Taco Posted November 25, 2020 Share Posted November 25, 2020 Looking into substrate alternatives when I thought of blasting sand, as it comes in 50lbs bags for about $12. But considering what the sand is used for, will it bother any fins or gills? Specifically Black Diamond blasting sand. I plan on putting a couple fancy goldfish and maybe some Corydoras into a new tank and want no issues. Anyone use this before? Link to comment Share on other sites More sharing options...
Daniel Posted November 25, 2020 Share Posted November 25, 2020 It would seem safe. Black Diamond Blasting Sand is not really 'sand', it is coal slag. Here is what that means: The tank with Black Diamond Blasting Sand is labeled 'Dirt' and is the middle aquarium: The fish in this tank seem as happy and perky as the fish in 'Nerm' and 'Eco'. 1 Link to comment Share on other sites More sharing options...
RovingGinger Posted November 25, 2020 Share Posted November 25, 2020 The only issue I have run across is that my blood parrot seems to get a chunk stuck in his lip from time to time. 1 Link to comment Share on other sites More sharing options...
