150$ of LR
isn't really much...for my 70lbs of LR
I had to pay well over 300 dollars. It's suggested to have 1.5-2lbs of LR
per gallon of water, so I would probably add another 300$ to your LR
I would suggest more sand too, but then again it all depends on what you are going for, SSB
or a DSB
. 60lbs of sand isn't much either, it sounds like a lot on paper but when you poor it into the tank, you'll realize that you'll need more!
As for the Via Aqua Skimmer, my cousin has one and it works great but it is very very loud. 100$ for a pretty good skimmer ain't too bad. They also have a skimmer w/ a 5Watt UV
Sterlizer combination that isn't too bad but I'm not sure if 5Watts is suffient for a 72Gallon Tank.
