  1. Trichlor is the least expensive source of chlorine between the two. Trichlor has more chlorine by weight and less CYA by weight than "pure" (anhydrous) Dichlor. But the chlorine makes the Trichlor weigh more (per molecule) so the net effect is that in 10,000 gallons 1 pound of Trichlor gives 11.0 ppm FC and 6.7 ppm CYA while 1 pound of Dichlor gives 6.6 ppm FC and 6.0 ppm CYA. HOWEVER, this is for Dichlor that is DIHYDRATE. Part of the inefficiency of dichlor is that you are buying water with it (in "dry" form as it is a hydrated crystal with the Dichlor). If you were able to find ANHYDROUS Dichlor, then one pound would give 7.7 ppm FC and 7.0 ppm CYA. So with anhydrous Dichlor, you get a little more CYA per pound than with Trichlor. But anhydrous Dichlor is far less common -- most is the dihydrate form. I hope this helps.🙂
  2. Lots of helpful comments already shared here. Yes, using liquid chlorine is a safe and smart choice. Cheers,
  3. Hayward is all sourced in China, Pentair has some parts made there as well, but not all Pentair pumps imo are worth the extra money. Just personal experience. My last pentair IC40 lasted for more than 10 years.
  4. Only reason I would tell you not to get it is that it is expensive. But, if you can afford the money, time and commitment to it then by all means, get one. Soaking in a hot tub or spa after working in the yard is the best. I will take a hot tub/spa over a swimming pool any day. We had a great spa for 20 years and then have been without one for 15 years now we have one again. This time I wanted to be more organic and found using a chlorine-free oxidizer once a week does the trick and keeps it clean and clear for 6 to 9 months without having to change the water. The perfect spa/hot tub for us is fiberglass, round with a seat high bench all around the tub, jets at several different heights. This allows for seating for several friends or just the two of you to stretch out.
  5. I assume that you must be using a stabilized chlorine as your sanitizer for the spa. The stabilizer in the Chlorine is the Cyanuric Acid. Each time you add chlorine to your spa, you are also adding CYA to it as well. After so much is added it just builds up more and more, and that is why it is reading high on your strips. There is nothing you can add to lower it, other than fresh water. So in your case, I would drain and refill. But, if the water is clear and smelling good, you should still be in good shape until your next drain and refill. High CYA on pool can cause lots of problems, so I assume if too high on a spa, it can do the same as well. Here is a blurb about CYA that I copy and pasted off of the net: The second (and more significant problem) with a high stabilizer level is that it greatly reduces the effectiveness of the chlorine in the pool. Remember that stabilizer works by slowing down the reaction of the chlorine in the pool. At higher concentrations, it slows down the reaction so greatly that it significantly reduces its effectiveness. This is seen in the fact that yellow algae becomes a lot more difficult to control and the water can become dull. The unseen hazard is that it is also less effective against bacteria, etc, leading to concerns about how sanitized the water may be at any particular moment. The kill time of chlorine is normally measured in milliseconds, but at high stabilizer levels, the kill time becomes seconds and minutes, and time is critical in water sanitization. Hope this helps! 🙂
  6. Generally, pool owners advice against using bleach that is splashless, scented, or extra whiting. It should resolve itself in a day or so with the pump/filter going. But yes, stay away from those too. Just regular/plain Great Value (Wal-Mart) or Bravo (HEB) bleach. I would recommend you start scooping the foam out if you can. The thickening agents used in splashless bleaches are designed to be mixed in solution with concentrated sodium hypochlorite and high pH (from the excess lye). This means that when you add it to pool water that has a much lower concentration of chlorine in it, it will last longer than you think.
