For all of you guys with large tanks...500+ gallons. Upon first startup was your water kinda yellow/brownish? If so, for how long? All of my params are right, fish are all healthy and eating like horses. I have a drip system running. The sand is new, some of the wood is new. I did wash the sand really good, and soaked most of the tannins out of the wood. Was just curious how long it might take to be crystal clear. I'm not running UV, do you think maybe the white background is playing a part on showing through? Running 2 100 micron socks, I have 50's on the way. I have 2 shop lights with 8000k bulbs, thinking of switching to a 6' 10,000k led light. I think that color temp with 8400 lumen should light the tank a little better? Any opinions? Tank has been up and running for about a month, I do have some diatoms still but they seem to be dispersing slowly.
