I added a copper-based algecide to our pool. Then 12 hours later, I shocked to pool. Our pool water turned a chocolate brown. What happended was the algecide was copper-based, and the copper reacted with the chlorine in the shock... and turned brown. We had to wait for the chlorine level to significantly drop, then add metal remover. Let the water circulate until clear. Then re-shock to get the chlorine levels up. If you wait to shock the pool too long, your water will then turn blue (ours did!).
Best course prior to adding chlorine or a shock agent is to filter the pool water overnight then add your chemicals AFTER each refill or top off. It would give you an added boost if after each top off of the pool water - you add a sequestering agent specifically addressed to iron in the fill water. Be sure to follow all the instruction on the product you are adding to the pool.
If it is turning green then the it usually means algae is present. An algacide will need to be used. Wait until the chlorine has gone down . If not it will just eat the algacide. Green can also appear when heavy chlorine levels are present. The sun's rays will eventually dissipate the chlorine. Also check that the PH is in the right level. This can also cause wierd colors. Add pH increaser or decreaser to get it in the 7.5 range. Also stir the bottom of the pool every once in a while so that the shock disperses throughout the pool. Pools just take patience. Whatever you do wrong can be corrected. Man. I am glad I don't have a pool anymore. (too much work) Hope this helps.
First- make sure your wearing gloves.
Brown water could come from- fresh fill water form a well which has tannins or iron in it. It could be algae or it could turn brown if your PH is so low (under 5) that it is burning the carbonates out of the water. This could make it look like coffee). Low PH could also be oxidizing metals in the water.
Clean out your skimmer baskets and your pump basket. Double shock the pool and add algecide. Backwash the filter for 5 to 7 minutes and rinse for 1 minute. Depending on the size of your pool your water should start clearing in 4 to 8 hours.
Shocking with chlorine followed by filtration.
you should drain it using your mouth
Just the same as not putting enough chlorine in the pool. You can treat the water the same as you would have and increase the production of the salt system.
Drain and acid wash
You have to treat pool water with pool chemicals and use a pool filter to get and keep the water clear.
You do not treat pool water hardness with chemicals. If you have hard water in your area then you need to know what the allowable maximum of water hardness is before the water needs to be changed. You remove or reduce the hardness in water by draining and refilling the pool. K
It's doubtful that the problem is related to the salt or the chlorine generator, assuming that the pool was a chlorine pool before the installation of the system. If it was a Biguanide pool, that might explain it but generally the reaction is grey and cloudy, not brown. If the pool was turned off for an extended period of time, it is more likely that something came out of the filter and plumbing. You can email with a better description as to pool type, how old, what you were using before the salt system, and how long the pool was down, etc. for a more complete answer. info@thepoolandspawarehouse.com
It is chlorine reacting with the metals in your pool water.
If you are not worried about the pool floating on a high water table or you have a hydrostatic valve on the bottom. I would drain it clean it and start again.
Your pool water may have turned green even after adding Fresh and Clear because of metals in your water. It is likely copper that is causing the water green. Your pool store will have products available to remove the metals and clear your water up. You might also have algae if you are not putting enough chlorine in the pool.
24/7 filtration
Chlorine is an effective agent against treating your pool against bacteria. You can buy supplies to test and treat your pool at pool shops.
Yes, only use clear clean water in your pool {;-). Seriously, why is it brown. If it is from rust, then you can purchase a clarifier at your pool store. If it is from leaf decomposition, then Chlorine will eventualy take care of it. If it is from pee, it is your call.
