Why does everyone use 2 liter bottles? Wouldn't you get a longer running system using 1 gallon bottles?
Would using 2 one gallon bottles on opposite sides of the tank work on a 75 gallon planted tank?
I plan on using excel and probably will till it runs out. How long do you think a 2 liter bottle of excel will last? If 2 gallons of DIY CO2
will work I'll switch over to that. Pressurized has to wait until next yr.
Its a 75 gallon medium (right now) planted tank, 1.75 wpg
dosing dry ferts 1x a week and flourish 2xs a week.
My PH is 6.8 KH
is 3 and GH
are before dosing I'll check to see what they are now and edit the post.
is still 3
I have CaCO3 that was sent to me accidentally, could I use this in place of crushed coral or baking soda to raise the KH
? I know the KH
is okay for injection but I'd rather have a bit more buffer so if anything goes wrong I have a little time to react.
