Temperature drop

[harrow]

Hello fish friends

Since its getting cold outside and I have no control over the apartment building heating, my fish tank temperature drops from 76 during the day to 72 at night is this to dramatic for my fish?

don't you have a heater in the tank?

[harrow]

yes i do but it cant keep it stable

During the day the light keeps it at a good temperature and the room temperature is also warmer

How big is your tank and how many watts is your heater? if anything, it won't hurt to add another heater to the tank if it gets too cold!

In my 75gal tank, I have two 150watt eheim jagar (one on each end of the tank) and that keeps my tank stable at 82 degrees F even in this cold winter... and in my house... I can't really up the heater too since if the heater turns on for too long my nose gets all stuffed up... so I have it at 20degrees Celcius (approx 68F)... so in my case having 300 watt of heat evenly distributed in the tank was enough to keep it stable at 82 degrees

its only a 10 and i believe a 25 wat is the dropping temp to much for the fish

Depending on what fish you have, it might be too stressful especially for more sensitive ones. I'd say a 50 watt is probably what you'd want for something around 10 gal...

I highly doubt that the temperature drop will be too detrimental to your fish in a 10g tank. However, sounds like your 25W will not be able to keep up with the heat loss.

Why not add another 25W or 50W heater in there so you can sleep better That is just the cost of losing a few fish - or the cost for medications when problems develop. A heater at $20 will last you for years.

25w is not enough for a 10g. That is usually for tank 2.5g to 5g. I would get a 100w for your size of tank.

We have some new one for $20. Check our equipment section for more detail if you like.

thanks for the help, just been really busy with the semester starting spending my time and money, so i was just worried about my fish as the season gets colder. Hopefully my fish will last this little cold period because by the time I get one the snow will be gone. But charle i might have to come down and buy a heater
