CO2 bbs

[PK1]

This is from another thread, I have moved it here so we can discuss more:

At very high light, I aqdd about 1 bubble every 3 seconds to a 20 gal.
I add about 6 bubbles(they are 3x larger) to 350gal per second.

Mist or Reactor methods.

Alright... I add 6 bbs+ to my 90 gal with 265W on it, that's the only way I get descent pearling, which happens only after 6 hours of lights on. Does this mean that I am:

1. Adding too much CO2 (no dead fish though...)
2. Something else is amiss requiring me to add "too much" CO2?

Thanks!
