setting up the rd3 9000 pump

[runetspike]

hi guys.
My display is 500 liters, the samp is 200 liters.
I bought a return pump rd3 9000, do I understand correctly that it should work 50% on my volume?

Set it up and adjust it to whatever flow you wish to have through your filtration (your sump!) Not sure what you mean by 50% of your volume?

I aim for 8-10x my tank volume every hour (500 l tank - so 8-10,000 l/hr) but thats much more than most people would aim for. It's recommended for the Triton Method.

Adjust your pump to 3-4 times turnover (1500-2000 l/hr) and adjust as required.

should my pump be running at 100%?

Your pump should be running at whichever % that gives you your desired tank turnover! No one can tell you whether it is 10% or 100% - that's up to you to measure..

Your RD 9000 has a theoretical flow off 4000-9000 l/h depending on the setting. By reading that, under optimal conditions you should get 4000 at the lowest setting and 9000 at the highest setting.

If you can attach a hose to your drain pipe, you can run for a known period of time (lets say 30 seconds) into a bucket of known capacity (lets say 20 L).

If in 30 seconds you fill the bucket with 20 L = 1 minute = 40 L = 60 minutes = 2,400 L.

You get it? Works with any flow rate / any capacity you want. The math is the same.

You can start at one of the lower settings and adjust as you see fit

the flow rate, how does it affect nitrates?

It does not.. Not directly at least.

I was told that siporax may not start due to the strong flow of water in the sump. My pump is running at maximum. So I started thinking about setting up the pump.

I was told that siporax may not start due to the strong flow of water in Samara. My pump is running at maximum. So I started thinking about setting up the pump.

I have never used Siporax- so that you will need to ask someone else about i'm sorry! Might be useful to have a look through this post!

i was going to buy one of these. are they good

I bought it, but I don't understand how fast it should pump the volume. Someone says that it will be enough for me to use it at 40% of its power, someone says it needs to be unscrewed to maximum power.
