    Hi all, Normally Diatoms decline over time, I don't know why and I'm not sure any-one has a scientific answer for it. Cherry shrimps might be another diatom grazer?

    Can you people help me identify the type of algae on my plants?

    Hi all, Diatoms need silica (Si) to build their frustules, but after that it all unravels. Have a look at <"Any-one used the JBL SiO2"> and linked threads. Ramshorn snails or Nerites will eat the diatoms and there are also Otocinclus. cheers Darrel

    Help understanding NT Labs liquid ammonia test

    Hi all, You would have got your money, it should be 1.21. That is right, free ammonia = NH3. To take pH and temperature out of the equation scientists use "Total Ammoniacal Nitrogen" (TAN). I think TAN helps as a concept. Some aquarists will argue that you can ignore NH4+, because it isn't...

    Help understanding NT Labs liquid ammonia test

    Hi all, I assume it is just nitrogen content of NH3, although it should be 1.21, rather 1.12? It is worked out from the RAM of nitrogen (N) = 14 and hydrogen (H) = 1, so the RMM of NH3 = (14 + 3) = 17 and 14/17 = 1.214. (NH4+ would be "multiply by 1.29"). These tests usually add an acid to...

    Hi all, Yes it is only really the "lots of fish, not (m)any plants" scenario where you are reliant on microbial nitrification. Oxygen becomes even more important at that point, you don't have the net oxygen production of the plants from photosynthesis, you don't have their fixed nitrogen...

    Low-Tech Set-up and Water Changes

    Hi all, You will need to change a reasonable volume of water just to control nitrate (NO3) levels, and again this would be dependent upon having a low nitrate supply for water changes.
