Oh yeah, there was a question some where in there. 'How much' is a personal preference, but both bags will get you in business. You will need to rinse the sand really well to keep the tank from being a cloudy mess. Expect to rinse it 12-15 times.
that sand looks right
rinse well like chomps said
in my diy link below is a thread about how i clean and add sand
and one bag should be fine,i have 100lbs in my 240g
add one bag and see if you like it
One bag may even be a little too much. Deep sand allows toxic gas to get trapped under it, instead of dissipating gradually. I have 50 pounds in my 75 gallon, which is plenty.
I rinsed mine once; maybe it was just clean to begin with?
I'm in Jacksonville, FL.
I think I'll start with one bag and see how it looks when it's setup.
Then I'll just suck some out if it's too much or add some if needed.
I got two new 5 gallon buckets to do the rinsing and a large tupper ware container to keep the cleaned sand in.
Thanks for the advice everyone.
I'll post a new thread with pics once everything is done.
