6000 outlet Size

[Ben_qld]

I am running a Stream 6000 on my 90G

No matter where I place it it blows my sand around

But If I could add a 90deg bend to it, or even a 45Deg bend it would stop it blasting the sand.

What is the outer diamater of the outlet, as I can machine a plastic part to enable me to hook it to a 2in 45deg bend.

I understand this will reduce the flow, but as it is 7000lph for my 300l tank gives me 23x turnover, so I can handle up to about a 25% loss of flow

It is a standard metric PVC size, I need to look it up but you wont have to make anything if they sell metric PVC in Australia.

50mm

So I should be able to grab a 50mm pressure pipe, which is supposed to have a 50mm ID, and then this should slip over the outlet of the tunze.

I want to put about 30cm of straight pipe onto it and then maybe a 45 or 90deg bend so that I can put the stream at the back of the tank pointing upwards, and then put a few rocks around it to hide it so the only thing visible is the 2in 90deg bend shooting water out.

Will this cause any problems with the stream ? The rocks will be placed so they are easy to remove for cleaning, and also, the stream will be about 10 - 15cm off the sand bed.

Am I correct in assuming I will get about a 25% reduction in flow from this ?

It will reduce the flow but it should be OK otherwise.

Be sure you can get at the pump to clean it, if you don't clean it every 3-6 months you will ruin the pump.

What actually wrecks the pumps when they are not cleaned ? assuming that there is no bits of sand or anything that gets caught in them

So you recomend taking the pump out and giving it a good scrub and cleaning the impeller every 6 months

They lock up with calcium deposits. A pump will always have a bit of heat and a slight vacuum inside and this degasses CO2, raising the pH in a small area and lime precipitates. The tolerances in our pumps are tight so they just can't handle neglect. It will literally lock itself up solid with lime and you will have to send it in to have the drive unit removed. 6 months is the service life to expect with normal parameter 380-420ppm Calcium and 8-12 dKH. If you run a higher level I would check them at 3 months.

ok thanks, I will have to put a reminder to check / clean all my pumps every 3 months as last time I checked my Ca was around 450ppm

I would just check them at 3 months and if it isn't bad you can go 6 as long as you don't make any big channges in your supplemetation.

another question, My stream is Dark brown, yet all the ones I saw on the net were black. Is there a reason its a different colour ?
