    never tried Syngonium before - wet feet and all.

    If the goal is to grow Syngonium to reduce the need for water changes ... then one will need to measure the impact.

    Let's pretend conductivity has something to do with the need for a WC ..

    upload_2020-5-21_19-20-3.png

    So only if curve starts dropping would we assume something is improving the water quality in the tank.

    Easy way would be a top-up or WC.

    Or the duckweed takes over, or the house plants start growing like crazy ...


    Lets track what is what over the next few days ..

    So I don’t mind asking potentially stupid questions in the learning process:
    a) is conductivity related to / measured by TDS? Which would include nitrates?
    b) what is the dip between 4h00 and 14h00? Do your lights come on around 4am and start photosynthesis ???

    All good ask away .. will try to explain

    a) so conductivity is the thing that we actually measure - the ability to allow electrons to move from one probe point to the other. Logic the more impure the water is the more chance you going to get current being able to flow. TDS is a standardised way of talking about that conductivity based on specific reference solution.
    P5210899.jpg
    Above is the probe in the water.

    b)The graph is GMT so two hours out. On this tank lights kick in at 6:00 in the morning and go off around 15:00 - so yes direct relationship between photosynthesis and the reduction in the conductivity.

    upload_2020-5-21_21-8-2.png

    Above is my rules of the sonoff that is controlling these lights. You will notice I have extra yes switch the lights off at 22:03 and 02:15 ... that is for when I want to work with lights on at night and have them switched off if I forget to switch it off.

    Cool, thanks @f-fish
    Pretty cool to see on the graph just how responsive it is to photosynthesis. Do you feed in the evening?

    So this little probe is really a nice gadget .. it measure light intensity .. so light ..

    P5210903.jpg

    But my lights are not really above the sensor .. so the lux you see is the beeld from other lights in the room or window or you get the idea.

    I do not have a fixed feeding plan for my tanks ... but typically fish get some grinds in the morning and maybe a sinking pellet or two, three ... and a few more pellets at night is more the exception than the rule.

    I’ve always wondered exactly how fast food gets processed through the fish gut, excreted and creates a rise in nitrates. Sure it depends on species and food but have you picked this up in your graphs at all?

    hmm

    Lets experiment ... was messing with some network stuff this morning - so the days graphs might look a little funny. Perfect opportunity to up the sampling rate and do a lights out test for a few hours.

    Let me set that up.

    So ambient light .. since we did not switch the lights on today.

    upload_2020-5-22_18-5-3.png
    Fixed the time issue everything from around 8:30 is now showing as SA time.

    Over feed at 12:00 P5220905.jpg 5g


    Going to run the lights for a few hours tonight - see what that does to the numbers.

    Yes! This is going to be interesting, can’t wait for results :thumbup:

    You’ve got some great toys to play with!

    Ha ha .. must be the silicone cup you are talking about ;-)

    Decided against the lights ... rather see what the tank does in the dark state during the night .. also changed the sampling to every hour.
    upload_2020-5-22_20-53-39.png

    The probe uses BLE - but every time you tell it to probe the battery drains just a little more.

    Will look at the numbers in the morning.

    Added some HC to the tank .. no CO2 .. low light so it really should not do well.

    Part of it was to see if I planted it well enough - since the bulldozers uproot everything in this tank. So I dropped some sinking pellets in the are where they are planted.

    This answered one of my questions I have been pondering over the last few days - how do sinking pellets that I drop on the one side of the tank end-up on the other side - I have a feeding corner that I mostly use to keep the bulldozers away from the rest of the floor.
    P5241005.jpg P5241009.jpg

    Yes these guys literally pickpocket a pellet and the run with it.



    P5241013.jpg P5241016.jpg

    HC planted - pellets dropped, lets see what survives.

    Random shot - no story ;-)

    upload_2020-5-24_15-2-6.png

    Did a small WC to remove some duckweed and get the TDS below 300 for the week.

    Nice drop in conductivity as expected.

    I’ve seen my amanos do the same thing with sinking wafers, pretty incredible.

    Was there a noticeable spike from the 5g?

    No not really, but I also have a BCB filter in this tank, so I would assume it will cope with NH4 if it is working as advertised.
