Short answer - it depends

How much are you feeding, and how often? (include fish and coral foods).

Alk 300? Usually measured in meq/L (ie 4-6) or dKH (ie 8-11).

What test kits are you using?

Feeding fish small amounts daily its all cleared quickly.

Dont fee the corals at all.

Run phosguard in filter with polyfilter pad

The tests were run by a good LFS.

Depending on the type of lighting you can cut it back to 4-6 hours. Keep an eye on your corals, they'll tell you if it isn't enough.
