I have been using pro-biotics since the start in my 180g. Currently I have a pbt, orange shoulder, and sailfin for tangs. I have a pair of percs hosting in rbta
's. I also have a potters angel, coral beauty, worlds largest pink spot goby, two chalk basslets, a canary wrasse, midas blenny, mandarin, and a blue/green chromis. Along with a pistol shrimp, 3 cleaner shrimp, a blood shrimp, a harly shrimp, and a sexy shrimp. About 15 mixed snails, fighting conch and two emerald crabs (that I think are getting hungry). The two RBTA
's are huge, I never spot feed them, they get what they get and they own an entire 250w mh.
So there is my bioload. I test nitrate weekly, well most weeks at least. I have never seen nitrates get above 6ppm (that was recently, I backed off the vodka and have fed heavily). Usually my nitrates are between .2 and 2ppm (tested on salifert or lamotte). I don't shoot for ULNS
probably gives the best sps
color but it puts you on the "knives edge" whereby small mistakes are magnified), but even if you only want LNS, mb7 and vodka can really make nutrient management easy. I wont run a tank without pro-biotics ever again, assuming I have a hard core skimmer that is appropriate for the tank. Pro-biotics works, very well, but you can get yourself into trouble if you push the envelope too hard or too fast. Take your time and implement pro-biotics carefully and you will be amazed at how easy nutrient management can be.
