That would be a "REEF ONLY with LR". Let me 'splain...
My kid likes my 29 gallon reef. He's getting bored with the elong in his 55 gallon (that's a type of pirahna), and wants to switch it to a reef. I keep telling him he doesn't have enough money, but, of course, he won't listen to me.
I've told him the basic rule of thumb for LR is 1 to 2 pounds for each gallon of water. So, since his mind is ALWAYS working, trying to figure out an 'angle' to everything, he says "Well, what if I don't have any fish? Just corals? You TOLD me that corals don't add nearly the bio-load to a tank that fish do, so I must not need that much live rock if it's only a reef, corals, and NO fish!". I, of course, being the wise old dad, told him "It don't work that way". But, him being him, won't give up, and want's me to ask on this forum. So...
How much LR would be needed for a "ROWLR" tank?
Sorry for the rambling, but that's what happens to me after having a discussion with him...
