I have a very old metal and glass 5 gal
tank. I'm having a problem with splash I think but I'm not really sure. I start noticing a leak around day 3-4 of having the bio wheel filter running. I can't figure out where it is coming from unless the water from the splash is running down the inside of the hood and then running down the sides. I haven't noticed any water on the sides however. I have checked all the edges and the bottom for leaks. I can't find any.
Any ideas on how to fix this? Is it as simple as buying a piece of lexan for a splash guard? If so what is the best thickness to get and how would I go about attaching it to the tank? Would I be able to just sit the lexan on top of the tank and then the hood on top of that? I would rather not have to screw in anything or otherwise damage the tank (it is an antique) but for the fish and my furniture's sake i would give it consideration.
Also I do not currently have any fish in this tank. I'm just trying to make sure I have all the problems solved before I begin cycling.
