I am unsure if it's dirt, old DE, or algae. I am attempting to push all of it down the drain, but this also just mixes in with the water making clouds. Any advice?
Answer
First off i would use a regular pool vac and put your filter on waste and just get rid of it once and for all by slowly sucking it up (take your time as clouds happen when you go to fast). If your still using an old DE filter then personally id give it the old heave ho and get a sand filter as they are not that expensive and are much safer and easier to maintain then the DE filters especially since the dust they use to re coat them is considered a carcinogen.
If your making clouds chances are it isnt algae as it usually acts like super glue to the walls of your pool until you super chlorinate it into oblivion. Might be dirt but if it doesnt come up with the manual vacuuming i highly doubt it. If you do have a DE filter it might be junk that made it from the DE filter into the pool and thus always makes it way back in. If its a cartridge filter it could be your filter is clogged up and is thus missing material and just reshooting it out into the pool. Simply hose down a cartridge filter until clean with a pressure washer and reinstall.
Short Form Answer
1.) If you have a DE toss it and get a sand filter, much easier to maintain and safer to use
2.) If your not sure what it is in the bottom check your chlorine levels if they are non existent or low super chlorinate and see what happens to it then (whether it vacs up or not)
3.) Use a manual vac for cleanups and the auto vac for basic weekly maintenance when your not using the pool.

Over 300psi pressure in my Purex 3-cartridge pool filter blew cover off the canister.Filters were Clean. Why?

The pressure gage was pegged/stuck at 300psi. Previously under same conditions, i.e. clean filters, the pressure gage burst. This gage had a maximum of 60psi. On another occasion the 3/4" circulating lines that are about 2 feet below the pool water surface jettisoned water about 3 feet above the water surface for several seconds. Does anybody sell automatic (say 50 psi) pressure relief valves to prevent such dangerous operation? Can power disturbances-high voltage/frequency swings create such dangerous conditions? Being an electrical engineer I know that motor torque increases with increase with voltage and that motor speed increases with increase in frequency. These increases then can cause the pump to push more water through and if the water lines cannot handle the volume the result then could cause dangerous pressure to develop.
Answer
You must have some form of restriction in the outlet from the cartridge canister to cause such a pressure build up. Check that there is nothing floating around loose that could block the outlet. Are the outlet hoses flexible or rigid, sometimes the inner lining of a flexible hos can separate and block the hose. The idea that power frequency fluctuations would speed the motor up can be ruled out as if the frequency fluctuated enought to cause that to happen the Power Station Generators/transformers etc would all have tripped way before it could happen.
