heaters

crf9 · 10-14-2005, 12:02 PM

Does anyone know how important it is to keep the water level at the water level line on aquarium heaters? I just bought one and the line is like at the tippy top of my tank and I can't fill it up that high.

I have heard it is very important that it is up to the line, but I've been running mine for months with the water about an inch below the water line and it has been doing fine.

PS. Did you mean to post this in saltwater?

No I wasn't sure where to post it, my tank is brackish. Thanks for the info. I think i'm going to run run mine too about an inch above the water because my fish's water is way too cold for her right now.

in a lot of books and fish stores brackish is considered fresh.
what do you have in the tank?

I have a green spotted puffer.

I have run my heater about 1-2 inches below the water line and its always worked just fine.

Speaking about heaters though, are the heaters for saltwater the same brands as the ones you would use in freshwater. What are the best heaters to use in saltwater tanks.

They're the same brands, and indeed, the same units. There aren't many "saltwater" heaters anymore, although there used to be a few decades ago when metal & salt creep was a problem. Nowadays they're all pretty much the same, waterproof & impervious to salt creep under the control knob.

NO, I take that back. The units which are cheap & bulky and made strictly to hang over the edge of the tank are not waterproof if submersed. The units which don't have the big hanger-heads and are submersible are much safer for saltwater. Either type works fine, though.

As far as I know it is important. If you don't have enough water to cover it, it will be the same as operating it out of water. In that case, the heater will break - either electronically or even physically

always ran mine 2-6" below waterline but any lower than 6" seems to reduce the gaskets life

The heating element in a hang on tank heater is toward the bottom of the glass tube. If the aquarium water level is so low that the glass above water line heats up and a splash of water hits it, it may shatter. I think that is the main danger.
