When posting a question, we will need as much relevant information about your system as possible, in order to provide you with the best answer we can. The more detail the better. That said, please try to include the following information within your post...

1. System age and size (volume including sump).

2. System type (Jaubert, Berlin, modified berlin, etc.).

3. Water flow (amount and type).

4. Filtration type (algae scrubber, skimmer, bio-wheel, etc.).

5. Lighting photoperiod, scheme, color temp, type and wattage (NO flourescents, VHO or HO, Power compacts, halides).

6. Water parameters (temperature, calcium, alkalinity, salinity, ammonia, nitrites/trates, magnesium, etc.) (the more the better).

7. Tank inhabitants (types of coral, fish, inverts, etc.).

8. Type of water used for top-off/water changes (straight tap, TWP, RO, RO/DI, etc.).

9. Additives used (kalkwasser, B-Ionic, calcium reactor [include media type], etc.).

10. Feeding (schedule and type).

Also, check the SPS FAQ linked in my tag. It may have the answer you're looking for, or at least guide you in the right direction.

Any suggestions for improvements on this list can be pm'd or emailed to me.
