Have a pentair ccp320 filter.brand new last year.pool water has been cloudy for two weeks.water is balancedexcept akalinity is high at 200.suspect filter problems.water was clear for a month.cleaned filters twice in two weeks.run pump 24 hrs.i clean filters with a low pressure nozzle(POWERWASHER)i inspected filters--still look new.noticed no leaks around filter.

Take a sample to a pool shop and find out. If the pool has been green you may have dead algae floating around, a sand filter will never take that out. You need to flock it or new water. Then there is the toy you call a sand filter, OK when everything is perfect but small filters and pumps just won't handle a very dirty pool.

if you remember back i'll bet you had a little difficulty getting the old filter off the suport rod, but now the new one is on, but there now is a hairline crack in suport post , this is sucking in air making pump loose prime , have a reputable pool company cut you a new suport pipe , you may find it easier for them to install it too as they dont come out too easy

too many chemicals will cloud contact the company website or did you maybe its the water change the water

Cloudy water is the bane of sand filters!. I suggest letting filter run day and night. Do not backwash until the pressure rises 8 - 10 pounds above clean starting pressure. Do not try to vacuum or stir up the sediment. when water clears, vacuum to waste. Keep the hose running while vacuuming. A dirty filter is a better filter (up to a point). At a higher pressure the filter will trap more of the fine particles that are clouding your water.

COULD BE TOO MUCH CHLORINE.

Otherwise chemistry fine?
whenever someone is vague about chemistry residual readings, but provide a pH reading, I'm always Leary.

• bring pH up to 7.6
• Balance Total Alkalinity at 120 ppm
• Bring Hardness to at least 200 ppm
• Keep Chlorine level at least 3.0 All the time
• ISO Cyaniric acid / stabilizer at least 30, not exceeding 80 ppm
• Use a Natural Clarifier weekly - rate = 1 ozs per 5000 gallons
• Use Algaecide (not from Kmart!) weekly
• Clean filter whenever pressure approaches 8# over starting
• Filter for at least 1 turnover per day. This is usually 8 hours in most regions

Follow this, should be good

NO, THIS TANK IS UNDER PRESSURE, AND EVEN IF YOU CAOULD DO A FIBERGLAS REPAIR IT IS NOT RECOMMENDED.
THESE TANKS CAN EXPLODE WHEN LEAKS ARE PRESENT!

The dirt you are getting is most likely from the air, dirt and dust present in rainwater and the small amounts present on human bodies. It is settling out and going to the bottom. I recomend a vacuum attachment that connects to your pump/filter to keep this cleaned out. Basically it "plugs In" to the outlet on the pool and will get all that out for you.

backwash the filter from main drain until sight glass is clear-this will reduce filter pressure. After backwashing return gate valve to filter position, then filter from main drain only. check water chemistry. add a clarifier to water
