how often do you test your important perameters: salinity, ph, alk, calc? and what are they? if you have a sump, adding filter socks to the sump, a protein skimmer, or going macro algae will all help out. also how often and how much water do you change? as for the best bulb, try and get the brand that matches your ballast if you can. if not you can look for bulb recommendations for your ballast. its really hard to say. the same bulb will burn different depending on your ballast. sometime you just have to try if you cant find any recommendations and you have a non standard type ballast. they will always be around the color temperature they are supposed to, if your not sure go a little high to be safe i.e. 15k instead of 14k. and yes, if you can t5 actinics will look better then pc's but is not needed.
