Use a blend of about 85% calcite with 15% corosex. this should put your ph level at around 7.5, if you use too much corosex, the ph could go over 8.5 which is the upper limit

Ph level is at 'ideal' chlorine level is at 3.0 but the pool water is still cloudy. Please help?


The cloudiness could be suspended particles or algae. Use an algae k i l l er as recommended, then a flocculant (water clarifier) as recommended, then vacuum the pool bottom and run the filter overnight.

After that check the ph, alkali level, chlorine level, and adjust as needed. That should do it.

Using a pH meter to care for your fish


pH values are the acidity of a body of water. Neutral water has a value of 7.0 meaning that it has equal amounts of hydrogen ions and hydroxide ions. When more hydrogen ions are added the water then the number goes down and the water becomes more acidic, or if the amount of hydroxide ions goes up then the water becomes more alkaline.

pH levels in your fish tank can prove to be fatal if they aren't monitored properly. While there is no secret formula for the perfect pH level for all fish it is best to keep all the fish from the same bodies of water together. Salt water fish shouldn't be put in a tank with freshwater fish because they need different pH levels.

Throughout the day the pH level of your fish tank will change although these slight changes shouldn't be too harmful on your fish sudden changes will prove to be fatal. When you are moving fish from one tank to another you want to make sure that the two waters have the same pH levels. When you want to buy a new fish check the pH level of your fish tank and then the pH level of the water at the pet shop to make sure that the levels are not too different.

You should be checking the pH levels of your fish tank at least once a month, but more often is always better. When you take the pH level you should write it down in a log book. You should try to take the pH level at the same time every time you take a reading because at different times of the day the levels would be different. Try to keep yourself from going crazy, if the pH level is a few decimals off of perfect your fish will be okay. If the level is fairly regular you shouldn't have to do anything unless your fish show signs of distress.

What are the most common acid neutralizers to change my waters ph level?


calcite, magnesium oxide, or gravel. if it is for drinking water, make sure the neutralizer is food grade quality

Blue water stains in shower


Blue water stains are not caused by hard or soft water. Blue water or bluish green water is caused by the PH of the water. Low PH can corrosion of plumbing (copper lines) causing bluish green water or water high in alkalinity/PH can cause the same issue. Therefore there is no adjustment on the softener to correct this. I suggest a PH test to see what it is. If the PH is 6.5 or lower a calcite filter is recommended to raise the PH.

Is there maintainence for a nuetralizer tank


For a pH of 6.0 to 6.9 a type of naturally occurring calcium carbonate media called Calcite is used to neutralize the pH. For water with a pH of less than 6.0, magnesium oxide is blended with Calcite to bring the pH to 7.0 or above. The Calcite or the blend of media is put in either an up-flow neutralizer tank or a down-flow neutralizer tank.

Acid neutralizer water systems are typically installed after the well pressure tank.

In down-flow neutralizer tanks the media flows from the top of the media inside a vertical filter tank down to the bottom of the tank, and up a distributor tube and out of the filter to the household piping. Down-flow neutralizer tanks also act as filters since sediment and other fine particles become trapped in the Calcite. This type of neutralizer is automatically or manually backwashed to keep the media clean.

In an upflow neutralizer the water flows down through the center distributor tube and enters the media bed at the bottom and flows up through the media before exiting the neutralizer and flowing out to the plumbing. Up-flow neutralizers do not get backwashed because the media is never compacted and no sediment is removed. Since the water is flowing up through the media the media is not compacted to theoretically it does not require backwashing.

There are advantages and disadvantages to both up-flow and down-flow neutralizers. The main advantage of the down-flow neutralizer is that it not only neutralizes the water, it also acts as a whole house sediment filter. Down-flow neutralizers are usually automatically backwashed, which cleans the Calcite media and prevents rust particles and other sediment from fouling or coating the media. Since additional Calcite or blended media must be added to most neutralizers once or twice a year, down-flow neutralizers are easier to backwash and put back in service than up-flow neutralizers which cannot be backwashed.

Up-flow neutralizers must use an internal top screen in to order to prevent the Calcite from entering the home plumbing system. Calcite has the appearance of white sand and can quickly damage valves and fixtures if the media enters the plumbing system. If the water contains iron, manganese or sulfides, these internal top screens can later become fouled and so are generally are not used for this reason. Instead of the internal top screen, a filter housing and cartridge filter are usually installed after the up-flow neutralizer tank to prevent any mineral from flowing into the plumbing system. AdChoices7577471742534232713
With down-flow neutralizers these upper screens or external filter housings are unnecessary since the Calcite is prevented from leaving the filter tank due to the bottom internal distributor screen. The bottom distributor does not get easily fouled due to the backwashing the down-flow neutralizer tank receives on a regular basis.

