Coral color: If you use zeo/vodka (with a skimmer) and have pale coral colors, it is not because the "nutrients are too low". It is because the FOOD is too low. The skimmer removes the food (almost all of it) that the corals need to eat. Turn the skimmer off and the colors will come back. Of course your nutrients (Inorganic Nitrate and Inorganic Phosphate) will come back too, but hopefully you now know how to fix that by now. Some people mistakenly try "adding nutrients" such as potasium nitrate, but that is the opposite of what is needed. Nutrients (Inorganic Nitrate and Inorganic Phosphate) are not needed; FOOD is needed. Eric Borneman says: "Adding potasium nitrate to a tank whose corals are losing color because of zeo/vodka dosing is the most convoluted, complex, unnatural and bizarre way to get to an end result that is so easily achieved other ways."
Screen Growth: Don't forget that the more algae you remove every week from your screen, the more nitrate and phosphate you are pulling out of your tank. Thus, the more growth, the lower your Inorganic Nitrate and Inorganic Phosphate will be in your tank, and, the more baby pods you will have in your water.
Bulbs: Importance of the light being consistant across the screen: CFL bulbs are cheap and easy, but they put all the light into one spot. So there is really no purpose in having a screen much larger than the bulb:
