Thank you for sending the email out and posting this thread. Happy Birthday TFP, admins, mods, supporters, calc devs, everyone that wrote something that got sticky'd, everyone who did something we didn't have data on and shared the results, everyone who posted tutorials/pics/vids of methods, everyone who posted full test results with your question, everyone who filled in a signature, and lastly, everyone who took the leap of faith and followed the advice on TFP and reduced their pool care time and expenses! Awesome community and so glad to be a part of it.
Friendly reminder that if you haven't donated to TFP yet, please consider becoming a supporter when you can! Each dollar goes a lot further than you might imagine in a non-profit. They will not look at a $5 donation and complain, they will be thankful!
