@jmanieri , Do you happen to have the bearing part numbers, or dimensions? My motor sticker is exactly the same as yours, and even looking up the motor part number (which appears to be SP3220Z1ECM, although the M48... and E32... numbers are also the same on both of ours) I can't seem to find...

It certainly doesn't have to be sequential days. You just need to remove a given volume of water, replacing it with water with no CYA, to get where you want to get. If you did it just for the 2 weekend days each week, it would just take you about 5 weeks to get there. The bigger chunks of...

@Not4You, I was in the same boat about 3 months ago, with CYA in the ~200ppm range. And as it was July in Phoenix, I was even more concerned about letting my plaster dry out. What I did was start pumping water out as soon as the sun went down and let it go until I was ready for bed. Depending...

Kienschl, If you were measuring the chlorine level every hour, you should have a pretty good feel for how much chlorine the pool has been consuming, and how much chlorine you have been adding each day. As you progress, the amount of chlorine should be less and less, but the history should give...

You ran out of reagents in 2 days?? That doesn't seem right. Which reagent did you run out of? Maybe you should review the procedure here before you get the new reagents so you don't go through the next batch so quickly.

Thank you for the confirmation, chem geek. And I would like to sincerely thank you for the work you do on this site. Not only for your obviously strong technical knowledge, but also for your willingness to share that knowledge with others. Being a chemical engineer, I don't feel like I'm done...

I'm not sure if this was directed at me, the Original Poster, or both, but I'll reply anyway. :) I would love to be able to do this test, but my water is now crystal clear, so it won't tell me anything useful. On my drive home from work yesterday I also thought about trying this test as well...

If the water is already cloudy, how reliable is the CYA test really going to be? Granted, I'm new to this TFP thing, but based on my recent experiences the CYA test was significantly affected by my algae problem. I already had an algae problem when I got my test kit, and my CYA tested over...

I just went through this process with my pool for the first time, and one thing I learned is that your CYA results may not be very accurate if you currently have a significant algae/clarity problem. The CYA test works based on the opacity (how clear) the resulting solution is. The cloudy water...

So, I finally got my CYA down in the 30-40ppm range, so I started my SLAM. (It's hard to tell what my CYA really is given how cloudy/green my water was from the algae. I'll test and adjust the CYA once my SLAM is done.) I started my SLAM four days ago, and have put in a total of 23 gallons of...

Great! Thanks for the feedback. I have read through Pool School, and I have some water chemistry background already, but I'm new to pool care. So I just wanted to make sure I was going about this in the right order, and I wasn't overlooking something I just haven't learned yet. I'll keep...

So, I got tired of fighting algae in my pool, so I did some research and found this forum. I loved the idea of using cheap generic chemicals (rather than expensive proprietary mixes of chemicals) that will allow me to adjust one single parameter at a time. I figured I couldn't do any worse...
