A layer of white residue on the bottom of a pool could be the result of many things. Calcium deposits may be the most likely cause.
If you are referring to dust from wind blown dirt etc, neither type of chlorine has any effect on the amount of dust settling on the bottom of the pool. If you are referring to white chalky dust, that comes from calcium hypochlorite. Cal Hypo is 65% chlorine and the other stuff generally does not dissolve. You should dissolve the Cal hypo in a bucket of water and poor the liquid into the pool and toss the remaining white stuff.
Yes, it is bad to let the shock sit on the bottom of a painted pool. As it ionizes, it will eat away at the paint. Since the Calcium Hypochlorite has a low solubility, I recommend to my customers that they first dissolve it in a bucket of hot water, then pour it into the pool. That should solve your problem. I ageree with previous answer. If using 'calium hypochlorite', dissolve in bucket of water, as best you can, but you will have a residue. Throw the liquid into the pool and toss the residue away (calcium, not needed in your pool).
Try casting a flocculant let it settle for a couple of days and then vacuum the bottom layer of water to waste you will see the layer you want to remove on the bottom of the pool. check with your pool shop for a good brand of flocculant.
Need more info. What type of filter do you have Sand, D. E., Cartridge? Does the white residue settle on the bottom of the pool? Can it be brushed into suspension? Does it disappear or dissipate when brushed? what are the Ph and alkalinity levels? Ken Did you ever solve your problem with milky-white cludy discharge from pool? I have same issue. Not water hardness/calcium. Water chems are in normal range. I even drained and refilled the pool. Any insights appreciated Brent
A light acid wash should remove the chalk.
The chalky substance is most likely too much shock. use Tri-Sodium Phosphate(TSP)and a good brush to clean it. drain the pool first. Well, in my opinion the chalky substance is from a painted pool where the paint is oxidizing. Brushing this only makes the water more cloudy and decreases the filters ability to maintain clear water. I have also seen this in or on fiberglass surfaces and in that case each time those pools were quite old. k
At the very bottom of the pool are the bottom drains . By regulation , they must be 36" apart . Either of these drains must be able to support the total suction of the filtration system . Theis is the Virginia Grahme Baker regulation . At other places on the pool bottom you may see smaller discs . These are the returns , the outflow of the filtration system .
-white fins not moving -gills not moving - sink at the bottom of the pool - may smell
At the bottom of the pool.
Yes, the white residue on the terra cotta pavers from the chlorine spill can be neutralized. You can neutralize the residue by rinsing the affected pavers with clean water to dilute and remove the chlorine. Additionally, you could use a solution of water and baking soda to further neutralize the residue on the pavers.
For most fiberglass swimming pools, it means that the pool is at least eighteen years old and is in need of new gel coat. All things fiberglass have a finish coat of gel coat. Because swimming pools must contend with harsh chemicals, the swimming pool gel coat does not last forever. The longevity of the gel coat depends upon two factors: 1) the pool manufacturer, and 2) proper maintenance. There is a huge difference between manufacturers. Gel coat replacement ranges from 27 years at the top, to as low as 4 years, or less, at the bottom of the list. But the average for most fiberglass swimming pools is around 20 years. Nevertheless, chalking always means that the nonporous gel coat has become porous and needs to be replaced with new swimming pool gel coat as soon as possible.
There is no filter at the bottom of a pool. Perhaps you are looking at the hydrostatic valve which is there in case your pool is emptied and Will make sure that the pool wont float in ground water.
