Can this be under the gravel or does it have to be submerged to the side of the tank?

I use it hanging from the side of the tank. You can monitor it better. I was afraid if it was under gravel or any rocks it might melt or make the rocks or gravel hot.

I think that it could be, but that it would hamper it's ability to heat the tank. I would keep an eye on the thermometer to determine if it was heating the water enough when it is under the water. That being said, there is no reason it couldn't be placed under a thin layer of gravel.

The intake is on the lower right side. The unit should be completely submerged.

I have mine placed just above the gravel. You need to measure the temperature of the water, not the gravel. Note it can be placed horizontally or vertically, so either way it doesn't take up much space.

It has a plug that you can empty the water into, but not a removable tank. You just need to place a container under it. It's not a problem at all.

You will need an air pump, and the gravel works best if it is 1.5 inches or so deep.

It doesn't have to be fully submerged, but it does have to be submerged up to the minimum water level line, which is right below the big black part with the dial.

It's designed to go in the tank. It might be possible to rig it up as an inline, but I wouldn't count on it being watertight.

These are very light items. They need to be held down by something heavy enough to keep them weighed down. I have rocks in my 55 gallon tank. I have it held down and hidden under one of the rocks under the gravel. The rock holds it down and it still blows lots of bubbles without any problems.

What would you be vacuuming if it was not the gravel? Otherwise, forget the whole thing and just suck the water out of the tank if this contraption doesn't allow you to put the intake into the substrate.

Not a good idea, because it has a water level line on it. you can buy the ones that you can bury but it may melt the rocks with the heat and I loss a fish due to the heaters under the gravel. I like this one cause it has a red light that shows it is on.

You would want to put this underneath the tank or in some sort of space near the tank. It would not hang on or go inside the tank.

I don't see why not. It suction cups to the side of the tank just keep it lower so your lizard can crawl onto it. It does have the top section as a "diving platform" so you might want to stack some rocks up higher so he can crawl down from it without diving off. Hope that helps.

If it's going to be submerged yes. Otherwise not really. Squirt a little silicone behind it if you want

The brand is the same as the tank, gravel I believe is extra. However I would not recommend this tank. The light is directly above the filter so half of the tank is dark and the filter gets a lot of algae due to the direct light on it. One the filter is covered in algae, this system allows the water to just pass over...so the filter doesn't work at that point.

The gravel is round but kind of large. The leaches should be fine but food tends to sink between the gravel.

The heating element is submersible but you can't put it under the gravel. The controller unit has a separate sensor that goes in the water to read the temperature. I am really happy with this heater.

You can put it under your tank in the cabinet. You don't have to drill holes in tank tubes it comes with are meant to go over the top corner of the tank.
