Thanks for the link! That article has certainly made me take another look at my system. In goes the Resun Waver 15000 I have had lying around for some time.

Installed the Waver, within a few minutes my Blastomusa expanded. Makes you think?

Well I come from a FW background, so when I set up my tank I thought I was loosing it, I installed what I thought was massive return flow @ 4800l/h and added in 2 x 620 and 2 x 1100 seios.. I thought I was waxed, but as I have gone on, I find that I am now upgrading my flow inluding a 5000l/h closed loop and the 620's are coming out & being replaced with 1100's

I find it makes for a happy tank, not to say that low flow tanks don't have their place, but my system will be SPS dominated.

Hi Alan - how much flow do you have in your tank at the moment? I have +-23000 litre per hour (+-36 times turn-over)..... BUT, I have a Reo-Sun 15000 l/hour power-head connected to a wave-maker......
I would love to increase my flow, though..... have 2 x Reo-Suns or perhaps the Reo-Sun and a decent Seio (10000 litre per hour).....

I have 2x6000L Seio, 2 x4000L Seio all running on flip flop timers. A closed loop with a AM 6500L actual flow about 4000L Ph with the head loss and my return at 8000L ph actual flow from return about 3000L Ph with the head loss.

About 1200. I am not a person that believes in massive water flow, rather a good flow well placed to create random flow, this is mainly because of the LPS in the system.

Alan, When you say on a flip-flop timer.... doesn't it turn the pumps on&off completly?
Isn't this bad for the pumps?

Alan I am also interested in the flip flop timers. I believe one can get them with what is called "soft start". This kinder to the pumps.

Alan/Rod/Shane: I got a timer with my ReoSun, which is an alternative to what you have (actually it is supposed to be a "wavemaker timer). It switches between different power-settings to the pump, for a pre-defined time. The time the pump stays at a specific power-setting, is changed by turning a reostat knob.
Having two of these timers and the two ReoSun pumps then creates alternative currents, depending on how strong the pump is "blowing" at. The ReoSun pump works with a actual propeller-blade, very much like a propeller on a boat - it does create a HUGE current at the timer's strongest (full-power) setting. This is an alternative to the actual "power-off/power-on" timers you guys are talking about.

Any thoughts on this?

Jacquesb I am using a Resun Waver 15000, I installed it yesterday. I like very much. I have ordered another.
I have set the three stages at minimum.

Hi Rod - that's the exact same one I have (I actually meant ReSun, and not ReoSun :)
And I have ordered a second one as well - I currently have the 3 power-heads in my tank (of which one is the ReSun 15000). I want to replace the 2 smaller p/h (one=4000 l/h and the other=2500 l/h) with the 2nd ReSun 15000 - where both the ReSuns would be on the Wavemaking timers.... (I also have my return which I rate at +-1500/1700 litres per hour from 2 pumps: 1 being 2000 litre/hour and the other 1900 litre/hour with a head height of +-1.2 metres)

I was asking because I could build a flip flop circuit very easily but the soft start function would be tricky.

The resun wavemaker has a DC motor think 24v not checked, the normal seio is AC220. The only correct way to control the speed is using a pulse width modulator. The seio M1100 and up has a controler you can buy think around R2000.00. Still trying to find out more info on them. DC motors are very easy to control the speed.
