I am in the process of setting up a 10g marine tank.

I have already set it up with an undergravel filter, and a thick layer of crushed coral. Water has been added, and half the salt. The heater is going, and temps look good.

Question:

Do I NEED a powerhead, or will the undergravel filter create enough water motion?

I'd get a powerhead, saltwater tanks like a lot of circulation (for the most part)! Smile

OK leave the ugf in there just don't have the bubler on for it. hook the bubbler up with a bubble wand to make some water circulation or use the bubbler and air pump in a cheap air driven skimmer. you will DEFINATLY need a water pump(powerhead) and it is recomended to have the entire tank water moved around about 6 times per hour. so you will want a pump that provides about 60gph of water movement or 225 lph.

Thanks guys...

I got the powerhead last night, and it works like a champ. I had already set up the ugf with a hefty pump on both tubes with a wand that gets to the bottom of the tank. Circulation looks real good now.

You might consider converting that UGF to a reverse flow format; certain powerheads are capable of this adaptation. The prefiltered water will help keep your gravel bed stay cleaner/less clogged for a longer period. As it is, the UGF will work well for you for about 18 - 24 months before the gravel becomes self defeating/in need of replacing; you can do this slowly in thirds or quarters. Vacuuming the gravel monthly will slow this process a bit. Nevertheless, this veteran solution will provide you with a forgiving and stable fish system for a long time with little headaches except for pesky rising nitrates. Add a small skimmer after 6 months or so to export organics... or use the 10 for quarantine and get a 29 - 55 gal for your display.

you can get a extra part for your power head that turns it into a reverse flow helps maintain free substrate prevents clogging