In filter tanks the media can flow around the media and create channels which allow the water to flow without properly contacting the media. This type of channeling is more of a problem with up-flow neutralizers and rarely happens with down-flow neutralizers due to the action of the backwash. For most residential applications down-flow neutralizers work better than up-flow neutralizers due to the filtration feature and the backwashing function.

A down-flow neutralizer can be backwashed on a regular basis to clean, re-classify and distribute the calcium media thoroughly. This backwashing allows the down-flow neutralizer to function properly and lower maintenance costs. The Calcite media dissolves better because it is cleaned and then compacted in the down-flow neutralizer tank.

Well water that is acidic can also sometimes be high in iron, manganese or hydrogen sulfide. If a greensand or other type of manganese media iron filter is used to treat the water for iron, the pH should be raised up to at least 6.8 to allow the iron filter media to work properly. A down-flow neutralizer is usually the best choice to put in front of an iron filter because the neutralizer acts as a pre-filter removing some oxidized iron prior to the iron filter. This lessens the load of iron that the greensand filter must treat. Iron, manganese and sulfides can coat the acid neutralizer media and render it unable to dissolve into the water and neutralize the pH.

There are some applications where up-flow Calcite neutralizers are more desirable than down-flow neutralizers. If the flow is more or less constant on a regular basis, such as when the neutralizer is used to fill a holding tank with neutralized water, the up-flow filter works fine. Since up-flow neutralizers have no automatic backwash control valve they are less expensive than down-flow neutralizers. If the water is of excellent quality with no sediment or iron and the flow rate is constant then the up-flow neutralizer costs less to use and uses no backwash water.

Water in pool seems cloudy now


If it seems clowdy now it is probably low on chlorine and unless this is corrected it will turn green in within a day or two. My suggestion is that you bring a sample of your water to a pool supply store and they will test it. If you have filled the pool recently with new water the two things you should be most concerned about are chlorine, stabilizer ph and alkalinity. Since your pool is clowdy the chlorine should be about 10 ppm and the stabilizer should be between 30 and 50 ppm. If you are short on stabilizer the chlorine will be gone very soon. If you have too much stabilizer the chlorine will say in the pool but it won't be as effective. Since the water is new the ph and alkalinity should be ok but the source of your water might be poor. Alkalinity is based on the amount of sodium bicarbonate (baking soda) in the water. If the level is right it helps keep the ph stable. Most municipalities supply water with 80 ppm of sodium bicarbonate in order to maintain their ph more easily. If the ph is too high it is base and causes the chlorine to be not as effective and it causes other problems when it is too low. Adding acid to the pool reduces the ph and adding sodium carbonate or sodium bicarbonate increases the ph. Since the water is new I would automatically shock the pool to 10 ppm of chlorine and treat with stabilizer to 30 ppm and then see how it goes. I wouldn't let anyone swim until the chlorine drops to between 2 and 4 ppm, the pool bottom is clearly visible and no dirt, etc is visible. I hope this helps.

2 problems one a reading of general fault the


How are you increasing the orp if not with chlorine?
ORP is not a direct chlorine reading and can be misread for a number of reasons, if your alkalinity, ph, cyanuric acid, or TDS levels are out of control, the ORP reading on any controller will be mute. These controllers manage ph and chlorine only (typically), but all the other chemicals and water treatment rules still need to be handles by the user.

It is also possible that your orp probe has gone bad. The most important thing to have dialed in is the pH, otherwise you will never get a correct ORP reading, as they are only accurate when in between 7.2-7.8 pH value.

Also, if you cant raise the pH above .5 no matter how much chlorine you add, you might just have old contaminated water, if the TDS and the CYA are extremely high, you will see this scenario.

Culligan-water control valve leaks


If this is a Culligan neutralizer you will need to call Culligan for replacement parts as they are proprietary. You can pick up the seals for the by-pass at Culligan and replace them yourself. Depending on the PH of the water and your water usage the calcite should be replenished on a yearly basis. So you may want to have them out to do that also.

Agriculture Application of Round-up


Very important to buffer the pH of the water at pH 5. Then add Roundup /Glyphosate 360 at a 2% for grass weeds and 3% for brush weeds. Ensure that the grass is dry when treating and no rain is expected within 6 hours. Please take care with roundup as it is poison .
