I don't know if it's taboo or not but it seems to me that there are a lot of people on a certain other forum that extoll high light fixtures on small tanks...and then promptly have their 200 dollar fixture suspended 4-6' above their tank in order to keep their colors from completely burning up. Is there a reason to do this? Or is it just a bunch of folks with too much money to spend. I see folks running par38s on their 5g tanks...only to end up suspending them a good 2-3' up...which equates to about a 50% par reduction. I've spent a good deal of time doing high light planted tanks and from my very own experience and from the data of other hobbyists I can say for sure that PAR-distance relationships are extremely potent in terms of reductions...so is it just me or are a good number of people overspending on lights only to have them wasted suspended 3-4' above the tank? I know in the past many people grew a bunch of softies and even some sps on highly inefficient T8s....Have we taken a few steps too far and backwards? I've just started this so I might be missing something here...Please enlighten me.
