Good to see your still tinkering Dave, and must say everything is looking top notch mate.
Love the Gin Chag, plenty of bling on that Dave.

thanks mate
she was 1 of a group of 5, that were bought in japan in december that were 'first come first served' once finished quarantine.
another lad and I had bought and reserved one.
I got second choice.
there were 2 much lighter coloured ones, one of which went to guy who had first dibs.
and the one i chose had the bigger female frame of the darker coloured ones.
which is exactly what i wanted.
so we both got the fish we wanted in the end
the 3 that were left were snapped up on the spot by other people in the shop....
in pond pics will have to wait until the covers are off.... it's flipping cold out there lol!

I've been running RO water into the pond for the last 2 weeks, and recycle RO since last week.
50/50 with straight dechlorinated water. 600ml/min each.
my PH has been steadily falling started at 7.6 was at 7.4 last week and is now at 7.3
with a KH starting at 5 and is now 3
the TDS was 258 and is now 171
and nitrate is down from 10ppm to 5ppm.
everything looks good, the fish seem very happy.
but i'm doing KH tests every single day.
i'm not taking any chances regardless of what my PH monitor says.
even though it has been running for 2 years now and has been spot on everytime.
i'll see how it goes,
but i'll either slow the recycle RO timer down, up the dechlorinated water in, or dose sodium bicarbonate.
to stablise it at a KH of 3.

And thats fair enough mate
Running RO isnt a simple plug and play thing...
Mike at queni has reported 3 high end ponds in the last couple of months that have had a ph crash and wipeouts due to running RO and relying on readings from blue guardian monitors.
If its done, basics must be observed.
It takes me less than a minute to check my KH with an Api kit when i go into my filterhouse of a morning...

I'd be interested aswell mate am same as you with kh
I thought RO was for the TDS value and that the kh was a by product?

The RO is just to purify and clean the water, it will take out so many bad things and return pure water to the pond.
it also triple concentrates the water thats removed so removes three times more nitrate, than trickle in/out alone.
also things like nitrate, sodium, chloride, copper, chromium, and lead; reduce arsenic, fluoride, radium, sulfate, potassium, nitrate, and phosphate.
a lot of the things in tapwater that carbon doesn't remove very well, or at all.
plus pheromones that koi emit that can restrict growth.
i'm not looking to run a low KH and may buffer it up if needed.
my tap water is usually high in KH at around 8
but recently has been dropping occasionally to nearly 0 for a day, then jumping back up again.
probably a winter water source thing...?
they say softer water helps prevent shimmies and encourages beni,
but i've seen good koi in hard water as well, so who knows...?
Mike Snaden was the main proponent of low TDS,
basing it on the low TDS of mud ponds he tested in japan.
for me it's just an indicator of how much the pond has in the way of contaminants.
as not all TDS is carbonates....
that's where a few people have lost tens of thousands of pounds of koi recently in ph crashes,
relying on blue guardian monitors TDS readings as a reference for KH.
TDS can be any solid dissolved in water including nitrogen wastes like nitrate.
it's simple really, if you run RO you need to regularly manually test water for KH.
i do a test every morning takes 60 seconds as i leave the dropper and vial out ready.
but it won't go from 3 to 0 over night so once you are stable you can skip to once every other day or so.
people who have had a crash probably haven't tested in a week, and then some thing went wrong with automated KH dosing, or the water trickle in KH changed.Last edited by davethefish1; 25-01-2022 at 11:53 AM.
Running heater at low temp?
Covering the pond with polycarb should be enough to stop water temps dipping below 6C for the most...
