I usually tell my customers to watch the pool, keep the chemicals balanced, and if it stays clear, then the chlorine is not being blocked out by the stabilizer. If it turns green and the chlorine level is normal, then the chlorine is being blocked out, and the pool needs a couple of feet of water drained off. Whatevever you do, don't use any more chlorine tablets until the stabilizer is back to normal, only use liquid or granular chlorine. The tablets put stabilizer into the water and should not be used during the winter to prevent the stabiler level from becoming too high.
Yes you must drain part of your pool when the cyanuric acid exceeds 100 ppm. Almost every health department in the nation abides by this. However, this is depated in the pool industry, even amongst my own employees. It is thought that the cyanuric acid molecule locks up the chlorine molecule when you exceed 100 ppm. Thus, you have a greater chance of the pool clouding, bacteria/virus build up etc.
To get your Cyanuric Acid (CYA) level down to the recommended ideal of 40 ppm from your 100 ppm, you would have to drain 60% of your pool water and refill with tap water (which has no CYA). Be careful about draining your pool since doing so in areas with a high water table can damge your pool. Instead, you can do "continuous" draining where you simultaneously drain (with a pump or spillover) and fill your pool (filling from one end and draining from the other, all with the pump running for decent mixing). This will take longer and use more water, however (about 150% of your pool volume).
One thing that most pool companies won't tell you is how much CYA you add to your pool by using Tri-Chlor tablets or Di-Chlor granules. One 3" tablet of Tri-Chlor provides around 2.5 ppm of chlorine, but also 2 ppm of CYA. The same amount of chlorine is provided by around 13 oz. (weight) of Di-Chlor, but this adds 3 ppm of CYA or 1.5 times as much as with Tri-Chlor. With chlorine demand of around 0.5 per day, you can easily see how you can build up an excess of CYA (about 12 ppm per month) over just one summer!
If you use a DE filter that requires regular backwashing or if you have a lot of splash out, then you will always be diluting your CYA and might prevent too much build up, but if you use a cartridge (fiber) filter and don't backwash, then you will build up too much CYA.
I had this same problem and am using winter rains to help dilute my pool and have switched to using liquid chlorine. This sure is a good argument for using a salt pool or liquid chlorine instead of Tri-Chlor!
Muriatic acid is a very dangerous type of acid. You need to wear gloves and protective eye goggles when using it. No, you cannot use muriatic acid without diluting it to unclog a PVC drain pipe.
It wouldn't "hurt" the equipment, but you would need to drain the pool to get it out. That is TOO much CYA
you need to know the PITCH of the drain line to give an proper answer
It depends on your water chemistry, if you need to drain an in-ground pool every few years to recycle the water. If your cyanuric acid level is out of control you should. If you keep it balanced there should be no need to drain it and refill. Take your water to a pool professional to see where your chemistry is at.
depends on how much benzoic acid you use. if you have 0.5g of benzoic acid , you need 30ml of water as a solvent.
A dishwasher drain pipe actually goes up to just under top of cabinet, then down slightly to join sink drain in next cabinet.
You'll need to know two things: what is the concentration of butyric acid you are starting with and how much 1 M butyric acid you want to end up with. From this, you can calculate how much water you need to add to a given volume of concentrated butyric acid to make 1 M butyric acid.
Sprinkle enough to cover the acid.
If the oil is significantly above "max" on the dipstick then you need to drain some off via the sump drain.
You should be taking a Prenatal vitamin which contains Folic Acid. You may need to take a Folic Acid supplement if your doctor prescribes it. You will need to check with him first...

Someone may need a drain camera if they have lost something of value down a drain, for example a ring. Another reason a drain camera may be required if there is a plug in the drain sewer that one cannot break, and it will allow them to see where the problem is in the drain.
It depends on how much of the acid there is. It would take one mole of, though, for each mole of a monoprotic acid.
Normal pregnant women need 400 to 800 mcg of folic acid a day. You should talk to your Dr to see if you need to adjust.
Gibberellic acid, but you do not need very much because too much Gibberellic acid will prevent germination.
it is still acid but weaker because the water-acid base ratio grows depending on how much water or acid base there is You need water to make acid (e.g. Hydrogen Chloride itself is not acid, it is an acid base, but when dissolved in water it is a very strong acid)
6 quarts of oil when you drain and replace the filter.
Any alkali. Toothpaste, NaOH, often found in drain unblockers, baking powder you'll need plenty of baking powder or toothpaste but if you use too much it won't matter as they aren't strong enough to harm you whereas NaOH will if too much is used.
Just cover the acid with baking soda and let it sit overnight.
NO You would need an awful lot of acid to do any harm there.
no drain plugs. need to drop the fuel tank below the vechice. no drain plugs. need to drop the fuel tank below the vechice.
You drain coolant from the radiator. but according to the book ther are two plugs on the engine block that need to drain the coolant from.
Any amount of acid will lower pH. However, to lower it significantly or by a given amount we need to know the type of acid being used, the initial pH of the solution, and what buffers, if any, are present and in what concentration.
