Is a 4,500lph pump to big for a 1,100lt tank?

Nope

You want to turn the tank volume over once per hour. ie 4000lph pump @ 15 minutes on 45 off,
or 1000lph @ continuous. Its up to you what you want to do, but an energy efficient vortex pump 65 watts is good value, and silent. I actually run mine as much as I can (just need to limit overnight for temp) keeps the water much cleaner than a small pump.

Personally - go the big pump.

Can you link us to an example oba? I'm going to be looking for a new pump for my big system before the end of the year. I will need something I can run continuously and obviously power consumption will be a big issue for me, as will be throughput. I reckon to allow for expansion, I'll want to be able to pump at least 6,000 litres per hour (genuine) at a couple of metres head.

6000 lph (slightly bigger than mine)
95 watt (bet you wont find better for the capacity, I tried)

I got mine from Joel

Extremely recommended I am very impressed with the performance compared to my cheapy ebay pumps.

Yeh - saw that one on that other thread. Pumps less than 3000 at 2 metres head though. I'm thinking I may end up having to run a small pool pump to get what I want.

Growbeds on your roof?

Jebao 10,000 rated at 4080 litres at 2.5 metre head $195.00.

I dont think you can find a better pump for AP than the jebao tornado's, value for money, power consumption, all good And they are soooooo quiet.

I think we forgot to answer my question, I am looking at a jebabo 4800 litre pump I only have about 1200lt, I know I only have to turn water over once an hour, so is it over kill, well yes it is over kill but is it 2 much

What head ,, what pipe size ( additional head ) that is da question:)

I answered it in my first post??? The bigger pump gives you more room to expand, gives you a lower running time and is generally all good.

If you have a sump, just make sure it can keep up with the other pump.

If you have a pump in the sump , why would you need another pump???
Almost poetry that ,, pump in the sump, in the sump pump.

Fish tank pump to grow bed. Grow Bed drains into sump (gravity). Pump from sump to fish tank.

Gravity from tank to grow bed ,, gravity from grow bed to sump ,, pump from sump to grow bed:)
