I kinda thought about that. Of course, from their non-coppered water. But I was concerned about any diseases. If the sand is from one tank, linked to 20 other tanks, how concerned would you be about checking each fish in each tank for white spots?
I'm, leaning towards shrimp cycling for the full # weeks it takes. Then, in one day, adding the new sand, a large old rock w/xenia from the main, small pcs of cured rock, and maybe a single cup of sand from my main (for what at this point, I'm not sure -
input pls if any one will). Probably within that week, adding a fish. Most likely a small rock hugger. Then a few smail hermits.
Oh yeah, w/the new sand, I'll also add some of that to my existing tank. Need to fashion a funnel of some sort to add to the rear of the tank in areas I can see thru the rocks. Darned pistol shrimp!
Any holes in 'da plan? Improvements? This is intended to be a xenia (and maybe other small coral) farm. I just gotta remember that as I go along and not treat it as much like a real tank with fish being the focus.
