You can have one of mine for $25

Ive got 2 of these. They both look identical. The one that I got from the auction site is very noisy and the one that came with a heap of second hand fish gear is very quiet.

I have 3 sewellia lineolata and 5 Beaufortia kweichowensis that i am planning to put in this tank

It Depends on the river that you are trying to replicate. This is just version 1

I decided to make a smaller version for my first attempt. I also decided to use poly pipe instead of pvc to keep the cost down. I started with this: Pipes and fittings $15 and a beer just coz BY the time the beer was finished Intakes and sponges added After another beer the power heads were fitted. 2 x 300lph at $12 each from the auction site. The wine is my wifes I promise. Fitted into the tank Gravel, Rocks, Wood and Water added The tank has approw 50L in it. With 2 x 300lph power heads I am pumping the volume of the tank 12 times per hour. There is some backwash off the intake wall but it helps to create some nice eddies and current variations. Total cost $39

A couple of these might be good. What do ya recon? http://www.marineandreef.com/Rio_Seio_P ... i00862.htm

I recon making a manifold system would be far cheaper and also double as a filter

Bugger Bugger. Can't sleep. Got up for a cuppa and a fag. L144 have just spawned for the first time (yeah) I agree with Stella. Ira perhaps you could give me the benefit of your infinite wisdom and discuss this manifold design and we could start a new thread re: pump head.

All fish will eat these if they are hungry enough. Don't feed them for a week or two. Problem solved.

Agreed!! But the higher the head, the less the pressure, hence less the flow

I forgot flow rate or litres per hour. Obviously the lower the pressure the lower the L.P.H.

All pumps have 3 major variables. Lift, head and pressure. Lift: how high will a pump lift water from below itself. Most aquarium pumps do not need to worry about this as they are nearly always below the surface of the water. Internal of external, gravity does the job. Head: How high the pump will push water above itself. Pressure. The higher the head the less the pressure.

From aquariumpros.com "Head pressure" on the other hand is more complicated. "Head" may be simply defined as any resistance to the flow of a pump. When pump manufacturers list the head pressure, they are referring to the vertical discharge pressure head. Described in very simple terms, a pump's vertical discharge "pressure-head" is the vertical lift in height (usually measured in feet of water) at which a pump can no longer exert enough pressure to move water. At this point, the pump may be said to have reached its "shut-off" head pressure. When you look at a flow curve chart for a pump, the "shut-off head" is the point on the graph where the curved line becomes horizontal as the flow rate at that point is zero. The higher a pump's head pressure, the more powerful the pump

Thanks for the info. Great video too. I was thinking of perhaps doing this to a couple of smaller 100L ish species tanks to keep the powerhead size down. I'm definitely going to set one up for hillstream loaches and I would like to do a more tropical tank as well. But haven't decided on species yet. Any suggestions?

I'm going to make one of these. http://www.loaches.com/articles/river-t ... old-design Has anyone else made something similar and how did you like it? Cheers

And if your tank gets infested with koura you should get a large eel

Here are a few pics taken shortly after they arrived. They look a bit pale but i think its due to the stress of the trip. Three of them definitely have odontodes but I'm not sure about the other two. The two that don't have odontodes also seem plumper. What do you think? i will take some better pics when are settled in.

I paid a little bit more than that but was happy to do so. Apparently i have purchased 3 males and 2 females. Here's hoping. I will have a better idea when they arrive tomorrow.

I see that there is some of these on that auction site. I realize that they are fairly common and was wondering what was a realistic price per fish and how hard they are to breed. Cheers

Thanks guys. Is the double tail gene dominant or recessive? Is he worth breeding from?

I am curious to know if this is a deformity or a recognised tail type with a name. Any ideas? He is the only fish from this spawning with a tail like this.

Each tank is 600 wide, 350 deep and 300 high

Thanks for the info. I had alraedy planned to get an electrician in to make it safe. Cheers

Ive heard that putting a bale of straw in the pond will clear it up.

Yep and got it thanks to this site too. http://www.fnzas.org.nz/fishroom/fish-r ... 33322.html
