Enough GPH???

[mathias]

55 gallon tank

I got

fluval 404 = 340 gph
other filter = 200 gph
powerhead #1 = 238
powerhead #2 = 238
total = 1016


so divide that by 55


1016/55 = 18.5 times an hour.....


hmmmm sounds like a lot when I was adding it up hehehe :)


another question these powerheads I have right above the sand and its blowing the water pretty good now I feel like my snails are in a hurricane should I put them up top?


LET ME KNOW.....

[mathias]

no but Im kind of a power user hahaha I want MONSTER water movement hahaha I do want some corals and soft corals....

[mathias]

well two powerheads are on the bottom #1 is bottom back left corner #2 is bottom right front corner then two filters up top moving all the top water.....

To check your flow characteristics, try putting some brine shrimp in the tank and see how the currents take them. Borneman has some inches/sec figures that are more useful than the gph count. they're in his aquarium corals book.

8540/240=35.80 @ hour. Now that is flow!
