Trichlor Pucks. 3 vs 1 inch.

[Thinkly]

I prefer to treat my pool with Chrlorine pucks and am fully aware that isn't the method most choose on this forum but it works for me. Regardless, I have always been told by the pool store to use 1" tablets in the inline chlorinator instead of 3". They claim the 3" takes too long to dissolve.

I am skeptical of this claim and think maybe they just prefer selling the more expensive 1" tablets. Still I buy most of my 1" tablets from Leslies online. However I am considering going with 3" this time to try and save $.

Will it be a waste of $100 or should I stick with 1" that I know has worked in the past? My pool is only ~10000 gallons and I simply can't figure that 3" wouldn't be adequate.

I use 3" pucks in my ~15,000 gallon AG pool with no problem.

You could always buy a small bucket at Wal Mart to try them out and see if you like them before you commit to a bigger bucket.

3" pucks are just fine in most situations. Occasionally, when you are right at the limit of how much chlorine the chlorinator can add it is better to use 1" pucks because they dissolve quickly. But that is only important if you are right up against the upper limit of what the chlorinator can keep up with.

your chlorinator might have a "top feed" option that allow for higher concentration output if you find 3" dissolving too slow

Given equal amounts, 1" pucks will dissolve faster, because they present more surface area to the water. You could get the same effect by breaking up 3" pucks into smaller pieces by wrapping them in several layers of newspaper and whacking them with a hammer.
