My guess is that the pool was under-sanitized (insufficient chlorine for example) before you started adding the fill water. The fill water is also probably under-sanitized, or at best would have very little chlorine in it (and possibly some phosphates). You should keep a good residual of free-and-available sanitizer (chlorine for example) at all times - and add more sanitizer to cater for new topup water.
Fluorine in water is colourless, The same applies for fluorine in hexane
Your pool water turned green immediately after adding pH Plus because the chemical had increased the pH level to high. You may need to adjust the alkalinity levels of the water using another pool chemical such as pH Minus of pH Alkalinity Plus.
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.
No, you do not have to change the water but you do need to wait until the CL reading is 0 before adding Baquacil or there will be a reaction and the water will turn green.
By pouring it in the water.
why does adding water to an acid make it eaiser to deal with
ice water
*shrugs* idk. if the lime stuff is clear then red but if the lime stuff is green then Santa Claus
Adding salt to water rises its boiling point but lowers the melting point
Adding one mole of salt raises the boiling point of the water more than adding one mole of sugar to the water
saltier water.
Adding a salt to water we obtain a solution (a homogeneous mixture) not a new chemical compound.
