Do ziplock bags break down in tank water?

Makes me suddenly think the sump is a good place to hide things

I would imagine at some point it would probably break down at the seams first.

As an aside, I seem to have one of those clear containers that strawberries come in wedged in the back of my tank under a rock. I was using it as a frag holder a number of months ago. I'm not quite sure how it managed to get back there without any frags in it but then again who knows. I'm not quite sure how to get it out without tearing the tank down so it may just have to live there for awhile until I move the tank. Hopefully it isn't doing anything crazy in there

christy, flexible plastics are much more reactive than stiff plastics and decompose much more slowly because of it.

well thats good to hear. I'm still going to look at getting it out this weekend. Nothing like finding something in your tank totally out of place and unexpected (not like a bonus coral or bonus frag or something ).

i would like to say i was hiding something, but i'm not i've put sponges in them and used them as plugs in my filtration chamber. It restricts the flow directing the water more at my media. It is my fowlr, and not my reef so i'm not going to worry. we store our food in in anyhow, and considering i won't be around in a few hundred years to watch them break down, i won't worry!

Please take the Zip-lock bags out of your sump!!!!!

I used them to hold soil for plants in a palidarium I set up and within 6 months they started to break down and turned into slimy goo
