Aquarium Advice Regular
Hello,
I recently setup a tank. It's a fairly standard configuration with an external canister filter. I used RO water remineralised by adding salts (specifically a product called Osmose ReMineral+). Two weeks ago I added decorations, plants and bacterial additives to start the cycle.
3 day ago I added several corrydoras, and few guppies. They are now dying like flies. Testing the water I cannot see anything wrong. Ph is 7.3, and practically no levels of nitrates, nitrites and chlorine.
This morning I discovered accidentally that the black sand that I am using is ferromagnetic (the sand is clearly attracted by a magnet) meaning that it contains fairly high doses of iron or nickel. The bags of the sand are clearly labeled "aquarium/terrarium friendly". Could be the sand the origin of my problem? I ordered a water metal level test through mail, but it will take several days before I receive it.
What do you think?
Cheers
Luca
