What I should say is thanks but it seems like I've left some details out of the description. They're not dry wall screws they're heavy duty wood screws that I bought seperately. There are Eight screws experiencing most of the load, I went to this website
and calculated the weight of my tank at 1/3 volume which = 254.42 lbs / 8 screws = 31.8 lbs per screw, but they are not experiencing ALL the load because there is a second set of brackets that is accepting a smaller amount of force, even so 31.8 lbs is not enough in my mind to worry about. My research tells me that even at 70 lbs the wood is more likely to break than the screw is to rip out. My room mate and I have already tested our weight on it but I'll post a pic to provide some solid evidence
