    Just got back from TGM...

    Remember that Brighty K also contains carbonate so will raise you alkalinity (KH) James

    Just got back from TGM...

    There is potassium (K) in both their TPN and TPN+ products. Here is the breakdown of TPN+ from the Tropica website. N 1.34% P 0.10% K 1.03% Mg 0.39% S 0.91% B 0.004% Cu 0.006% Fe 0.07% Mn 0.04% Mo 0.002% Zn 0.002%

    I lost one but it was a cardinal that was about 6 years old. James

    cloudy because of trace

    Some people have clouding problems whilst others don't. There are too many factors like light, water compostion, etc to say for sure if you will get clouding or not. Changing to another powdered Fe-EDTA based trace mix won't fix your problem. You need to dose one that uses Fe-HEEDTA. The main...

    Hardness of water comprises of 2 parts, temporary and permanent or more commonly known to the fishkeeping world as GH and KH. The 2 tend to go hand in hand so when GH is high so is KH. When you have a KH of 15+ I can tell you that a good number of plants don't do at all well. Then again some...

    I can name a couple more that I have in my tank that uses RO water. Utricularia graminifolia and rotala macrandra. In hard tap water they just die. Without a doubt this is the case. I only have cardinals but compared to when they are in hard water their colours are much more vivid. I would also...

    Can a Fire Extinguisher damage a Regulator?

    Yes a regulator can be damaged by a fire extinguisher for the reasons you have given. As long as the CO2 rate through the regulator is slow the CO2 has time to vapourise in the syphon tube that is inside the fire extinguisher. If however the rate is too fast then you will get liquid CO2 in the...

    Brain Teaser

    Bit difficult not to when opening the page as it's right in front of me. I've a large screen so can get a lot on in one go. First answer given 10 minutes after the puzzle was posted.

    Brain Teaser

    Well thank you to those who couldn't manage to keep quiet and had to post the answer, even after Dave asked not to. Just ruins it for everybody else.

    T8 alternative to Arcadia's T5 Plant Pro

    These are what I used to use - http://www.lampspecs.co.uk/Light-Bulbs-Tubes/Aquarium-10000K. Give quite a purple light very similar to the triplus/triton tubes. HTH James

    EI ratio

    Seems good to me. All you need to worry about now is CO2 and flow. James

    EI ratio

    This calculator works out how much build ups you get when adding ferts - http://www.ukaps.org/forum/viewtopic.php?f=11&t=10937. If you do weekly 50% water changes then it's impossible to get double your weekly dosing levels. If you carry on the maths you were doing for several weeks you'll see...

    EI ratio

    Generally speaking there is often a fair amount of potassium in your tapwater so you don't normally need to add any more to the standard EI dosing. The 30ppm level is normally the amount you want and not how much to dose each week. So adding 15ppm per week and doing 50% water changes will result...

    fert recipe

    The parts you are missing are the Nitrogen and Phosphorus which can be added in the form of potassium nitrate and potassium phophate. For a standard dose of TPN+ of 5ml per 50 litres you add the equivalent of 5.9ppm nitrate and 0.31ppm phosphate. So if you wished to make up a separate solution...

    iPhone Apps

    Don't forget the apps that work with this forum. There are 2 to choose from, but they both do the same thing more or less. http://ukaps.org/forum/viewtopic.php?f=5&t=9979 http://ukaps.org/forum/viewtopic.php?f=5&t=11322 James
