Re: [APD] CO2 and PH Control

["Bill D" <billinet at comcast_net>]

I regularly move fish between higher pH tanks (7.6 to 8.0) and lower ones
(6.5 or so).  I've never seen a problem.  The fish live long, apparently
happy lives.

But the aquariums involved are well planted.  I've never had an ammonia
problem; I've never even tested for it.

The GH in these tanks differs by up to 8 degrees GH.

Perhaps someone could conduct an experiment of the effect on fish of larger
pH changes, controlling for water hardness and ammonia/ammonium?  Then we
wouldn't have to speculate.

Bill
