    Where is the Bacteria?

    Hi all, It is back to variables really. With sand the waste material tends to sit on top, but with traditional aquarium gravel, uneaten food etc. can fall through the interstices (gaps). You can ameliorate for this to some degree by keeping Malaysian Trumpet Snails (Melanoides tuberculata)...

    Where is the Bacteria?

    Hi all, That is right, you can potentially get substrates that are anaerobic and N2 gas is produced from the <"anaerobic denitrification of NO3">. If you go a stage further you can get an anoxic substrate where <"hydrogen sulphide (H2S) is produced">. I don't want my substrate going anoxic...

    Where is the Bacteria?

    Hi all, It is difficult to quantify, because there are a lot of potential variables. We have to make some assumptions and even a microscope isn't very useful. The recent findings of a whole kingdom of unknown nitrifying organisms was done by <"looking at microbial RNA for Ammonia oxidising...

    Reliable testing methods?

    Hi all, They aren't cheap, <"dissolved oxygen meters"> would also fulfill the "reasonably accurate" criteria, but are another expensive bit of kit. <"Semi-quantitative titrimetric methods"> are likely to be more accurate, particularly if they include standards and you follow <"the scientific...

    Hi all, It is a really pretty flower. "Water Crowfoot" is the easy bit, but there are lots of very similar species, usually differentiated by quite subtle differences (flower size, presence of floating and submerged leaves etc). I've seen the Pond Water Crowfoot (Ranunculus aquatilis) for...

    Hi all, It is a "Water Crowfoot", probably "River Water Crowfoot" (Ranunculus fluitans). It is an indicator of good water quality (in the chalk stream it is growing in), but it isn't suitable for a warm water aquarium. cheers Darrel

    Hi all, I think all water companies have the option for chloramine dosing. The EU limit on <"faecal coliform bacteria"> in tap water is really stringent, which means that as soon as the integrity of the water main is threatened they add <"emergency chloramine dosing">. I'm not a <"tap water...

    Cycling a new tank with the old one still running, anyway to speed it up?

    Hi all, While you don't have any plants you <"can turn the light off">, but carry on changing some water. As soon as you plant the tank the plants will start removing the fixed nitrogen (NH3, NO2 and NO3). Just ignore everything you've read, or been told, about aquarium filters, <"ammonia...

    Spotless water stations

    Hi all, While I was answering @Oldguy's question I found the figures for this: A few people have dipped a conductivity meter into RO water they've got from an LFS etc. and found conductivity readings in the hundreds, presumably because the unit wasn't working and nobody had checked. The lab...

    Hi all, Yes, it works. My suggestion would be to: Take the media out of both filters. Swirl the old filter media into a bucket. Swirl the new filter media in the mulmy water. Put the media back into the filters, putting both new and old media in both filters. Connect the filters back up...

    Spotless water stations

    Hi all, No, they don't, if you actually measure ppm TDS, but I've never had much joy with <"trying to measure TDS">. In practical terms if you have less than 5 microS (~3 ppm TDS) it is DI water. You can also get <"undissolved solids"> as well. cheers Darrel

    Hi all, I think you are right, and that ultrapure water is degassed. I was going to say that would only be the tiny proportion of CO2 that goes into solution as H2CO3 and (then H+ and HCO3-) that would go into solution as ions and that you would measure with a conductivity meter. This is...

    What's the general consensus on a back up heater?

    Hi all, The Ostracods will arrive on their own, they have persistent cysts which blow about in the wind etc. Rainwater and some dead leaves in a bucket should develop a culture, but a small amount of sediment from a pond will definitely get you an inoculum.
