HELP!!! Cloudy blue water

[Divers3]

We just got a new harbor master 27' x 54" 2 1/2 weeks ago......we have well water so we had our pool filled by a local fire company which the water came from a nearby creek...it was brown at first but now it's cloudy blue I have tried everything....I'm stuck I currently have de in the filter as we speak it has done absolutely nothing we have a sand filter I have taken samples to the pool place and every time they tell me your water levels are perfect your pool must be sparkling ....well it's not any suggestions please!!!

Interested in putting bleach in if anyone knows about this

Dead algae can be hard to filter. The sand filters with AG pools can be especially bad for this, since they are often too small for the pumps, and the small particles get forced through the filter.

For now, do these things:

1. Get a cheap local OTO / phenol red kit (yellow / red drops)
2. Get 16 gallons of PLAIN 8.25% bleach
3. Remember (write down) these figures: 17,000 gallons; PF=7
4. Add 2 gallons of bleach this PM, and then 1 gallon every following PM, till we've worked out another plan.
5. If your pump has 2 speeds, turn it to low speed, but leave the filter on 24/7
6. If not, add more DE, and see if the DE shoots back into the pool via the returns (where the water returns to the pool)
7. Post test results (OTO), a list of ALL the chemicals you've used, and the results of the DE test.

Yeah, I think someone here might know something about this!

Welcome to the Pool Forum, by the way!

Ok I went to the pool place to have them test my water cuz I don't have patience to wait for my kit to get here......we have a hayward sand filter 2hp pump 17,250 gallons of water ag pool.....here are the results
Total chlorine 10
Free chlorine 10
Ph 7.6
Total alkalinity 100
Calcium hardness 100
Stabilizer(cyanuric acid) 0
Keep in mind I poured 3 gallons of 8.25%bleach in between sun night and last night
Phosphate levels 300-500

Did you do the DE test on your filter?

High chlorine will help clear your pool, if there is still live algae. But if it's all dead, and simply being forced through your filter by the typical above-ground 'over-sized pump / under-sized filter' combo -- chlorine won't help clear the pool. (You STILL must maintain chlorine, to avoid growing a NEW crop of algae!)

Do the DE test. (#6 above)

We just had a 27'x54" agp installed 2 1/2 weeks ago with a sand filter the pump is 2hp......our pool was filled with creek water since we live on a well....it's was brown at first now it's a cloudy blue and it's driving me nuts I have had the water tested numerous times and every time they say the water has the perfect chemistry!! I just had the water tested this past Friday and it was showing very low chlorine levels they believe something is eating up all the chlorine I put rapid shock in and added de to the skimmer basket and then woke up this morning after turning the filter off overnight and the bottom was a brownish color which we vacuumed and it stirred everything right back up I'm ready to give up I put 3 gallons of 8.25% bleach in and now you can start to see the bottom but its still cloudy..please help I'm desperate!!! ....we have a hayward sand filter 2hp pump 17,250 gallons of water ag pool.....here are the results from tf100

cya: 60
Ta: 100
FC: 19.5
Cc: .5
Tc: 20
Ph: 7.5
CH: 140
Now what??

[PoolDoc]

1. Do NOT turn the pump off till the pool is clear. (Why did you do that?)

2. What is "rapid shock"? Don't use it, till you've posted EXACT chemical name and BRAND name. Use bleach!

3. It sounds like you have a filtration problem, not an algae or chemistry problem. Post the EXACT model of your filter and pump (get the PUMP model, not the MOTOR model. Pump model number will be on the wet end of things, not on the motor.)

In most cases, a 2 HP pump is way, way too large for an AG pool sand filter. You may well simply be forcing the dirt through the filter!
