No problem Bob.
I probably would just have wasted the cash on something stupid anyhow. (Like a stupid speeding ticket.) If there's no benefit, I still have the ac 500 to use on a qt or hospital tank I guess. (Or I can put it under the crawlspace with the many boxes of freshwater stuff.
)
I appreciate all the advice that I've gotten here (It's not like I'm paying for it) and realize that allot of things in this hobby are based on opinion and experience.
Thanks again.
