Ok, sk you guys are suggesting that i, to paraphrase don's post in another forum, go jurassic on this tank's butt and raise co2 levels to the point of prehistoric times when staghorn ferns grew bigger than most people's houses....lol i can do that. In fact, i'll set it up tonight.
That's why i love this forum. Not only sound opinions/advice, but data!! I once heard an expression and i use it to this day...."in God we trust, all others must show me the data!"
Thanks again guys!!
