Hi friends, I have eczema and part of my skin care regiment requires the use of steroid creams. I'm curious if I could potentially harm my fish by putting my hands in the aquarium. (really the sump) I wash my hands after applying it, but I expect some of it to have absorbed and potentially leech into the water. I have the full arm leather gloves but anything that requires finesse is lost on them. Speaking particularly of stuff like triamcinolone. Thanks
