Does the chlorine test have you match colors of pink to determine the reading with 5ppm being the highest value on the scale? If so, that is the Taylor K2005. It is not quite the same as the K2006 (which can test much higher chlorine levels) but if you order the K1515 I mentioned above, you will have the missing test that you will need. It is an add-on kit so not as expensive.

I'm pretty sure your sand filter doesn't use 3-5 lbs. At least I hope not! Most sand filter have between 100-350 lbs of sand. Is there a model number or something so we could look it up? The reason I am so interested in this is because unfortunately, I'm afraid you have a poorly matched filter and pump. You have a mighty big pump for a 24ft AG pool. In the case of pool pumps, bigger is NOT better. What happens is that when a big pump is paired with a small filter, instead of filtering well, the power of the pump simply forces debris through the sand bed and back into the pool. We see this all the time here on the forum. People think they are getting a good thing when they get a big pump but in reality, it is a problem. (Just to give you a comparison -- I have a 27ft AG pool and have a 1/2 hp pump paired with a 300lb sand filter.) It is much better to have a smaller pump paired with a large filter than the other way around.

This mismatch makes it that much harder to clean up a pool so we'll have to keep our fingers crossed that your combo will get the job done.

If you can't attach a pic, another option (though slower) is to email them to poolforum@gmail.com and include your thread # (24371) in the email so the pictures can get posted in the correct thread.

I have let Ben know that I would like for him to pop in on your thread, so hopefully he'll get to it before too long.
