Aquabee 2000 and tunze 6045

[BigMouth]

Hi guys, i have a tank 2 x 1 x 1 tank (55L) and a 20L sump. Plan to get a pump to suck water to protein skimmer and outflow to my sump.Since the sump is placed higher than display tank and water will gravity fall back to display tank. The pump will place out of water condition. So is aquabee 2000 enough for producing bubbles for skimmer? Does it with needle wheel propeller? Or any other suggestion

Another question. Which wavemaker is suitable for my tank, Tunze 6025 or 6045?

Thanks

tunze 6025 will be enough for your tank, if you find it too little to your prefernece, you can cut the cover to get more flow (can search around to mod 6025 to 6045

whats the skimmer for your tank? any pic of your setup for us to advise further? cos sump normally is placed below the tank, if yours is above and letting it flow downwards to the display tank, a picture would be better for more bros to advise "better"

Thanks for the 6025 mod information. I will try on this

I am using the aqua macro skimmer JS100L (http://www.aqua-macro.com/skimmer-b.htm) As the manufacturer stated that the max is 1800L/hr. But i think to get a 2000L/hr pump for it. Should not be any big problem??

Sorry bro. I do not have the sump tank yet as i am looking for better price for this custom-make sump. So far had 2 shops quoted me, $80 and $90. Any shop recommend? I have the drawing for it which attach below. Hope this will help

Bro, it's difficult to visualize from above description. Can't tell if your skimmer body is sitting in the display tank, or in the sump, or hanging outside both tanks.

(1) If the main purpose of the sump is just to house the skimmer, then you're going thru' too much trouble. Instead, just getting a HOB skimmer for your tank would do the job.

(2) Every off-the-shelf skimmer is designed for certain pump specs. Example: An in-sump skimmer design may not skim well if you place the pump out of water. You may have to trial & error with different pumps.

Sorry for confusing you. I am using HOB skimmer and only 1 pump will be used for the whole system. Let me clarify more how my system work with the diagram below.

My display tank will be placed lower than my sump. Piping will connect from display tank to the pump's suction (which will be placed out of water) and pump's output connect to skimmer directly ( hanging outside of sump tank). Then skimmed water will flow to my sump and finally back to display tank.

Thanks for showing the diagram. It's much clearer now. Below is what I can see from this setup:

Pros:

- Pump running out of water contributing to less heat transfer.

- Lower power consumption due to skimmer pump performing 2 functions. (i.e. skimmer + return)

Cons:

- The higher placement of the skimmer will definitely requires a stronger pump. (This may cancel off the power consumption benefit above)

- You'll need to prime the pump every time to get it started.(Your pump will be damaged from running dry after a power outage)

- Difficult to secure pump at edge of tank.(Pump contacting glass may be noisy)

- Pump & skimmer requires regular cleaning since detritus flows thru' them before mechanical filtration in the sump.

- Flow rate in sump is low as pump is sucking in more air than water.

Pros:- Pump running out of water contributing to less heat transfer.- Lower power consumption due to skimmer pump performing 2 functions. (i.e. skimmer + return)

Thanks for listing out the pros and cons. There one more advantage why i placed the sump tank higher is because I will build a refugium in the sump as well which could provide natural food sources for my main tank.

Cons:- The higher placement of the skimmer will definitely requires a stronger pump. (This may cancel off the power consumption benefit above)

Is Aquabee 2000 enough for this situation?

Why did you say so?

Yes, I'm all for the use of refugium too.

Like I said, it depends on what skimmer you're using. You need to trial & error on this.

Why did you say so?

ok, you can perform this test to see for yourself.

(1) Setup your skimmer with original pump in a bucket of water.

(2) Turn it on & observe the amount of water coming out of the skimmer outlet.

(3) Detach the pump from skimmer & connect pump's outlet to a flexible hose.

(4) Turn on the pump in the bucket of water & observe the amount of water exiting the hose.

You will notice (2) gives you much less flow cause much of the work is used for creating bubbles.

Okay, I got it !! No choice as you said, need to try and error for the pump. Thanks for your clarification
