Please Help With Flow Ideas

[Bosco83]

I have a 210 mixed reef and I just got a 6105 from my wife for my birthday! So for the time being I will be using the 6105 on the right side of my tank hooked up to my apex. I'll be using two k4's on the left side. What would be a good program schedule on the apex? I have been searching but everyone has two 6105's that I have found. So should I have it pulse from 0-100% or turn on and off starting at 0 then go to 100%? Please give me some ideas I'm not sure what would be most beneficial?

Thanks,
Brian

I would pulse the pump from 30-100% at 3 second pulses. Avoid the speeds of 1-29%, they can damage the pump. 30% is the minimum run speed, 0% or off is also fine.

I'll give that a try thanks!

Ok so for a total newbie how does outlet control correlate with the outlet profile?

Thanks,
Brian

I don't understand the question, if these terms are specific to Apex controller terminology it would probably be better asked in their forum.

If you mean how does the flow rate change with the front housing (propeller housing) used, it doesn't. It only changes the pattern at 100% power, 24V, the wide flow housing gives a 5ft by 3ft pattern and the stock flow housing gives a 7ft by 2ft pattern.

Roger, for creating a solid wave pattern in a 90 gallon, 4ft tank, would you suggest the narrower flow pattern or the wider cover? Also, just to clarify, are you saying that you can run the 6105 in a 0% to 100% range without risk of damage or shortening the pump motor? I know when I just tried mine for the first time in a 0%-100% range, it clicked every time it started and stopped. I certainly don't want to shorten it's life, but I really want to create a nice wave pattern in my tank.

Thanks!

The only issue that arrises with off and on function is faster calcium build up and the need for more frequent cleaning. The clicking on start would be reduced by upgrading to the more recent drive unit, same part number 6105.700, but it had a change to include a shock absorbing bushing in July 2010.

I think the wide flow housing would be more effective in a 4ft tank.

Thanks Roger. I actually just purchased the 6105 from Marine Depot so I have to assume it's the newer bushing. I do know that it clicks more when using either the 18v or 24v jumpers, but not as much with the 12v. I assume that's just because of the additional "jump" of power when it kicks on.

Is there a way to see if I have the older bushing and if so, is there any type of exchange I could work out to get the newer part?

Sorry to thread jack.

If it is a new pump, it will certainly have it, it will look like part 3005.740 shown on tunze.com, the old one did not have the blue silicon cup, and is part 6065.792. This part is on the base of the shaft, you could see it in the pump with a small penlight. This doesn't 100% eliminate the click it just softens it. The click is the magnet being pulled back against the disk by the coil energizing. The other part of reducing this click is on the controller. Our 7092 and 7096 have a very short ramp from 0-10% that is a few milliseconds in length, this eliminates more of the click as it eases the magnet down when the coil is energized. The more power the coil has, the louder the click.

Ok, mine has the blue silicone part, so I have the new one. The click isn't bad, just noticeable so I was concerned with its potential damage, and am grateful to hear it will be ok going from 0 - 100%. Thanks much Roger!
