Maybe PM Willito and find out where he got the larger ones.

Steve,

Are you sure you had a sand bed at this time and not crushed coral or something heavier yet?

I'd be realy interested to know how you had that much water turn around and no hard current.
I mean I know you can direct the flow from the pump in any direction, but how do you prevent having a torrent of current in a 3 foot tank with that much flow?
Do you have the powerheads behind a big pile of rock?
Maybe the tank has 3 or 4 pounds of rock per gallon of water that works as a baffle system?

Do you use a wave maker type of set up on the Tunzes? (If so, then the off time has to be figured into your gph figure.)

I'm still wondering how you don't have any hard current with that much flow.

Some of my fish (CBB and Yellow tang for example) have a real tough time maneuvering around when their in the path of the 820 in a 3' tank and more flow would surely make it that much tougher for them.

So please tell me your secret. :smile:

yup 230 LBS of sugar sand, right from salt water connection.


Define hard current? when I had it all in the top 1/2 of the tank there was lots of hard current, but no jet blast.


basically the Tunze went across the length of the tank pointed at each other, and then the 4 maxi jets intersected the tunze. and my return, returns via 6 1/2" nozzles.

No that the sand bed is gone I have one tunze on the top back left side blowing across the top of the tank, one tunze on the bottom right size blowing across the bottom, one Seio on the top front left side blowing across the tank and one Seio under the back bottom right side of the rocks blowing under them to remove the crap from under them. the strongest current is across the front bottom of the tank and the tang loves going down there. it is still slow enuf that he could hover there and eat algae off the bottom when it was there.

with this set up you can put your hand anywhere and all you feel is a gentle push on your hand


I reduced my rock to about 150 to 170Lbs of rock in a 94 gal tank. only 1 Seio is under the rock and that is to flush it out


Nope a normal wave maker will kill a tunze also. and the ones I have are not set up for that use. all water movers are on full 24/7

there is a current, but one that is the size of the whole tank not just a nozzle blast.


I find that hard to believe, in the ocean the currents make my tank look like a joke and they still manage to swim there. My yellow tang used to sit in front of the Tunze about 2" off and hover there and the 820 is only 1/2 the flow of the tunze.

We just receive the new seio 1100 and 1500 now in stock
