was for CYA, which originally read somewhere between 0 and 20. I added stabilizer...

    CYA Test Clarification

    I received my TFT Test kit today. Super fast service! I only just ordered it the day before yesterday! Anyway, I need some clarification on the CYA testing instructions. It says to "Fill the Red-capped CYA mixing bottle to the bottom line with the pool water. Now, fill the bottle to the top...

    Vacuuming to Waste

    When vacuuming to waste, I normally close the opposite skimmer to increase suction through the skimmer I'm using to vacuum. Should I also close the valve that shuts off the drain that's at the very bottom of the pool? I'd think that would increase suction even more, but I don't want to put too...

    Backwashing My DE Filter with a 2 Speed Pump

    I have a Whisperflo 2 two speed pump (1.5/.5 HP). I typically backwash on low speed, but I'm not sure if I can use high speed. It seems like high speed would do a much better job dislodging the sludge, but I'm afraid it could damage the grids. Can anyone tell me if it's okay to backwash my DE...

    To Cover or Not to Cover?

    I've had my pool for four years and I've never closed or covered it. The guy who installed my pool recommended I not spend the money on one. When the pool and all associated equipment is brand new, it seems like good advice because it's so easy to keep everything clean. However, as time goes on...

    Damaged DE Filter

    Hello! I've had my pool for four years now. The first couple of years was easy to maintain because of the SWC but I'm now realizing that the guy who installed it did a lousy job teaching me how to take care of it. Because it's becoming much more difficult to maintain, I've been doing a lot of...
