I have to take issue with any product that is used to lower the PH. From my
experience, it has never been good to lower the ph by dosing CO2. 1 because
if either the power runs out or if yourun out of Carbon as in this product
you will have massive stress on your fish. Running CO2 without discretion
can easily lower the PH my more than a full point.
When I was testing out my CO2 system, turning it on high lowered the PH of
my hard Santa Barbara tap water from 8.1 to 6.2 Obviously, I ran it a much
lower level and the PH was much closer to 8. Also, it doesn't reduce the
hardness of the water. The reason is that the deposits are from the water
that has been electrolosized (this is probably not a real word but it fits
In essence, it's like removing the carbonates out of water that evaporated.
It only will keep the carbonates at a steady level.
Also just my personal view is that I wouln't want to expose my fish near
electrolosis or at least run some kind of grounding probe like on Reef and
Salt water tanks.
Just my thoughts,
