Seneye

Does anyone on here use a Seneye?

I was gifted the basic one a few years ago, but it was one of the things that fell by the wayside when my tank was neglected.

Along with everything else, I'm now trying to get it going again and noticed that things have moved on quite a bit. I'm wondering whether all / any of the available upgrades are worth it. (Looking at the shop, it seems it could be a bit of a money sink)

I wondered what other people think of it.

Id normally say money sink... depends how 'into' computers/data you are. 

But... you've had the main capital outlay done for you so really it's a case of what can it do which your using your test kit for currently and what extras does it provide and how useful are they.  For example i think one of this thinga it monitors is water level... how likely is this going to be a problem I'm most tanks... they are either full of water or the waters all over the floor.  Evaporation isnt a problem inbetween weekly water changes.

If you continue this thought process with the other parameters... you'll find your answer!!

I knew I had seen comments about Seneye on here before - you'll find them if you do a quick search - but this review might be the most helpful one: https://forums.thinkfish.co.uk/tank-equipment-reviews/review-of-seneye-home/msg20383/#msg20383

I'm afraid I have no experience of it whatsoever.

Thank you fcfm for the link. I did do a search before posting. I now don't know what I actually did because I didn't find that review.

So I got some more slides and have set up my Seneye again. Now I've got a couple days data, in trying to work out what it is telling me!

Could you post some screenshots??

Happy to help understand the data... also kinda interested in seeing it in action anyway!

Hi @Matt

I decided that my queries were more related to water chemistry, so posted here

https://forums.thinkfish.co.uk/general-fishkeeping-advice/water-chemistry-according-to-my-seneye/msg36127/#msg36127

Screen shots are a bit beyond me at the moment, as i'm on think fish on my phone and the Seneye software is on my laptop.

Here is a photo of my tank parameters within the Seneye 'dashboard'. The 4 graphs on the left are all for the last 3 days. I've had to crop the picture quite heavily to make it small enough to upload. So the top three graphs are: temperature, pH and Free Ammonia (ppm)h

The craziness is because I've been reducing the level of my substrate, and so have ended up doing 2 X 100l water changes over the weekend. I decided that this kind of drastic water change should be ok, because my previous water changes didn't show up, so my tank water must be close to my tap water. And although the Seneye doesn't give a hardness measure, my tap water is described by my supplier as very soft.

What I find interesting is that the ammonium has gone up significantly, after the addition of new water.

@Sue, you said elsewhere that nitrate is a plant's second choice nitrogen source. Is it ammonia or ammonium that is the first choice? I can see that the ammonium seems to inversely track the pH, and I know I've read that the pH affects the ammonia: ammonium ratio. Annoyingly, I can't change the scale of the X axis, so can't see the trend for ammonia.

Could the pH changes have anything to do with the amount of CO2 in the water? Because it doesn't really seem to relate to when I added new water. The lowest dip was 6am - 8am today.

I can't actually remember whether plants take up ammonia or ammonium  :-[ but it doesn't really matter. Because ammonia and ammonium are in an equilibrium (pH and temp determining how much is in which form), if the plants use one of them, the equilibrium restores the balance. It's the same for the filter bacteria which only use ammonia.
[Think of it like old fashioned balance scales with a pan on each side. Add some beads to each pan so that the pans are equally balanced. Then take a few beads out of the left pan. To keep the pans level some beads have to be moved over from the right pan. Then take some more from the left, and more have to be moved over from the right pan. And with the ammonia/ammonium analogy, beads are also being added to each pan as the fish excrete ammonia so the pans are never completely emptied]



pH does vary with the time of day, particularly when there are plants in the tank.
Animals and plants respire. They take in oxygen and they release carbon dioxide. They do this 24/7.
Plants photosynthesise. They take in carbon dioxide and release oxygen. But they only do this when it is light.

The net effect is that during the day the plants take in more carbon dioxide that is being released by the animals and plants, but at night more carbon dioxide is released than is taken in by the plants. There is more carbon dioxide in the water at night. Carbon dioxide dissolves in water to make carbonic acid. Therefore the water is more acidic at night and the pH is lower at night. The amount of carbon dioxide will build up during darkness so the pH will be lowest just before it gets light. As soon as it gets light (daylight or tank lights) the plants start photosynthesising, take up all the accumulated carbon dioxide and the pH rises.

@Helen Unrelated to the Seneye but if it helps, press and hold Ctrl then hit Print screen and you have a screen grab. Hold Alt at the same time and you grab just the active program window. You can paste it into another program with a Ctrl v
Happy grabbing :)

Ha ha. Thanks @Andy The Minion . My issue is more about which device has which information. My Seneye page is best viewed on my laptop, but I access this forum from my phone. I contemplated emailing a screenshot, but was too lazy and decided that just taking a photo would be easier.  :-[

@Andy The Minion  you'll be pleased to see that I've managed to coordinate my devices.

For those that are interested, here is a snapshot of my pH over about a week (might be 5 days).

Slightly out of context of where this conversation has gone, but this a comment about how I think the Seneye works, from another conversation.

There is the ability to 'trim' the Seneye readings, but I don't know about calibrating. I don't know how I would start doing that. But, the slides only last about 30 days and then need replacing. It is the slides that contain the pH and ammonia tests. From what I can see (without destructive investigation!) the ammonia and pH are like test strips with an optical reader.
