A little trouble with my new IM fusion 20

Just set this up last week and I am having issues. My middle chamber back water level is much lower then the other chambers so much so that with a little evaporation it's sucking air. Is that normal for the break in period or is something wrong?

Thanks for the replies. I have the tunze 3155 attached and working to keep up with the evaporation.

 

Display tank water is about an inch from the top, still shooting bubbles. Add more you say?

The middle chamber will fill up with any water you add. Do it asap so you don't burn out your pump

 

Your ato sensor needs to be in the middle chamber with the returns

 

Here is my Fusion 20 rear setup.

 

Left overflow. Media

Left 2nd chamber. Heater

Middle chamber. Return pump. ATO Sensor. ATO fill

Right 2nd. GFO Reactor

Right overflow. Media

Took a quick pic of the water level in my Fusion- about an inch lower than the over flow from the previous chambers.

 

Top of the pic is the ato fill line. Bottom black tube is my ato sensor. Same chamber.

 

Hope it helps.

Thank you so much! The pictures helped immensely, for some reason I couldn't wrap my head around adding the water directly to the middle chamber. Did that, switched the ATO and micro bubbles are gone!! Now ATO seems to not be working correctly, it just fills and fills.

well id test your salinity and adjust accordingly then re- place the ato to where its at a good salinity and good water height. because things may have shifted in the time being.

always always always top off an AIO in the rear chambers. And not an in take chamber. Set your sensor in a non intake chamber, you can raise the water level before hand by running the filtration pump(s) and adding new water to those chambers till the desired level is reached.

 

So it fills and fills and floods the aquarium or not?

I have the Tunze too. I have found the same thing if the optical sensor is already in the water when you plug the ATO in. Either take out a little water so the sensor is above the water line then plug it in or set the water level a little higher. It took me a while to work out what was going on. What I did was unplug the ATO overnight so the water level dropped from evaporation, set the sensor to the right height and the plugged it in. It ran until near the top of the tapered section of the optical sensor and then shut off. The other thing is you can adjust the flow rate with the dial inside the control box. I had it set all the way to the left for a slow flow but with the height of my table, it wouldn't go at all so I had to dial it up a little. If the flow rate is set high, it'll fill faster but may overfill in a smaller tank. HTH

The ATO didn't flood as the back up stop/alarm worked correctly but the water went well over the sensor. I'm going to try what GTi suggested. The sensor was most def in the water when I first plugged it in so I'm hoping that's the issue.

The tunze 3155, will always do a "purge" upon start up. As soon as the power gets turned on it, it will pump for approx 20 sec. If your water goes above the optical sensor, just leave it alone. It will work itself out. Just mount it in the return pump chamber and stop messing with it.

Yea I'm familiar with the plug in purge. It's still trying to fill after this and even after the water has gone up and over the optical sensor. Trying a dry start now....

Here's what I do.

 

Unplug ATO

Do maintenance, pumps off

Turn on pumps

Wait a minute, plug in ATO

Block water from getting in the tank (with a finger covering tubing) for 10 seconds until the purge is over

Also make sure your top off water line is NOT in the water. This will create a back siphon once it pumps and just continuously run your top off. It needs to be out in the air.

So I'm still having issues with the ATO. I thought it was working with the dry start but now am confused as the water is over the top of the sensor this morning. I can't remember it looking like that. Does salinity affect the sensor?

 

Also top off tube is not in the water.

Is your sensor upside down? The tip of it should be facing the water, the wire should be facing upward.

Salinity shouldn't affect the sensor.

 

Is it clean?

 

The stock pump, not the outlet upgrade and a different pump?

 

What fill speed is it set to? Is it possible it just overshot a little?
