FWIW I've never used seachem excel but from what I've read it's only really
useful in smaller sized tanks as it becomes too expensive in bigger (50G)
heavily planted tanks with high lighting.

It sounds like mixing 2 liter bottles is a bit of a pain and a potential
mess.

With the price and size of the CO2 rigs I'm going to have to think about
it.
It becomes a question of upgrading my wood lathe or putting CO2 into
my largest aquarium.

How often do people using Excel add it to their tanks. Is there a cheeper
solution like Excel? The instructions say to use it as much as once a
day.

ones to think about installing for a 65 gallon tank. What is this
DIY
CO2 system everyone talks about?

DIY CO2 involves 2 litre bottles, yeast, sugar and water. For a tank
of
your
size, it can be done, but you'd need a series of 3 or 4 bottles, maybe
more.



4 bottles on my 77g work fine however it gets to be a pain always mixing
up
new batch . I have just purchased a CO2 system with Clippard value but
need
to find a coupler to join the fitting the Clippard goes into to my
regulator which has different threads. Anyway should be up and running
on
Monday so no more mixing and PH swings.
