Issue with UNS all in one

A while back I set up a UNS 60A all in one. It’s one of those tanks with a divided chamber in the back with media and pump. I “upgraded” from an AquaJapan version as I didnt want the curved corners anymore.

So the AquaJapan had the normal intake vent at the top on the divider, but it also had a few intake holes at the bottom for when the water gets low. The UNS does not have those bottom intake holes. Ok..so just always be sure the water level is above intake, right? Wrong. When the water levels gets a little lower than halfway down the intake vents, the back chamber starts getting really low. My heater is in the back chamber, sp this is an issue.

I emailed UNS, but never heard back.

I am sick that the tank I had BEFORE worked better. Any advice?

I see 2 options here. 3 if you count tearing it down and getting rid of it.

#1 - get a set of glass hole drill bits for about 7-10 bucks and cut a 1/4" hole lower down to work like the other tank. Cost - some time and 7-10 bucks

#2 - get a Automatic top off system with an optical sensor to always keep the water level where you set it. A small 3-5g container will probably last a week or 2 before you have to fill it again. Cost $100 or more depending which system you buy. A DIY container to hold your top off water will save a bunch

Thanks. Top off system is a really good idea. I worry about when we travel, so this would ease my mind.

Drilling it would be the BEST choice, but I am not up for draining and starting all over at the moment. I know I would break it in the process as well. Ugh. That’s probably the long term goal (drilling it, not breaking it)

I was really scared to drill my 68g UNS90U but it ended up being a really easy process. I also did it with fish, plants and about 30 gallons of water in it. If you're gentle and let the hole saw do its work you should be fine unless it's tempered glass. Most of the problems i hear about are the thinner glass of mass produced tanks.

I agree that the ATO system would suit you well if you're gone a week or more at a time.

Use this an use a dog food container for the water.

Put the pump container in the tank stand. The container will hold 5 gallons of water. The sensor goes into the camber where the return pump is.

How did you keep the Glass dust out of the water?

I didn't. I used a powerhead and hose to keep the hole saw cool and the glass dust went into the tank as a very fine dust. It's non toxic and the water cleared up with filter floss quickly afterwords.

Thanks. I guess it’s different for fish...no lungs.

Bump: Just heard back from UNS and they said “we will consider adding lower intakes in future models. Please ensure you keep the chamber filled”. Oh well, thanks UNS. Thanks for nothing.

The more I think about this the more upset I get. This tank design is a safety hazard. Every other all in one aquarium has lower intake holes for this reason. Someone is going to have a fire because of this design.

I shouldn’t have to rig up a $100 top off system to my already expensive UNS tank. UNS doesn’t seem to care either. They will wait until someone has a fire to do anything.

There’s no way I can successfully drill the holes myself without completely emptying the tank and turning it on it’s side as the glass needing drilled in INSIDE a small tank. UGH

This is the standard way that this tank is made. The UNS tank is a standard AIO tank made in a Chinese factory.
https://www.innovative-marine.com/

Innovative marine is the largest sellers of AIO tanks. You can get an ATO or top of the tank yourself it is up to you.

I have had AIO Tanks in the past so I know the issue of an ATO.

WOW, I had no idea as every AIO I’ve had in the past has had bottom in stake holes. Fluval, AquaJapan and Marineland. I haven't had am Innovative Marine.

There a ton of AIO tanks and very few have a bottom intake. All AIO tanks need and auto top of system really due to the way the back cambers work.
Especial if you want worry free aquarium.

My IM doesn’t have any lower intake holes. If I don’t fill it once between water changes the sump will run dry. The chambers the media and heaters are in always stay full though

The center chamber on a IM will lower as water evaporates. You install the ATO there and you water level will remain the same.
