Neutral cure silicones do not give of acetic acid, generally methanol or some other alcohol type. There are many silicones available, both neutral cure and acetic acid that contain no fungicide, that may be used in a fish tank, data sheet often lists not harmful to aquatic life, but in the end genuine aquatic safe sealants don't cost too much so are the way to go.I thought all of them do, only the bathroom ones contained antifungicides
Wooow. Except that this contains fungicide with is lethal to aquatic life according to MSDS paperwork. Its LD50 (lethal dose to kill 50%) is in order of 5mg/l so quite toxic, as would be expected for a mould resistant silicone.That JBL stuff is simmular with excact same specifictions to Tec7 polymer. Only the price is different
€ 14,95 for 80ml JBL VS €10,- for 310ml TEC7.
