What Watermom is asking for is the ingredient on the "shock" package. Many companies package either cal-hypo or dichlor (both are just different types of chlorine) and CALL it shock, which can be confusing. "Shock" is actually something you do TO your pool--it simply means raising the chlorine level to a point where it will fight whatever is in the pool. What method of chlorine you use is up to you, whether it's cal-hypo, dichlor, bleach, liquid chlorine, etc. So...what we need is the active ingredient in the bags of stuff your husband is putting in the pool. We also need the active ingredient in the "algae gone". How much stabilizer did you put in the water, and how did you add it?

Your best bet is to stop throwing stuff at the pool hoping it will clear, and let us guide you to getting it cleared up. The pool stores are in the business to make money, we are not--our goal is to help people get their pools clear so they can enjoy them with the least amouint of cost. You've already bought and added algae gone, which is not necessary and in fact could have added something to the water that will create yet another problem for you. The pool stores will sell you all sorts of stuff that you don't need, so the result is often a pool that is still unswimmable but a much lighter wallet. We are here to help you avoid that. However, in order to help you any further, we need the readings that Watermom asked for in the above post: Free chlorine, and either Total or Combined chlorine, pH, TA (alkalinity), calcium hardness, CYA (same as stabilizer). If you take a sample to the pool store and ask for a set of tests, they'll usually perform all of them. Get a printout, and come post the numbers here. Resist the temptation to buy the whole long list of stuff they will try to sell you (foremost on the list is Calcium, which you DON'T need in a vinyl pool but 98% of pool stores will insist that you have to add it). IF you must buy something from them, make it either a pool toy or a drop-based test kit that measures the above levels. Post your numbers here and we can get you going from there.

Also, is your filter sand or cartridge?
