What would be a good heater for a 75 gallon reef tank? I was looking at the 300watt Rena Smart Heater.

that would be fine i use 2 as i have a sump and a high flow and live in a cooler climate

That's the same brand that I use. I like them a lot. I also have 2 of them sitting in my sump.

I have used both the Rena's and visitherm stealths. Both are good heaters. In my case, I like the Rena best simply because I have Rena canisters on my tanks that the heater connects to.

I use the Rena and have been quite happy with it....

Would I be better off buying 2-200w or 250w visitherm stealths or one rena smart heater? I can buy two stealth for the price of one rena. Or would 1-250w stealth be plenty?

On a larger tank I would rather have 2 than 1 simply for a backup if one of them failed.

I prefer the Visi-therm Deluxe to the Stealth just because I can see the light that lets me know the heater is on, where as the Stealth doesn't have a light.
