I had sand in one of my tanks and it played havoc on my filters....The problem is if you have a fish that kicks up the substrate (ie CatFish) you'll be dealing with filter issues. Thats just my experience....
Hello All!!!
I'm looking forward to share the passion of Asian Arowana with all of you.
At present I own a nice Green, as anything beyond that is out of my price range at the present.
Cheers!
