Can I place my heater in the sump reservoir? I'm curious if anyone has done this or tried it. It's no big deal, I just though it would be easier to get to and also hide it as well. Thanks!

Well, upon further investigation, it appears that my sump isn't deep/wide enough to fully submerge the heater. How much of the heater must be in the water? I don't have anything in the tank now, so I suppose I could just play with it to find out if it will heat properly or not. Just wondering if yours goes all the way in...

Wow, so many "that's what she said" lines in that paragraph.

Most heaters are designed to be fully submerged. Evaporation is going to cause the water level to get lower and lower and if you start out with some of it exposed, chances are one of these days you might find an overly-exposed heater that's fried or cracked.

What model/brand is yours?

Ahh, so physical damage to the heater is a worry. Then I'll just leave it in the tank. It's a definitely meant to be fully submerged, because it is now, but I'm not sure what brand/model at the moment.

If it was an old heater that came with the tank I would just replace it. There's a long history of old used heaters malfunctioning and cooking tanks.

Or not heating tanks... I had an old heater that I thought was working and wasn't... Let's just say my clownfish didn't like 55 F water... luckily it wasn't my cuttlefish tank.

Eh, well I live in Florida. I'm not too concerned with it getting too cold. I have the heater all the way down... it's December... and the water is 79 degrees. Guess I'll be looking at a Carribbean species :)

I would suggest leaving the heater out of the tank altogether if you are in FL and don't keep the AC on high. They are really not the best thing to come in contact with for curious critters of any kind. I am in the N. GA mountains and have only recently decided I needed a heater in ONE of my tanks because the sump is in front of a window. If you can pickup one of the inexpensive Coralife thermometers (nice little digital for tanks) they are easy to read but a stick on works too. Monitor your tank at different times during the day and see how much it changes (early AM will likely be your coldest but monitor for your hottest too to check your daily fluxuation). What you WILL likely need is a PLASTIC clip on fan over the sump to keep it cool during most of the year. The fans can be found anywhere from a couple of dollars to around $35 for a double fan built for an aquarium (I use several different kinds).

Yeah, I think I'll just be removing it. I may need it for two weeks a year at the most, but I agree with you that it isn't necessary and could get the little guy into trouble.

One of the first accessories I purchased was a Coralife digi thermometer :)

One more question... as far as substrate, what would you guys recommend? It's currently a sand/crushed coral/shell mixture.

I have tried several and found that the most recommended has been the best, a THIN layer (1"-1.5") of argonite sand. It is the easiest to clean and my nitrates have been much easier to keep under control since I switched.
