Hoppy, when you say you dose per EI method but at 1/2 the recommended amounts, do you mean 1/2 the recommended for 65 gallon tank and still dose per the daily schedule?
Perchance you could post the dose/regimen.
What do you do for WC's?
Good to know about the bulbs. I like the visual change so I will stick with the current setup.
(no good way to bypass the water softener and get a decent temperature on the replacement water. All hot water runs though a softener)
