Thermostat heater “settable” at less than 22 degrees centigrade reqd.

[ClownLurch]

My current tank heaters minimum settable temp is 22c. I’m going to need a one settable at 20c for WCMMs etc soon i hope. Any recommendation? Hopefully room temp will be enough but I wouldn’t want to be without back up.
Thanks.

Fluval e series is a great heater. Temp range is 20c - 34c

What else is in the tank?
If you only have white cloud mountain minnows, you don't need a heater and they are fine in cold water down to 5C.

Guppies at the moment but after three months of fruitless searching I’ve learnt of a few possibilities this week.

What size is your tank ?

Only ask as these heaters come in different wattage so if you have 100 litre tank then you need at least a 100w heater, basically 1w per litre.

I’ve had these heaters, they are pretty good, easy to read LCD and has coloured display to quickly show if water is cold or too warm.

Pretty reliable too as I had one in a tank for 4 or 5 years with no problems.

Turns out it was settable to 20c which is what I’d initially bought it for. Our hard water had crusted up the adjustable piece which I only realised when taking out of tank and rinsing it thoroughly then wrestling it to 20c.
Ive now got an unused spare of the one Charley recommended!

Keep it, you never know when you'll need an emergency replacement...........(Hopefully never.)

Don't forget to test it. Just because its says 20c ...
