Holokai,
Don't let it be frustrating. Use the MHs when you get your next reef tank. No need to get rid of them!
Corvus is right, though, about the
CO2. Bite the bullet like we all did
and get the pressurized
CO2 system. Its potential for delivering
CO2 to the system is hundreds of times higher than with
DIY. DIYs usually deliver about 1 bubble every 5-20 seconds (or so), while a
DIY can deliver dozens of bubbles per second (though this would mean you would run out of
CO2 pretty fast). With
CO2 it can get more expensive--a solenoid is almost certainly a necessity, as it turns on and off the
CO2 in the morning and night for when you're out. A pH regulator (~$90-$110 shipped) is a second possibility, as it maintains a stable pH for the fish, and controls the solenoid. I've gotten on fine w/o the pH regulator, but I highly recommend the solenoid.
