Pool Green Since Opening From June First Week
by: Pranathi

We tried lot of chemicals to make the pool blue and then changed the sand in the filter, removed the top 6" of water to get rid of nitrates and refilled. Added shocks, algaecide, clarifiers, first aid based on the chemical balances that were checked every day at pool store.

Last wednesday all the chemicals were in correct range but still the pool was green. Saturday evening the readings were below chlorine - 0.5 PH - 7.8 TA - 88 Calcium Hardness - 200 CYA - Cyanuric Acid - 60 Phosphate - very low We bough 1 quart of super floc, added to pool on sunday at 9:30am ran the filter for 2 hours in circulation mode and shut off.

Backwash yesterday evening. It has been 34hrs till now and the pool has been worse dark green. We have 14hrs to check the condition until it is 48hrs. I am very frustrated and appreciate your advice.

Thanks for the question Pranathi

First thing you need to do is stop using clarifiers, super floc, First Aid, etc... First Aid, and I assume that's Natural Chemistry, is enzymes and a clarifier/flocc. Basically what you're doing is doubling or tripling up on the clarifier when you use FA plus another clarifier. You're wasting alot of money on chemicals that are not doing anything to clear up the pool. You need to kill the algae and the only way to do that is to keep blasting it with chlorine.

You're readings are alright. Just some simple adjustments and you should be there. First thing is to get your pH down to 7.0 - 7.2. Chlorine works better at a lower pH level. Use 20 oz. of acid per 10k gallons to reduce the pH 0.2. Broadcast around the perimeter of the pool, sweep, and FILTER. Be sure the filter is cleaned out and backwashed. Wear long sleeve shirt, pants, and safety goggles.

2 hours later shock the pool with liquid chlorine. It's 1 gallon of chlorine per 10k gallons. Shocking is a process, not an event. The trick is to get AND keep the chlorine above 10 - 12ppm for a period of time.

Only at this stage should you even consider a clarifier. This will help with the filter catching the particles.

You should spend no more than $50 on clearing up a pool. I doubt your pool was as bad as this one.

If you feel your situation is more complex than this, I do phone consultations for a donation of your choice. It makes things go much faster and many people have found it extremely beneficial, saving them time and money in the long run. All your questions will be answered. I have nothing to sell you so you know I'm not bias.

Pool Consultation

Hope this helps and have a great Summer.
