OK, let's see if we can clear this up:

1) It's your pool. What you do with it is your choice. You are the ultimate king, queen, or despot in your backyard. It's also your responsibility when something goes wrong.
2) We advocate a particular philosophy of pool care because it is based on logic, experience and pool chemistry.
3) Our basic advocacy of the B-B-B strategy is the mainline. It is not the only one. For new concrete pool owners with new water I frequently recommend they use Tri-Chlor tabs in floaters because the side effects of Tri-Chlor will be beneficial. But for most people B-B-B works perfectly.
4) The side effects of Tri-Chlor on your water are real, measurable and drastic. Your CYA will continually increase, and your pH will be pushed into the acid range (these are great for new concrete pools, lousy for the rest of us).
5) There are virtually NO side effects of liquid chlorine on your pool water. It doesn't alter pH noticeably, and it doesn't add CYA. This is a fact. That is why we prefer it.
6) Higher CYA requires a higher residual level of chlorine to prevent algae. Many people who have used tabs for years find themselves with CYA levels of 100 or 120ppm. At these levels you MUST maintain your chlorine at a minimun of 8ppm--much higher than most test kits go. Otherwise you will get a an algae bloom. Not may, will. Sooner or later your CYA will rise from the tablets.
7) We do not advocate Bleach because we "like" it, but because it is the simplest, cleanest and most effective way to get chlorine into your water. It's also the EASIEST by far to calculate how much it will add (1 gallon of Regular Chorine--5.25% -- will add EXACTLY 5.25ppm of FC to 10,000 gallons of water)
8) We (PoolDoc, the moderators and the most experienced members) practice what we preach in our own pools. Our own, personal experience tells us our methods work.
9) We get lazy and make mistakes as well. When that happens, we give ourselves a kick in the rump and follow our own rules--and re-inforce to ourselves that they work. I had a minor bloom last summer. Cleaned it up in 48 hours--by dosing my FC up to 15 ppm and keeping it there.
10) If you have a problem, you can follow our advice, or the pool store's. Again, it's your pool, your choice. I know LOTS of people who insist pool care is a snap, insist they never have a problem and don't follow our rules. OK. Enjoy.
