Hi,
Also - What brand of Chlorine tabs are you using and are they "stabilized"
You want to make sure to buy stabilized tablets and also like Jeff says above get some stabilizer

This is not true. Just because Trichlor is 90% Available Chlorine while 6% bleach is 5.7% Available Chlorine just means that Trichlor is far more concentrated by weight, but bleach is very inexpensive per pound since it's mostly water. You also need to take into account the extra pH and TA adjustment products you need with Trichlor since it is very acidic. If you do all of that, then you find that bleach can be less expensive as shown in this post (the prices are older, but are still relative). I'm not even counting the algaecide or phosphate remover that is needed to prevent algae as the CYA level climbs. For every 10 ppm Free Chlorine (FC) added by Trichlor, it also increases Cyanuric Acid (CYA) by 6 ppm. So even with a low 1 ppm FC per day chlorine usage, the CYA increases by over 100 ppm in 6 months unless there is water dilution.
Personally, I use 12.5% chlorinating liquid from my local pool store because it is reasonably priced and they reuse the bottles which is better than recycling. My 16,000 gallon pool shown here costs me just $17 per month in chemicals with a little less than 1 ppm FC per day chlorine usage (the pool has an opaque electric safety cover and is used 1-2 hours every day, more on weekends). The pH is fairly stable and I add a small amount of acid every 1-2 months. The pool is kept warm at 88F. I don't use algaecide, phosphate removers, clarifiers, or anything else though this year I did add 50 ppm Borates to the pool though this was optional (yes, they are a mild algacide and a pH buffer). My fill water has 300-500 ppb phosphates and I've had 2000-3000 ppb phosphates in the pool, yet my pool has remained algae free because I've maintained an appropriate FC/CYA ratio based on science known since at least 1974 (see this paper).
Clorox Regular bleach is 6% sodium hypochlorite and 5.7% Available Chlorine. Most pool store chlorinating liquid is 12.5% or 10%. It's only around twice as concentrated, but usually more than twice as expensive for the same volume (note that bleach is usually sold in 3/4 gallon containers while chlorinating liquid is usually sold in gallons, so one must adjust for that in comparing the two). 6% Clorox bleach at $1.25 for 96-ounces would be equivalent to $3.65 for one gallon of 12.5% chlorinating liquid. There are over 20,000 registered members at The PoolForum and over 10,000 at Trouble Free Pool many of whom use bleach and have comparison shopped for pricing (adjusting for strength and volume appropriately). People do, of course, add Cyanuric Acid (CYA) to their pools to start with and some use a mixture of Trichlor and bleach or chlorinating liquid if they have reasonable dilution of the water. The key is having a good test kit, getting to know your pool, and understanding the basics including maintaining an appropriate FC/CYA ratio.

I don't think household chlorine would be appropriate to use for pool water I think you should change the brand of chlorine you are using
