6100s on Tide Mode + Small Fish?

[tanglovers]

Hi All,

I have been talking to Roger back and forth about my new Tunze setup. I have two 6100s in a 100 gallon tank. They are positioned approximately straight across from each other on the sides.

I wanted to gather some opinions here as I am wondering if I am being paranoid. I have some small fish that are always darting in and out of the rock. I am worried that if I have the 6100s set to completely turn off....the tide mode....the small fish may swim int here and that will be the end of them when they kick back on. Has anyone ever had this happen? The small fish I have are 1 cleaner wrasse, 1 neon pseudochromis and a mandarin.

Roger recommended the tide mode and I do feel that may be the best setup I am just worrying. Right now I have it so they pulse from high to low flow alternating back and forth between the two.

Also if I do the interval setting, how often should I have them switch....currently they are switching I think every 5 seconds. This seems to me to be a little too often....any ideas? If I need to change it how do I do that on the 7094?

Any opinions/experience would be appreciated.

Thanks,
Scott

I've got a six-line that just loves to swim in and out of the 6000's when they're not running, so I stopped using tide mode for that exact reason.

Dave P -

How do you currently run your 6000s? How do you have your multicontroller set and are you happy with the flow rates in your tank?

Thanks,
Scott

Well, I'm not UNhappy with the current setup, but I still want to experiment, as I'm not convinced I've found the ideal. It's a 60" tank, and right now I've got the two 6000's on magnet holders on each side, with the flow angled toward the front center glass. Lots of flow, as I now see hardly any detritus on the rocks when I do my weekly turkey baster cleaning act. This flow pattern has totally cleaned all the sand from the center front of the tank, which doesn't bother me, but I'm sure others would see it as a problem.

I've just added a large green carpet anemone, so I may be modifying the flow pattern to a position where it's happiest. For the first week, it's stayed close to one of the streams, but well off to the side.

I'm running the multicontroller, of course, but for the time being I have both pumps on the same pulse pattern, alternating 100%-30% or so, dropping to night mode with the photocell when the lights are off.

Scott, if you have the new driver 7240.27, the pumps spin one rpm every 20 seconds to scare fish away. Otherwise, the pulse interval can only be set between 1-7 sec. % seconds is just fine. The interval between pumps is the knob on the right and it is set in combination with the switch but it only works in sequence and tide modes and has no impact on pulse mode, the shortest possible interval is 1min.

Hi

Thanks for the input

Roger - our drivers are the 7240.26 - the ones listed on your spare parts page of your website. Are the 7240.27 something really new? How much if I wanted to get these? Do the 7240.26 spin at all to scare fish?

Thanks,
Scott

This was a new feature we added to the driver in the summer, the website is a bit behind. It is driver 7240.27 and they aren't cheap, $92 each, that is the most expensive part of the pumps. Honestly I would get the 7095 controller which has a program that solves this problem or wait till we have another solution we are working on.

so that's why they kick on for a second every once in a while. i was wondering why they did that. good thinking! i figured it was some sort of electronic hiccup.
