I have no fish and only plan on adding maybe two small fish later in the summer

Do you mean a dead shrimp - or a live pair of cleaners??

[Detritivore]

hi bomber, im going to set up a room divider, with one side "in-wall" style(im just gonna know a hole in the existing wall) and the other side regular cabinetry style.

the tanks probably gonna be 72 long, 30 wide, and 20 tall (about 187 gallons). the thing im stuck on the most, is the flow. i plan on going either with eductors on a 55rlt placed exactly like yours near the overflow, or two tunze streams...which would be better?

[Member No. 1]

This is a 75 gal with 2 peductors on a closed loop run by a PanWorld PS150 which is the same as a 55RLT. If you went with a 70RLT, bettrer nail those snails down!
Notice the bubble fly by! Sorry for the sparse stocking, it's only a few months old.

thats a nice video! i never knew the eductors were that strong!!!

[Detritivore]

are both of them on? or only one?

Both

[harsaphes]

why would i put dead shrimp in my tank?....are they easier to keep?

[Member No. 1]

Don't have to feed them!

[jdg]

Neat!

Because they have really neat personalities .

And you never loose them , they stay right where you put them ...


What kind are you thinking about ?

[Bomber]

Sugar low.

[Detritivore]

so bomber, do you think i should do the tunze or the 55rlt?

[Briankook]

I'm not Bomber, but the 55rlt will push eductors like a champ, go with that. Keep electricity out of your tank.

I have never been within 500ft of a tunze in my life, that I know of.

[Detritivore]

LOL...well, eductors sure are less expensive...my return pump will be pushing around 2000 gph, it is not pressure rate cause im not gonna put eductors on it...i was wondering why you use a pressure rated pump for your return?

As in return pump from sump? If so, think "Low Flow" Do the hi flow in the tank with a closed loop

[Detritivore]

yea, the return from the sump is non-pressure rated. if i do a closed loop with eductors, the pump will be pressure rated

[Bomber]

I tried a ampmaster that's not a pressure pump at one time. By the time it makes it's way through the plumbing back to the tank, it's poor. The Iwaki100 blows it away.

[tankslave]

a pressure rated pump is just a pump with a flatter response curve. It maintains flow rate up through higher head pressures. Its like a truck with low-end torque. Flatter response. I've had the penductors for sometime now. There's no miracle to them. Its like putting your thumb on the end of your garden hose to squirt it further. You are putting a small nozzel on a pump that can genterate a lot of pressure, thus increasing the output velocity. Just restrict the return in anyway, and you will speed up the water velocity coming out. Its not the nozzel that is doing the work, its the pump. You are just making the pump work harder.

Everyone looks at the video and says, there's a lot of flow in there. Yes, but there are plenty of tanks with much higher GPH, and look as stagnent as a swamp. Its the velocity of the water that you are outputting that makes the difference!!!

GPH is not the whole story.

harsaphes, what lens is that?


Bomber, i'm starting to question why i'm using a UV. I looked at my skimmate under a microscope at the lab the other day, and it was full of zooplankton and phyto plankton (lots of green creatures, lots of moving creatures). So i'm wondering what we are trying to accomplish by using a UV? wouldn't it be more benifical to let all the plankton grow, take up nutrients, and then be removed by the skimmer??

UV doesn't make it disappear. What size UV are you running? Did you notice more skimmate after using it?

I would have to disagree. Eductors/penductors work by not only restricting the flow coming from the pump (increasing the pressure) but also by sucking in more water around the nozzle to create an even greater volume of water coming out. That is how you can increase the flow rate without an eductor by up to 5 times with an eductor. You can't increase the gph a pump puts out by sticking your finger over the output.

That is my understanding of how they work anyways. I've never used them personally nor have I even seen them in action yet, except for the vids that people have posted.
