In 2014, I purchased a home and completed construction of a pool, pond, and spa. The pool and spa are SWG, the pond was set up to sanitize using a bromine tablet feeder. After two years of operation and dealing with algae, I have concluded I need to make a change with the pond. The SWG pool and spa are near maintenance free and are exposed to about the same conditions. As I see it, I have three alternatives that all involve dumping the existing bromine tablet treated water:
- Convert to SWG like the other two systems
- Convert to trichlor tablet using existing feeder
- Use liquid chlorine and table feeder when on vacation
Obviously, alternative 1 requires the highest up front investment, but vs. my existing bromine costs will pay back in about 1.5 years. My questions:
- Am I correct in assuming that conversion to chlorine will make maintenance easier since chlorine is a better sanitizer?
- How can I estimate the annual on going costs of alternatives 2 and 3?
- How much work is required for alternative 2 and 3 vs. 1?
- Are there other alternatives I should consider?
Some additional background:
- My details are in my signature. I am in Ann Arbor, MI.
- The pond and spa are pebble, the pond is quartzite.
- The pond is essentially a pool, the owner's original intent was to make it a very large koi pond. We were not sure we wanted that, so set it up essentially as an unheated pool. We still refer to it as the pond.
- I have been pretty careful in keeping my chemicals in balance, I do not believe my pond algae and maintenance issue are operator error.
- The pool and pond are adjacent. The pond does have a waterfall and a river that makes it somewhat more exposed to trees and pollen, but only marginally so.
- I am pretty busy maintaining three separate systems and chemical balances, ease of operation has attracted me to alternative 1.
Appreciate any and all help and advice.
