I think I will try the 4 inch sand bed. Is it okay to use the cheap sand though? Like from home depot or a pool supply place?
ALSO, I need to break down and move my current 55g in order to slide the 125g in place. I was thinking on taking some of the sand from there and putting it in the 125. I will be keeping the 55g up in it's new spot until I am happy with the 125 which could be a few days to a few weeks.
Will that impact the 55g? Will it help the 125 at all? My sand is quite live and has lots of good little things living in it. But it's aragonite and not the same texture and size as pool/filter sand...
I know alot of questions, but I'm trying to do this one right.
