  ABSOLUTELY NOT!!! You can only put the PPG Cal Hypo tabs into their feeder. As bizare as it may sound, you cannot substitute anything else. Do you have a liquid chlorine feeder? You can bump up that.
  
  Before you make any changes, be sure to do a thorough cost analysis on the amount of chlorine delivered and cost per pound versus using any other type of sanitizer.
  
  Good luck.

  Lose the cal feeder and go to either liquid chlorine(cal hypo) or a salt generator especially indoors. I have a commercial facility that runs on cal tabs. What a mess!! Their fill water is well water and therefore high in minerals, namely calcium to begin with.
  The calcium levels are bumped up with the sanitizing system and then when they add water-you got the idea.Trying hard to get them to change.
  With the salt system I would suggest a dedicated monitoring and feeder system to maintain pH either with muriatic acid. CO2 is a consideration if there is a chemical storage issue. With the cal hypo a complete automated is the best as it delivers and maintains chemicals automatically. There are plenty of automated systems out there. Pick one that you feel comfortable servicing and most importantly one you can parts for in a hurry especially for commercial applications.

  IF THIS IS INDOORS YOU MITE HAVE TO STAY WITH THE ACCUTAB/ FEEDERS DOES IT HAVE THE AUTO ACID FEED? IF OUT DOORS AND THERE ISN'T ALOT OF COST INTO THE EXISTING EQUITMENT.THEN CK. W/ HEATH DEP. IF A CHLORINE GEN. AND MAYBE OZONE OR ULTRA VIOLET LIGHT IS OK. THAT OVER TIME WOULD CUT COST. I CAN RELATE TOO MUCH FOR THE TABS TOO MUCH FOR DEL.

  You cannot put any other materials into the Accutab Chlorinator other than Accutab Chlorine.
  Using cal-hypo is the best way to treat a commercial pool.
  And as Eric states it does not have cyanuric acid which at levels greater than 40ppm will actually inhibit chlorines ability to sanitize.
  I believe you would be best severed to find other ways of saving money as you have the best system and sanitizer available.
  If you do not have automated chemical feed equipment you might look into it so that you only deliver the amount of sanitizer needed rather than at a constant rate.

  Duave,
  
  Using cal hypo will continually raise the calcium hardness, over time. After it reaches 400 PPM, cloudy water or scaling formation are more likely if the pH and TA rise out of the normal range or the calcium hardness continues its upward spiral. The use of liquid chlorine does not present this type of situation. ORP control will not solve the calcium rise. A salt chlorine generator would be a better way to chlorinate, if it was in the budget. Adding an ozonator would decrease the amount of cal hypo required, to maintain any given level and this will slow the rise of the calcium hardness. You'll find more on the topic, on my website: www.askalanaquestion.com

  Duave,
  Is this an indoor pool? Cal hypo tabs are used as an alternative to regular trichlor, due to new regulations that limit the cyanuric acid level in public swimming pools. Here in Florida the Health Dept has limited the spas to 40ppm and now the same levels with pools (which was 100ppm) on cya levels.
  The only alternative would be to use an ORP system that utilizes liquid chlorine and acid to maintain sanitizer and ph levels. both liquid and cal hypo have a very high ph level and the acid feeder is a must. These units installed can run up to $2500 installed and then you will have liquid cl delivered from that point. Question is, how much is the liquid per gallon and how much will you use? plus the cost of the system installed.
  Typically any change in something like this requires engineering approval from the health dept, as well as engineering drawings, add another $600.
  So with that said you might consider keeping what you have, if it works dont replace it.
