if you havent noticed, i have bad luck with heaters. well inmy 5.5 i have a 100w i got very cheap brand new at pet supp plus. it was a decent name but i cant remember the name of it. well ive been using it for awhile but when i did a wc today i must have forgot to unplug it. it worked fine all day but when i got hme i looked closer and noticed i have a little water in it. i took it out and realize i have a small crack on it, its not broken yet, just cracked, i put some aquarium silicone on it, do you think this will effect it? im gonna buy another but from big al's, i just wanna make this one work for a few weeks.
