Hi and welcome to the Pool Forum!

I just wanted to say hello and welcome you but also to caution you a bit. We have lots of 'pool guys' who come to our forum. Sometimes they are trying to sell things which is a big no-no. Others come to give chemistry and maintenance advice which is also frowned upon as a newbie. Especially since our methods are pretty different from what most of the pool industry believes.

So, please do us both a favor. Feel free to read and ask questions if you need some help with something but refrain from giving chemistry advice that differs from what we teach here on the Pool Forum. That is one thing that sometimes causes pool guys to lose their membership. Hope you understand.

I'll let someone else help you with your question about your DE filter.

Again, welcome and hope you enjoy participating with us!
