    Well today was pretty hot in JHB, my JBJ Nano Cube temperature went up to 28C.

    Is this still an acceptable temperature? Can't see it going higher than this where the tank is placed.

    Thanks
    Matt

    Get a desk top fan on it, get some drinking bottles full of R/O - put them in the freezer to regulate temps in an emergency.

    Up to 28c is ok, anything higher than that - it can be bad, a friend of mine lost all his corals and nen' at 32c

    What is the temp range ie what temp does the heater come on, as you don't really what it to drop to quickly. 28 fine my one tank runs 27 -28 I find it is easer to keep it at that range in summer as it does not have a chiller.

    Usually sits around 24/25, today was really hot tho! Think it stabilised at 27.5/28C (got 2 diff readings from 2 diff glass thermometers)

    I'm not too worried about it though, will do as you suggested though Wee-Man ;)

    As Wee-man said, 28 is still okay, from 30 things get tough and at 32+ you might be staring at a disaster. A good fan wil drop your temp with up to 4 degrees, but you need to have your top up water nearby. The fan cause evaporative cooling which can cause a quick drop in water levels.

    You should be fine at 28. I have always thought that from 31 it is a problem.

    Better plan than dropping it to 25.

    Maybe in winter run it at 25 -26.

    Remember to try keep it as stable as possible.

    try and keep it constant at 28.

    its higher than i would like, bit a constant 28 will be better than fluctuations

    Well for the past 4 or 5 days its been at a constant 25, I just noticed today was particularly warm and it got to 28.

    So I will keep my heater set to 25, and if it gets hotter i'll put a fan on it (Can I have a fan running the whole day?)

    Also how long will RO water last if kept in 20L drums (out of sunlight) ??

    To be honest, in a nano, i think 28 is too high, there is no room for error, better to keep it around 26c.

    I would agree with Wee-Man and aim for 26 in a Nano the problem being the lack of oxygen in water at higher temps and if you have a fair bio load in any system this could become a problem very fast. Now a nano with such a small amount of water the problem could escalate even faster.

    Hi Matt - just something else as well - I agree with the wanting the temp to stay constant - BUT, take into account that the water temp also changes on the reefs in the sea as well - as long as the change is NOT TOO rapid, and not too high - and as long as the temp does not stay high for too long either.

    Alan made a very important note: the higher the water temp, the less oxygen in the water - this is a major problem..... so ensure that you have oxygen in the water for the life-stock (power-head that churns the water surface)....

    Nice matt, peace of mind at last. Although some of these 'gadgets' are extremely expensive it is well worth it in the long run as it gives you peace of mind and one less thing to worry about on your tank.

    Expensive in deed, I have got away with the PC fan route in/on my sump. Not really an option for Matt

    Yup, just wish this cooler was tiny bit quieter as it's in my bedroom... Oh well, it only comes on about 6 x a day for +-5 mins at a time ;)
