Uncle Fish Posted October 4, 2011 Share Posted October 4, 2011 First off, thanks for all the information these boards offer. I am a saltwater n00b and you guys have been invaluable. I bought a used 29g biocube with about 20 lbs of live sand and 25 lbs of live rock. The tank has been running for two months and all seems well. I am starting to see what looks like pebbles on top of my sand. I have a freshwater tank with a natural pebble substrate (the small inert stuff aquatek sells for $15 for a 50 lb bag) and they look almost identical to those. I don't mind the way they look but I am worried about problems down the road. So, are the pebbles ok to keep in the tank? Quote Link to comment Share on other sites More sharing options...
+KimP Posted October 4, 2011 Share Posted October 4, 2011 I've had a bunch in my tank for 4 years with no issues at all. I have plenty of sand. I say no worries! Unless you decide you don't like the look of course... When I tried to pull some out of my tank, it was pretty easy with a slotted spoon.

Chad and Jen May Posted October 6, 2011 Share Posted October 6, 2011 You will find that as the sand settles and moves around that the heavier pieces of rock/substrate are exposed as the finer pieces move down. They arent a problem, so long as you dont mind the look of them. Quote Link to comment Share on other sites More sharing options...

nemirn Posted October 6, 2011 Share Posted October 6, 2011 Why is the penny in the tank? It's good luck. Just like a teaspoon or two of cyanide in one's morning coffee. Quote Link to comment Share on other sites More sharing options...

kmmthree Posted October 6, 2011 Share Posted October 6, 2011 Having the copper penny in the tank is probably not a good Idea. Quote Link to comment Share on other sites More sharing options...
