I picked up one of these fluval 13.5 gallon aquariums, and it has a little chamber for filtration on the back. SOMEONE ripped up the default foam block that fits in there, and it got me wondering if I could use some of that modular foam that comes in pelican cases? Or should I just buy the replacement?
Pelican case foam is typically nasty oily with god knows what chemicals. Just a heads up, from someone who used to work with it.
