I think it must be the word "aquarium" that makes things expensive.
Take silicone adhesives. I full tube of a suitable material runs a few
bucks at insert your favorite box harbware store here. If you want
"aquarium sealant" though, get ready to shell out 6 bucks for half the
amount.

I read this group, but only have freshwater tanks (for now, not sure
why I mention that). It doesn't seem to matter what the cost or use is,
if it for aquaria, it is more expensive!

Hi Kurt for one thing the Evaporator in the chiller is Titanium, a very

I like to tinker, so I think I'll just start building my own as time
permits.

btw, I'm sure titanium works great, but is it necessary? High grade
stainless won't corrode for years, it's cheaper, and much easier to work
with (titanium is brittle). At least, my tack on my sailboat doesn't
corrode and it's been on the beach for 4+ years. They also use it for
knee replacements that are good for 20+ years.
