Finally getting around to starting my 65 gallon build. Its been about 5 years since I've had a tank set up, and this will be my first tank with an overflow. I tried to keep my rock work away from the glass on all sides, so I can clean easily and minimize dead spots. I'm about a week into the cycle and so far things seem to be working out okay. Levels are where they should be, diatoms unfortunately are in bloom, but that's just part of it. I have noticed that when I change out my filter sock it always seems to slow down the flow into the sump. Is that normal? Or should I be using a filter sock with a bigger pore size to keep this from happening? These are generic 2 micron socks off amazon.
