    Cool, I'm liking the power. I'm going for 600mm coping and 50cm fish KH, GH & pH .... what's your target and why?

    Nice looking pond, sits nicely in your garden KH, GH & pH .... what's your target and why?
    As for quality of fish they look alright to me, you do not need to spend a fortune on a koi for it to be pleasing on the eye and get good growth. We all know that's more about your water and their gene pool.

    It's lowish in the water so 85cm+, we're back to square one again.😂
    Let's split the difference and agree on around 80cm.😉

    Cheers, I agree to a point about a good looker doesn't have to cost a fortune but unfortunately most of the koi I like the look of seem to be in the thousands. 😯

    That's because you are looking at mature fish that someone else has already grown. We all know the more mature then your more likely to keep what you see, and obviously you've got a good eyeKH, GH & pH .... what's your target and why?KH, GH & pH .... what's your target and why?

    Steve what size did you buy them at. When you first acquired them. Was they around the 5 to 8 inch size. Sorry about inches old school. Why I am asking is. You must of got a lot of satisfaction watching them grow mate. If you did.

    One or two were around 6" but on average I'd say 8/10" was the norm, historically I found anything less than 8" either Heron bait or extremely susceptible to me killing them with poor pond keeping.
    I consider 10" a good starting point because they're a little bit more hardy, you can see how they're going and they're a bit wiser.
    Two or three of my koi are survivors from a disastrous temporary pond I built when I moved house some 15 years ago it actually became their neglected home for around 5 years, not my most shining moment I have to admit but sometimes life gets in the way, all of those koi are stunted and mutts but that could be their genetics because they came from a crappie dealer.
    Sorry John I seem to have hijacked your thread.

    My opinion is that soft water is a good thing but do we need low KH / pH alongside that?
    I get that a relatively low pH (around 7.0) will minimise NH3 but if that's at the expense of nitrite is it the right thing to do?
    With low KH there's a danger of a pH crash if you don't monitor / manage it. Is that worth the risk?
    I'd say there plenty of evidence out there to "prove" RO is a good thing for fish growth. But why? Because it lowers the GH? Because it lowers the KH? Because it lets you run with a pH around 7? All of the above?
    I'm pretty open minded of what the results are going to be but just over a year ago I turned off my RO to try to balance NH3 and nitrite and never turned it back on. Right now I only used softened water (low GH, relatively high KH and pH) as top up and I think I'm getting similar growth to that which I got when running RO without the risks. I get close to zero GH in my pond whilst the pH is around 8.0. The KH is around 8. NH3 close to zero (calculated from NH4, pH and temperature measurements) as is nitrite.
    What do we think?

    So back on topic
    The way I see it John is, that breeders in Japan grow big koi to a high standard with low PH, GH, KH and TDS.
    Certain dealers in the UK grow big koi at a high standard by mirroring the same water chemistry.
    So common sense tells me I need to do the same in order to achieve my goal of growing big, beautiful koi.
    Personally I have never had issues with nitrite running KH 0.5-1.0 GH 0 and PH 7 TDS sits around 60-90ppm.
    In my experience it comes down to stocking levels and how much water your prepared to chuck down the drain.

    Keith, you can't test to 0.5 accuracy, oops sorry, wrong thread KH, GH & pH .... what's your target and why?
    Had you already got mature media and low nitrite when you started with low KH? I think some people say it's maturing it that's the problem rather than maintaining it.
    I started comparing NH3 to nitrite by using targets of 0.02 and 0.2 respectively, so if NH3 was at 0.01 and nitrite at 0.1 I'd say they were balanced. When using RO I was massively out of balance (zero NH3 and sometimes 0.3 nitrite). Without RO they're a lot more in balance and I like that (I'm not saying it's right, just that it makes my simple mind happy KH, GH & pH .... what's your target and why?)

    Its accurate enough for me John
    I introduced RO within 12 months of filling so I guess the filters were well on their way to maturity.
    Looking back I do recall high levels of nitrite 0.1 but at the time was advised to keep feeding, hide the key to the medication cabinet, sit on my hands and let the filters adjust to the change in PH KH etc.…
    I still see a slight trace of nitrite but this will always be the case when feeding during the growing season.
    My koi are happy, hungry and growing well so I must be doing something right.

    Hungry and growing well I'll give you but how the hell do you know they're happy? KH, GH & pH .... what's your target and why?
    How do you protect yourself from pH crashes? I used to have auto bicarbonate dosing but it always worried me when I worked away that it was a single point of failure.
