Title: Sensors
Post by: STEMO on 22 July 2018, 18:31:56
Not in your omega, in my white goods. (Yes...white goods, Tigger)
The sensor in my washing machine weighs the clothes and alters the washing time. OK.
The sensor in my tumble drier knows how damp my clothes are. Nimps.
The sensor in my dishwasher knows how dirty my dishes are and, if I put it on AUTO, it adjusts the washing time. It works too. Now how the f**k does a sensor measure how dirty your dishes are?

TDS
total dissolved solids sensor
or is this question just for Bazza ?  :P

No, I keep koi carp and use a TDS meter to monitor water quality
along with ph meter and many chemical tests because Koi are very fussy about the quality of water they drink ,
then they pee n sh*t in it ,so water is recirculated via self-cleaning drum filter, biological filter aqueduct, to purify it

My dishwasher is not allowed to leave the kitchen till all the pots are clean , that's how mine works  :y

Maybe you can tell me how to stop the water in my pond (big goldfish looking things in it - we inherited them with the house) turning green and growing (depending on how it's feeling that day) green stringy algae or green cloudy algae...

A very common problem with ponds because you can't use chlorine like you would in a swimming pool,
your pond probably has high levels of nitrate in the water,
fish eat food and produce ammonia, with a good filtration system, ammonia gets converted into nitrite and then nitrate, nitrate is plant food, most ponds are in direct sunlight all the time (except night obviously)
So , water, plant food and lots of sunlight are ideal growing conditions for algae, turning water green or forming string algae.
you can buy treatments that are formulated to stop the algae, some more effective than others
OR , you can do what I and most serious koi keepers do .
1: provide shade, pergola, sun sail, etc, not always practical
2: reduce nitrate
3: use UV c light to kill algae (you can buy UVc pond filters to pump water through, splitting the algae cells , which clump together and are caught by mechanical filters )
4: try and reduce the amount of food and fish waste, the most common problem,overfeeding fish .overstocking of fish.


I have built my own, self-cleaning rotary drum filter, which removes most of the fish poop, waste food, decaying plant matter.(some filters use sponges but they clog and need constant cleaning)
after the RDF, water goes through a biological filter which contains media that is home to good bacteria, they convert ammonia to nitrate, which converts to nitrite (plant food)
I have plants (lilies and very fast growing mint plants)  that use up nitrates.
i also do a regular 10% water change with fresh water (which is run through an activated carbon water filter to remove impurities and treated with dechlorinator (chlorine is harmful and burns fish)

I monitor water quality very closely for ammonia, nitrate, nitrite, chlorine, carbon hardness, ph, parasites etc and TOTAL DISSOLVED SOLIDS with a TDS meter. uses a light source and measures particles in water (dishwasher sensor technology)  :P

so, having a few fish in a pond is more complicated than people think

If you just have a few small fish in a pond, an off the shelf pond filter with built in uv lamp ,a decent pump etc and reduced feeding,  >:( should cope to keep water clear.

If you have big fat 2' long plus Koi that eat prawns, chicken strips, peas, rice, muscles etc on top of vast quantities of food pellets, you will probably need serious filtration equipment  ;D

Man alive, that all sounds complicated and expensive.. and L already wants to get rid of them to replace it with a hot tub, if I have to spend any more money on it she'll probably just let the cats eat the fish ;D

We already have a big filter with a UV lamp in it, but that seems to do the square root of sod all.. we can try feeding them less - no idea how much of the pellet crap they're actually meant to eat, mind ;D

Sell the fish, fill it in or make a sand pit for kids/grandkids, job jobbed. :y

just put in what they will eat straight away within 5  minutes  :y

the UVc lamp (bulb) requires replacement once a year and cleaning on a regular basis to work
that's if it is big enough to cope with the size of pond

be warned, hot tubs require constant monitoring of ph, chlorine, alkalinity, TDS levels etc etc  ;D
what about astro turf ?
or a nice slabbed patio  :y

Think bath water,  skin, hair, cheese etc  ;D

plus hot tubs require heating and pumped water ,new filter cartridges etc
expensive unless used all the time
cheaper to have a dunk in the village pond  :y

Problem is, the "dissolved solids" in our village pond are now extra concentrated due to evaporation. :-\

Sorry Doc  :-[
I see now,"top up and report back" would be  sticking a plaster on, rather than solving the problem once and for all
clearly, I should have looked at the bigger picture  :-[
