Have a 90 gallon tank that has no hob filter or overflow setup on it (it is piped for overflow/sump, just don't have one yet). I have a small hob filter that clears up all the particles that float on the surface if I put it on the tank but I am told not to use it.. So is this ugly stuff on the surface a big deal?
