I have had a 30g FOWLR
going since Sept--all is going great thanks to the info & advice I have found on this site.
I actually paid attention to the temperature during my last PWC
. It went from 77.4 at the start to 72.2 when I was done. I am sure the PWC
process puts some stress on the inhabitants, but is this amount of temp change something I should try to control better? I usually mix the sw
a day or two in advance so by the time I used it, it is the room temp of the house--usually around 68 in winter. I change around 20% weekly.
