Welcome to AA!!
Ok, here is the skinny on that "live sand" in a bag. It is simply not true. I don't know how they get away with calling it live sand.
The bacteria that is supposedly on that sand needs food in order to live. That food is ammonia and nitrite. Fish and food breakdown (among other things) produce the ammonia while certain bacteria convert ammonia to nitrite. Neither of those is present in that bag, so how in the world can there be any bacteria alive in those things?!?
You would be better off buying the regular Aragonite sand or try to get some Southdown sand from the HomeDepot in your area. Get the smallest diameter size you can get. Then go out and buy some LR
. 25-30 lbs should do nicely if you are only wanting to have these three fish and nothing else. The LR
will "seed" your sand and overtime, you sand will become real LS
. It won't be anything like what you buy in that bag.
If it were me, I would also not use the Aquaclear Power Filter (unless you take out all the media in which case all it would be doing is pumping water). All you need is two powerheads in your system to move the water around. The LR
will do the rest.
