Re: [APD] Re: Aquatic-Plants Digest, Vol 18, Issue 7
I think that's jsut a matter of the liquid, being denser,
not changing temp as fast. And your talking about a rapid
dump of tank. With the little bit that goes through a
regulator for aquatic plant purposes, it's not going to
cause any problems. The fellow that started this thread
jsut wanted to know if he'd be in trouble if he put his
tank off-vertical for space reasons. It's very unlikely
that he will. I've only got 5 tanks to try this with, all
at various flow rates for aquatic plant purposes and they
all do fine, even the really cheap regulators.
Has anyone gotten diff results?
