Can root tabs be harmful to fish if they become uncovered? I've got corydoras digging around where I've put a root tab, and I'm just worried about it leaching iron and metals into the water :/
meegosh said:I think the big thing would that if you expose the root tab it will probably start to release nutrients into your tank, causing an imbalance. You may see algae outbreaks or even spikes in your water parameters. They should be buried enough into the substrate that a cory wouldn't be able to dig it up, IMO.
