heater top temps

[Irene0100]

I have a 90 litre tanks (approx two and a half feet long) with some zebs in. I recently realised I was not getting the temp near 30 C that I wanted. the heater was a new 200w jewel set at max. so I added a second 200w older jewel also at max. bothe of these would come on when tank below 27 but would stop when got to 27!
So just bought a rena smart heater and removed the 2 jewel ones. it is happliy at 31 C now and its not turned up to max either.
anyone have similar probs?

I have always binned my Jewel heaters after finding them unreliable

well these have worked fine but dont get really hot (so useless for zeb breeding. In my big community trigon I bought a new jewel one too as knew the heater was 4 years old so might be vunerable. I like the fact they sit inside the filter housing so fish dont get burnt. Anyway the new jewel heater is fatter and does not fit in the housing any n more!! So it is in the tank not the filter housiing, I am waiting for a heater guard I have ordered but hey the BN has already burnt himself!

Well that will be why I found them no good for my needs the Jewel tanks I had them in needed to be at 30oc and like yours they never quite made it

Use a heater of 300 watts and a Eheim 2126 thermo filter set the internal heater at 30 and the thermo filter at 27

I just noticed that my fluval heater was changing temp whenever it wanted so I binned it and got a eheim jager. Very good heater and temp is very stable
