Tom, & all... I have a question to pose for you. My wife has been on my last nerve, & maybe bordering on insane. So what I have decided to do is to try a new way of planting. My wife is about 5'2", & around 150lbs or so... (she is on a diet, but still has some chubb from our 3 kids) Now, keeping in mind her dimensions, I need your suggestions on how much substrate it would require, & what size tank it would to put her in. I think I could offset the cost of expensive pre fertilized SS & just get some cheapo small gravel to cover her up... I could also go light on fish, & plant VERY heavily to soak up the excess nitrates. Discuss!
