    Has anyone tried these heaters? Are they reliable?

    I haven't, but I will be, only because we are having solar panels installed next week. And even then only during the day when I can run it for free. 1.5kw per hour at 48cents (in SA) = $1036.80 over the winter quarter, if run 24/7. I'd rather have that money in my pocket

    JBC is right on the costs of heating. That is one of the costs of AP and it needs to be minimized as much as possible. Fish choice can help a lot with that.

    With regards to heating water, I found it to be a double edge sword of sorts. Heating the water causes increased evaporation which results in higher humidity which can cause you issues if AP is indoors. Just a watch out. I've changed to heating the total environment - part (or most) of the heating being from dehumidifier that recycle the water back to the tanks.

    If you must heat the water itself, direct solar heating into the water using an exchanger design is the most economical option.

    Hi Robert, not meaning to hijack jbc's thread, but have you tested the water from the dehumidifier, I have herd it can contain high nitrite and ammonia.
    I would be interested in the results
    As for the heater JBC are you sure you need one? SE Queensland doesn't really get that cold unlike here in the Riverland, we have had two weeks of-2 deg minimum an my 10/SP are doing fine
    My water temp has bottomed out at 10degC
    I'm currently trialling a direct solar
    One good tip that Terra gave me. If running a bell siphon, remove the bell during cold nights
    This stops the cold air being drawn into the GB. This is good for retaining at least a couple degrees

    Never tested the water - been doing this for years. Doubt seriously it could cause an issue in the system because of ammonia / nitrites (it's not THAT much water) but I'll test simply because you've sparked my curiousity.

    Im in Ipswich and gets in the minus temp in the mornings, this is for my next setup were I plan to have Barra in it looking to use heater as a backup but as I think about it more I might look at running multiple 300watt to spread out heating across tank plus gives more redundancy if heater fails

    Hi JBC,

    I grew barra here over the winter in one year using two 300 watt aquarium heaters for 1000 litres of fish tank plus similar amount of media for the grow bed.
    A couple of observations for you to bear in mind.
    • Your grow beds act like giant radiators so when it is wet cold and windy you will lose a lot of heat from them.
    • I found over night on the really cold nights it was best to shut the grow beds off last thing at night and turn them on 1st thing in the morning. The critical thing here is your water chemistry so checking the water at night and morning is a good insurance policy.
    • 22C is minimum tank temp to keep the barras metabolism working properly 24c is ideal, less than that you need to keep a close eye on their health, 20C is the coolest I liked my tanks, I didn't like that and I killed 1 baara at 17c grrr I hated that.
    • The electricity cost wasn't that much more, I can't remember it being much of an issue, but it was a consideration.
    • If I had that time again I'd probably go for another 300 watt heater.
    • I did it once and was quite successful, but I did spend quite a lot of time keeping an eye on the fish when it was cold. I grew about 19 beautiful plate sized barra in 12 months.
    • I wouldn't do it again, rather, keep my heaters adjusted to the same temp grow barra for the summer 6 months and then harvest and in winter, take out the heaters and grow rainbows for the winter six months. I grow lovely small but good sized fish for both species.
    BOT I couldn't talk about the heaters you speak of as I have never tried them.

    I hope this helps.

    Cheers

    Did you consider using a compost heap with watertubes in it?
