Heating

Hi

I need to heat a bare discus tank of 460l. the sump is 95 litres, making 555l in total

Jaeger 300w = 600l - 1000l
jaeger 250w = 400l - 600l
jaeger 200w = 300l - 400l

should i heat the aquarium with 1 x 300w heater or 1 x 250w heaters or 2 x 250w etc?

 

I would say... seeing as you live in one of the colder parts of our country... Go for the 300W option. I asume that you will be moving a high volume of water per hour (6-10 times tank volume) through your sump. Taking into consideration the size of your tank you should be keeping your temperature easy with a 300W. However if you are intending to move 4 times the tank volume or less I would rather opt for the 2x 250W option. My 5c worth... HTH

 

I would go with the 300 watt option. I've used many Jaegers and find them very reliable.
Don't pay more than R300,00

 

2 is like a safety net so I say 2x 250W option

You never know when a heater might go in the middle of the coldest winter night.

 

@Juddy... You are probably right. I use two 300w Jaegers on my 2m for that reason, but I am seriously neurotic.

Do you know anyone that supplies 250watt Jaegers... Just as a matter of interest?

 

i vote go one 300watt, if cold around outside. better 2x250watt

I use only one 300w Jaeger on my 2m tank (-+ 850L),Make sure qaulity out factory jaeger. It was around R360

 

I would vote for 2x300W Jagers, 1 in display and 1 in Sump as a back-up.
Tune the 1 heater slightly at a lower temperature as the other and it will act as back-up when the other heater should fail.

 

Our forum sponsors can assist you to find them

 

My pump does 2500l per hr so im turning the tank 4.5 times per hr.

 

well actually less beacause my return to the tank is at 1.6m high

 

Thank you all so much for your input.

 

i would say 2X 250w heaters, someone on the forum once suggested that the one is set a few degrees lower than the other, so that if the one fails, the other would kick in and you'd also be made aware of it, by seeing that the back-up is on. i think that is a good plan.

 

I agree with spider . one in the sump and one in the tank , i run both my 6ft tanks this way . but i would get one 300 w for the tank and the 250w in the sump as a back up to save costs .

 

How deep is your sump and tank, because those 300watt jagers are very long.

I agree with spider.

 

a 300w will fit in my sump i made sure it would when i made the sump. I would like to keep everything out of the tank though!

 

@bruno_mad I run my 250l discus tanks on 1 300w Jagger and it seems to be working fine at 30-31deg constant temp, were it comes to backup heaters I have 5 lying around (not jaggers if you were wondering) as I believe every one should have back up’s and if any discus keeper is worth his salt you are always checking your tanks way to many times in a day than is absolutely necessary anyways so you will see a fluctuation. The only time I put in one of the backups is when I go away or know the weather is going to be really bad but then again the cape temp hardly ever drops lower that 5-8 deg at night and discus can withstand a gradual temp loss as far as the prof has told me till about 23-18deg min but then you have to bring them back up just as gradually again. @DirkBellstedt correct me if I am wrong please.
So I would sagest getting to 300w and use the cheepie that you prob already have or get one as a back up for when you think is necessary, You are going to need it for heating you water change water in any case.
Well that’s my suggestion.
