ATO For fluval evo 13

[GHOSTLY]

I have an upgraded pump from maxi jet that is rated 900gph. The problem is the water level in the first chamber is of course lower because of the pump. That being said what ATO is good for the fluval evo 13 and can i just fill the water directly into the tank?
This is what im looking at

You want the ATO sensor in the sump. The water line can go either in the sump or main tank. I like Tunze, but it will also depend on what you can fit in the back.

Does the water level have to be consistent for the ato to work? Also what model from tunze

you need to have established what the water level is with regards to when the ATO starts doing its thing, yes.

No. As the water level in the sump drops the ATO will kick in to "top it up" until either the float or optical sensor triggers it to stop. I think it's the Tunze 7155, but Tunze is also coming out with a new model soon. Again, it will really depend on what you can fit back there, so take measurements and then check that against the dimensions of the ATO models you're looking at.

I think he means if the water level fluctuates - which is why you need the sensor in the sump (the display will stay consistent; the sump will not).

ah. Yes you’re probably right.

Any fluval evos?

 

[GHOSTLY]

Also how do you set them up?

How do systems like this work?

I have my sensor for Fluval Evo in chamber 3. I simply turn pump on then mark where the water drops down to when on and position sensor accordingly. When pump is off the water level rises and thus ato does nothing, but when pump is running the water level drops to said level and ato maintains it there. Occasionally my clowns will hang around the overflow and cause the back chamber water level to fluctuate briefly which wrongly triggers ato to overfill lowerering
salinity ever so slightly, but it soon rights itself as the water evaporates and level gets back to where it was.

You’re aware that you need a Hydros controller for this one to work.

I have 2 Fluval 13s. One has the ‘standard’ Tunze 3155 and the other has the Nano Tunze 3152. Both fit but I wish I’d got two of the standard 3155s.

I actually did some research and I'm thinking of the tunze nano or the duolettos ato

I have the Tunze 3152 in my 13.5 EVO. It works really well and setup was fairly simple.

I use a 1 gallon cereal container I found on Amazon (like $10) as the reservoir and I drilled two holes in the lid and ran the wire/hose through it. It tucks neatly behind the tank which is on my countertop. The float is in chamber 3 with the return pump and the hose from the ATO goes into chamber 3 as well.

As far as finding the right level when installing, I just eyeballed the float relative to my water level (with the pump running) and placed it. I used a sharpie to mark the line on the glass on the side of the back chamber so I can always see where the default water line should be. Now water changes are pretty straightforward and no ATO adjustment is necessary. However, I always unplug the ATO when I'm doing anything in the tank since things like changing the filter floss, moving the InTank rack, or even using a syringe to pull water for testing can trigger the ATO by slightly changing the water level.

I'd like the additional security of the optical sensor, so I've got my eye on what Tunze comes out with next. I may upgrade to the 3155 if the new one won't work.

Did it come with everything you need

Apart from the cereal container for the reservoir, yes. It had everything needed.

im thinking between the duoletto and the tunzew nano. Can't decide. Anyone?

I had a similar pump for the Hydros, as the Duetto, and I wasn’t a great fan of the size of the hose; it’s quite big for a Nano tank.

Tunze Nano has a mechanical float valve, which can either be a good thing or a bad thing. There’s no optics to clean but it can get stuck. Mine hasn’t got stuck (yet) but sometimes the pump doesn’t turn on, which is a bit weird. Turning the unit off and on again resets it.

I still think the best ATO is the ‘standard’ Tunze with both the optical level sensor and safety float valve. It looks like Tunze might be doing away with the safety float valve on their new version, which could be a mistake IMO.

Any of those ATOs should work fine.
