Thanks for your response.
I am steering away from a full-blown reef because I had so much bad luck with my last one. Seems more time was spent worrying about the rocks and the sand and the water than was spent enjoying the fish.
If I go with a FOWLR
with let's say 20lbs of LR
in a 40 gallon tank, what should the substrate be? Can it just be plain old sand? Can I go ahead and do Live Sand, or will it all die off since I don't have Live Rock.
Also, I thought of this last night - Can I just put regular rocks in my tank? Do they have to be Live Rock? Can't I just put in some sand and then some nice base rock and call it a Fish Only tank? Down the road, can coral or an anemone be placed on base rock, or do they REQUIRE LR
Sorry for rambling on and on - I just really don't get how live rock and live sand play their part with fish. Is there ANY form of marine life that REQUIRES Live Rock or Live Sand?
