Did this amazing growth and color because of the SeaChem Fuel happen to also coincide with an otherwise increase awareness to the tank like a bigger skimmer, water changes, etc.? I am only asking because most are adamant about "does nothing" to "wonder additive" and it is probably neither. Have you every stopped dosing it to see if the color and growth went back down? Was the dosing done with enough control to know that it was only the Fuel? I am just curious - thanks.
Tangent, but somewhat related - I personally think that ZeoVit gets a lot of run for being awesome, but most of the time is is the answer to an increased awareness to the whole tank and the method gets the credit for a whole lot of other things that the reefer did at the same time after they decided to "get better." The easy answer is for people to say "this is all that I did," but that is probably not the typical case.
