jn Posted December 3, 2007 Report Share Posted December 3, 2007 Danz, the temp depends on what fish you want.. some like it hotter than others. Look up the breed you want in a book or on the net and work out a group of fish that prefer similar temps (although tye're all pretty adaptable I think) Quote Link to comment Share on other sites More sharing options...
Danz Posted December 3, 2007 Author Report Share Posted December 3, 2007 sweet one more question how long will i have to wait after i put the heater in. the tank has been ticking over for about 1 1/2 weeks unheated Quote Link to comment Share on other sites More sharing options...
Ianab Posted December 3, 2007 Report Share Posted December 3, 2007 Yep, 25deg is a good average temp for the more common fish you will probably have, but different species prefer different ranges of temps. Hilstream loaches and White clouds prefer the temp down around 20deg, while Discus would like up it close to 30. But 25 would be a good average for most common tropicals. Dont believe the numbers on the thermostat either, 90% of the time they wont be correct. Plug it in, leave it overnight and see what temp the tank actually is in the morning. Then adjust a couple of clicks to where you actually want it. Cheers Ian Quote Link to comment Share on other sites More sharing options...
jn Posted December 3, 2007 Report Share Posted December 3, 2007 with 100w in 40L the tank will heat up pretty quickly.... probably this time of year the water is reasonably warm to begin with.. if yo have any fish in there already.. put it on its lowest setting and crank it up slowly by 1 deg./day.. if you don't have a thermometer you should probably buy one...if you search the forum you'll see plenty of stories of heaters going nuts.... heating all the time or not working any more.. so beleive yuor thermometer (plus or minus a couple of degrees...there not mor accurate than the heaters sometimes!! :lol: ) Quote Link to comment Share on other sites More sharing options...
Danz Posted December 3, 2007 Author Report Share Posted December 3, 2007 hi back again next question the box says the heater should be straight up and down but i would have thought that laying heater across the tank would have heated more even.

tHEcONCH Posted December 3, 2007 Report Share Posted December 3, 2007 hi back again next question the box says the heater should be straight up and down but i would have thought that laying heater across the tank would have heated more even. Thats how I have them - so long as it is a 'fully submersable' heater it works fine. Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted December 3, 2007 Report Share Posted December 3, 2007 Unless it says it is fully submersable it should be straight up and down with the cap at the top out of the water and the rest in, or it may leak water. Quote Link to comment Share on other sites More sharing options...
Danz Posted December 3, 2007 Author Report Share Posted December 3, 2007 i have an aquaone 100w it says submersable on the box so any way will be alright then Quote Link to comment Share on other sites More sharing options...
