all the aragonite is in a bucket
Are you talking about aragonite? or Crushed Coral...two different things...Aragonite sand is good and is pretty much the same as Southdown if I am not mistaken...
If you are planning on doing a Fish Only aquarium, you do not have to use LR
to have a beautiful fish tank...
As far as algae goes, you can have just as bad either way and there is no proof of that...
The potential for outbreaks and possible diseases are prevelent in both systems...
In all, it will cost twice as much to go LR
as it will to just go with a wet/dry filter for FO
tank...If you plan to have corals in the future, I would suggest the you plan your tank around a budget that includes 2 lbs per gal
and at least 1 lb per gal
of sand and probably 3 to 5 pounds of LS
to seed it...
I will give the seniority a chance to get in on this here, I hope I helped...
