I have all Hayward products. I got a 3 year warranty if I kept the same brand for everything. IMO, I'll recommend you stick with one brand, but you don't really need to I guess. Hayward has been great for me. If I have an issue, there's just one company I need to call or come to this forum and ask. It makes things a bit easier. Click

Do you have a sand filter? I can't tell from your signature or maybe I missed it. Anyhow this was told to me some time back.... DE basically forms a fine layer on top of your sand to filter out tiny particles that might otherwise get through the sand. See
Adding DE to Sand Filter -- Just mix 1/4 cup of DE with water in a bucket, slurry it around and slowly add to skimmer basket. Check pressure 2-3 minutes later. Repeat until PSI goes up 1 tick. After that, check PSI every 30 minutes or so, and backwash when it goes up 20-25% above baseline (or 10 PSI depending on how you roll). DE is generally designed to pick-up the finer stuff left behind at the end of the SLAM. When your pool is green and full of algae, the DE will just clog-up things and require lot of babysitting as pressure will increase quite quickly.
When you say you want to order a bulk of testing chemicals for chlorine and Ph, do you mean a testing kit to test your pool chemistry? If so, get your test kit (TF-100 or Taylor K-2006C). We recommend the TF100 from
TFTestKits.net or the Taylor K-2006C. Also, see
Test Kits Compared. I suggest the
TF-100. A proper test kit is needed to get the accurate water chemistry results needed to follow the TFP protocols.
