I hear ya. Hopefully soon I'll be able to get a pressurized system and take
my tank to the next level. =)

thanks.

Without CO2, my PH stays around 7.1 - 7.2 maybe a little higher as best I
can tell with my test kit. My KH before CO2 was staying around 2.

Ideally, you want CO2 to bring your pH down to 6.6 or even 6.4 with that
KH.
And you might find it difficult to keep enough CO2 in the tank once you
increase the lighting. With a 75 gallon tank and high light, DIY CO2
isn't
easy.
