For your sized system (and good to see the planning going into it BTW) the 70l air pump will be heaps. I had over 12000l of water, and was only running a 20l air pump as backup. Put around 6 air stones spread between your tanks, and you will have plenty of air. Probably overkill

The 20l air pump did over 450 fish for over 12 hours quite easily. I just pulled 2 trout out of an IBC that has had no water flow for the past 24 hours (thought it was empty of fish) with only 1 air stone, and they were fine. Water was at 25 deg c too. Airstones do a very good job of aeration, despite what is often thought.

System is shaping up nicely Adzza!

Just checking OBO - thats a 20l/min pump? (not L/hour!)

Had a funny moment trying to find a 20l/hour pump and not finding anything less than 100lph
What size would you think for a 6000l system? 10l/min? And would you run it just as backup or continuously?

6000 l/hour's a good starting point.
that's 100 l/min

but you need to be able to achieve this at the head you want.

Pumps state two things, the maximum head (with 0 flow)
and the maximum flow at 0 head.

Both these figures are misleading in many ways, as they are the extremes of functionalily, and are never going to be your operating point.
Work out how much head you need to pump. Then check out the graph or table on the pump to see how much flow you can get at that head. remember long pipes reduce your head.

Kuda ,, I think you meant long pipes INCREAsE your head.
Note: Elbows , sharp turns etc are EVIL for increasing head resistance

Well as it currently stands I would need to pump from the sump to the secondary tank which I would do via a pipe running uphill attached to my fence. Probably a distance of about 20 meters. I beginning to wonder if the ebara optima pump is up to the challenge. From other systems and reviews I would think so, but who knows....

Outbackozzie

The optima will do that nicely. Air pump wise, yes it's a 20l/min

Uses 20w, and runs from the inverter continuously.

The amount of backup air you need depends greatly on how many fish you want to keep. I seem to recall TCL saying something about a formula, but I can not remember it.

I'd probably go a 40 watt piston air pump, never have any air related problems then.

I was actually considering the 150L/min pump

More air cannot be a bad thing right? Or maybe I should get 2 X 40L/min and use one as a backup.

I use the ACO-008... 100L/m.... 6000L/h.... for my 6000L trout tank...

With all 12 outlets running... it looks like a spa... :wink:

adzza

Excellent. Looks like 100L would do the job easily for me.

Are these air stones any good?

Also, anything else I should order whilst on this site?

Cheers.

Also, are these pumps loud? Annoying?

RupertofOZ

Nah... just a bit of a hum.... mines outside, not that far from the neighbours... no complaints...

adzza

Sweet. Can anyone recommend good airstones?

Chappo it depends on how you frame your statement, and it's perspective.
long pipes increase resistance, therefore giving your pump a lesser head than quoted. ie, running a pipe a very long way horizontally, means it wont be able to pump as high, effectively decreasing the head. As I stated above.
I don't want to get into a pedantic argument with you, but if you're going to correct ppl, try not to agree with them, and just write it in a different way. After all you can't be correcting them if you're just paraphrasing.

Outbackozzie

Just normal air stones adza, and that size air pump is way overkill. Your just wasting power unless your putting 10,000 fish in their.

Kuda .........., "whatever"
