Re: Here's my White Flag, I'm ready to surrender. (w/test #' Kathy, After reading your post, I suspect your yard is such that ground surface water is running into your pool. A search revealed that you've had issues in the past with mud running into the pool. This would mean that you're...

Re: Desperately need advice. (Day 9--We have a clear pool no Congrats! Glad to hear you got your pool cleared up. Things should be much easier (and cheaper) from now on. Just keep the chlorine level in the range for your CYA and don't over adjust the PH and things should stay nice and clear...

Re: Desperately need advice. Green pool won't clear up! Others with more experience are probably already typing a response, but my guess is that their answer will be: Get a good test kit, find out your CYA level, use liquid chlorine/bleach, and remove any solids at the bottom. If its taking...

Thanks mas985 I also re-reviewed your Hydraulics 101 link and am now less concerned about the impact of pump station height (in comparison to the pumping suction). Very Fine adjustment valve it is. Although now the wheels are spinning on how to use a linkage attached to the mechanical pump...

General question for passive chlorine feeder tinkerers: How high is your pump station compared to your pool? I would think this could make a big difference in the performance of a given setup. For example, my pump station is in my garage, about 5 feet above the pool water level. Any time I...

I've been working on a venturi aerator for raising my ph. I found that a length of tube at the return nozzle worked well when I held it in the right spot with my hand. When I tried to assemble a pvc piece to thread into the return and hold the tube in the right place, it got much more tricky...

88 degrees! Thanks to that same Chicago heatwave. Being our first season with this pool/house, I thought we would have trouble getting our pool warm with the amount of shade it gets from trees. As soon as the east end of the pool is out of the shade, the west end starts to get shaded. I...

Perhaps the pool store has something to sell us that will cloudy up our water and make those leafs at the bottom disappear. Last time I was in the pool store (buying overpriced plastic pole clips which still didn't cost enough for them to allow me to use a credit card) I had to bite my tongue...

I worked on the design for an aircraft hanger which included sail shades at the entrance. At that location, wind was a big concern so we talked to some reps for sail shade products. From that research, I'd always recommend sails with four points of attachment in a hyperbolic arrangement (high...

While testing the water last week, I watched an ant carrying half a dead ant across the deck. It was headed straight toward the pool. I wondered if he'd fall in or not so I continued watching. To my surprise, he got right up to the edge and dropped the dead ant into the pool then proceeded to...

I'm in the same boat with shortbus! :wink: Got hit with a cold spell here. Pool is holding right around 72 degrees for the last 2 weeks despite highs in the 50's for many of those days. Thank you solar cover. But we still haven't gotten FC down from shock level after treating the...

The hose clamping valves mentioned by several posters gave me an idea for making a simple diy / homemade precision valve. This should cost less than a dollar in materials and take less than 10 minutes to make (if your drill is handy). Take two pieces of wood... sketching... see attached...

So I was googling for pool area alarms (any suggestions welcome) and an odd result came up. It was this video of an 8 foot alligator in a pool in Florida. Enjoy: http://www.youtube.com/watch?v=oiIKuCBjy3Q Sorry if this is old news to everyone, but I searched the forum first and saw no...

Last November we purchased a home with a pool. A couple weeks ago I took off the winter cover to find black/green water in the pool. Since then, I've been reading and following advice I've found on TFP. Lots of backwashing and vacuuming. Thanks to TFP, I've gone from knowing 0 about pools to...
