Decomposing rubber toxic?

[VJV]

Hi Randy, hope you are doing great.

I have a Tunze 9001 skimmer and some power heads in my QT tank which o regularly sterilize with bleach (about 5% solution). I have noticed that the rubber around the magnets seems to “melt”, loosing color and becoming sticky after a 24h bath. Could this be toxic for the livestock?

Notice the bits of rubber that stick to my hand just by holding the magnet in my hand. It is very stickie and almost glued to my hand.

Happy holidays!

I would guess it's not an issue, especially if you use GAC. Most random organic molecules are not an issue at reasonably low levels.

Thanks! Not sure what the levels are. My concern is whether it will become toxic in combination with some of the meds I use in the QT, namely cupramine.

Also, I do not use carbon all the time because otherwise it would remove the mess as well.

I still wouldn't worry.
