Uneven filled tank

[fazendas]

Hi,

My Nyos G2 300 already arrived and today I filled it for the first time.
After filled I spot a difference in water height, from back to front(from left to right is okay).

This is something for me to worry about? It's my first tank and it give me some worries.
The tank has 12 leveling feet, but with the tank full its impossible to access them.
Should I empty it and try to level it again?

Thank you.

I would definitely empty and re-level

OK. Looks like about 0.5cm, which ain’t much. However, if all that is in the tank is water, you should drain & level.

On stands without leveling feet, I used tapered shims which were easy to install with tank full.

I just emptied and re-leveled my 70g. Even though local experts said it would be fine, we felt it was just a better thing to do than have regrets later!

Absolutely drain and re level, you really want it level for this journey. Many reasons for that but it’ll be easier to do this now then later. Took me 2 hours to get this one I have leveled perfect between all the little legs lol it seemed you’d change one then others would pop off the ground lol patience and it’ll be much better when your done!

I would have to level it if for no other reason than it would drive me crazy.

Not sure if your system is like my WB 330.7 or not. I removed the sump which then allowed the floor inside to be removed so I could get to the all of adjusting feet. I had a few inches of water in the tank for weight and didn't have to readjust any after the tank was filled.

Definitely re-level this tank! — 70 gallons of saltwater is nearly 600lbs! (Incorrect support can literally “twist” the tank apart at the seams!)

I also recommend getting at least a 2ft long level, if not a 3-4ft level for doing this task… you will get far better “resolution” than your current ~2in long bubble provides!

Thank you all for your input.

I will empty it and try to level it better.

After 3 hours split between 2 days, the tank is finally leveled. The floor near the wall is higher than the center of the room, but with the tank so close to the wall, I couldn’t access the feet from the back of the stand. It was tiring and not the best experience I’ve had, but it’s done — the tank is filled again!

Now I’ve come across another problem. I just set up the equipment and I’m testing everything before adding salt to the water.
While testing my ATO, I first tried putting the end of the tubing into the top of the ATO container itself so it would just fill itself — and that worked fine.

Then I placed the end of the tubing at the top of the sump, above the water level, pointing toward the return chamber. It worked, until I realized it didn’t stop.
My conclusion is that the ATO reservoir is higher than the sump, so it keeps siphoning water from the reservoir (video below).

I then tried putting the end of the tubing back on top of the ATO container, but this time pointing toward the return chamber. It worked, but made a mess with splashing and noise.

How can I fix or bypass this problem?

Thank you!

Add a T fitting at the highest point in the ATO fill tubing, add 6-12” of tubing sticking straight up in the air off this tee…

The added vertical tubing will fill with a few inches of water when the ATO pump kicks on, then it will start sucking air like a Venturi!

— once the ATO pump turns off, this vertical tubing you’ve added sucks in air, breaking the siphon which the pump started in the ATO fill tubing!
