this has been discussed in other threads.....
but it has been a trend to run really sterile/low nutrient tanks as of late. (wet skimming, super flow to take out particles, GFO, then the whole BB movement) Seems that this has been focused on so specifically that the fact that corals need some nutrients in the water has been overlooked. (many have mentioned it, it just doesnt stand out as much as the info on how to run a low nutrient tank)
I am no phD, not an author, not marine biologist (and i dont play one on the internet)... but it seems that in all of this fancy equipment and water stripping methodology that we've forgotten that corals need some poop and other nutrients in the water. Tough part is finding that fine line b/w having enough food in the water for corals and having too much food in the water that fuels algae, masked colors, and impeded growth.
Everybody's tank is gonna be different. How much you should feed or how much poop you should leave in the water is gonna depend upon coral load, fish load, equipment, and general tank husbandry.
Nope.... .sorry.. no silver bullet here.... just consider.....
... if you dont like the looks of your coral....
-has it been in your tank a fair enough time, under constant conditions for you to make a fair assessment?
-if it is brown... stays brown... wont grow... but all other parameters suit its needs... then too many nutrients.
-if it is light, colors arent well saturated, and you know it can look better (you got a frag from a buddy and his looks awesome)... then the coral is probably starving.
-if you've reduced nutrients and the coral doesnt look good and you've increased nutritents and the coral doesnt look good... you may just have to accept the fact that you have a naturally dull or a naturally light colored coral
think about the all-magical zeo method.... you strip the water to near sterility, then you constantly add a food source back into the tank.
i think acro keepers are always gonna be chasing colors... its what makes stony keeping challenging.
You guys asked... these are just my opinions... take them as you will.
