    Cheap 79p one from the local discount hardware store.

    The glass type with the little balls in the bottom end. (Same as the £2.50 Hagen Marina ones ;) )

    Accuracy isn't that important. A degree above or below is not going to make any difference to the inhabitants. A few degrees maybe.

    There are the tiny ADA style ones on ebay for a good price. they are only about 3mm wide and 5cm long. Very unobtrusive and with blue indicator fluid rather than red.

    I have 1 of them too. lol For my 10 ltr. I'll put it in the main tank later next to the larger one and take a picture for you.

    Ok here are the 2 together.

    The one on the left is the standard one which is repackaged by all the companies and sold as their own. Cost from the Supermarket was actually 99p and not 79p as stated before. These are the same as the Hagen Marina ones.

    Next to it is the crystal ADA style one which was £3.50 off ebay.

    If they were both in the tank for any length they both read the same temperature at nearly 26C but the large one has been out of the tank for a while and therefore when replaced is reading lower as it hasn't got up to temp yet. Therefore I would suggest they are both accurate.

    However the little one does look better and surprisingly is much easier to read. I also like the blue in comparison to the red. If you right click on the picture and then select open image you can see it a little cleare and the difference really shows in 'readability'.

    I've used the battery type and I was satisfied until I took my own temperature with it. It said that I was at 95.4 degrees, compared to a normal 98.6.

    I decided that it was close enough and went to bed.

    I have a substrat heating system that is computer controlled so I just use the display of that comp.

    I also have a other digital meter that I use in mine soon to be replaced nano cube.
    I gone give the Tylomelania a bit more growling space :)
    And maybe add some Sun dadanio axelrodi Bleu to that new tank.

    Why digital?
    Wel I find it so much easier to read.

    Well mine is never yellowish and pretty clear anyway but Purigen plus 50% weekly water changes pushes it to a little clearer. Plus 5500K pure white lights.

    I wouldn't worry about accuracy too much. 99% of thermometers are going to be accurate to within 1 degree C which is easily accurate enough for our purposes.

    More O IME makes the water clearer :)


    I wouldn't think reducing the lighting would make a difference to water clarity unless you were getting algae spores in the water column and now the lower light is meaning the plants are now outcompeting.

    IME = In my experience. IMO = I my opinion.

    The more O was to mean that if you have a decent ripple and/or pearling = more O in the water....oxygen .

    So in my experience more oxygen in the water gives a better clarity. Unproven, non scientific but seems to be the case from my observations.

    I use the ATI stickers that go on the outside of the tank that react chemically to temperature. Since you can place them at the substrate level, you don't notice them really. I've tested them against in tank thermometers, and they seem to be accurate enough. Only problem is my cat ends up tearing them eventually, but they still work even after that.
