Hey Daniel. I've been following Andre Mueller's Reef Moonshiner program (
@PSXerholic ) for the last few months and the use of a power filter is highly suggested within the group for his system as well. I switched from "sometimes socks/sometimes not" to a modified power filter within the display tank and here's what I have noticed:
The good
- My water is much more clear with very little particulate matter.
- Much less buildup of detritus within my sump.
- A slight increase in PAR at depth.
- I don't feel a need to run socks any longer, which means no more changing and washing them.
The bad
- Aesthetics - having a pump and filter in your display tank is noticeable. You can run it in the sump, of course, but I didn't have sufficient room and it seemed to me to be less efficient.
- As the filter becomes clogged the pump will start producing microbubbles (this is actually my indicator to change the filter wool)
- Purchasing and having on hand disposable filter wool (as opposed to reusable socks).
Overall I'm glad I implemented it as it has made a noticeable difference in water clarity. It's amazing how dirty the wool becomes in a week.
