There is no governing body of the koi hobby that dictates what equipment people must have, or any definition of what this 'pro' person is you keep referring to
But I think that the starter of this thread wanted to hear from people who actually have experience of manipulating KH in their ponds and how they do it. If it was me I would be listening to the people with years of experience of doing that and not people who seem to want to argue the toss every time the issue comes up.
If somebody with a low KH supply on a budget wants to keep their pond safe, then it is very simple and will cost them approx £20 every 6-12 months for a basic liquid testing kit. They might have to buy a £20 bag of bicarb from eBay every once in a while to keep the KH at over 2.
On the other hand if someone wants to set up a full RO setup with pH control then they tend to PM one of us that has that kit. I've already said above that Darren at Absolute sell the kit. So if interested then phone him. I would recommend DaveJ as one of the most knowledgable in the hobby for RO info.

Pro person in this case is meant as someone who keeps/sells koi as a full time business interest.
Who's arguing? ... I'm just surprised and don't understand the need to PM for detailed info on your low KH setup ... it sounded really interesting from the odd snippets of info
Why not just list what you use, the cost of it and your experience with it good and bad then everybody interested on the forum can benefit and won't be left wondering?
I've got no problem going into detail with any questions anybody asks me.
I have always had to manipulate KH here as I have zero KH from the tap and have already detailed and added links to a simple formula and method that the OP can use ... here it is again for anybody who didn't read page 1 ... https://www.koiforum.uk/water-treatm...tml#post297978

Am not at that stage yet Dave but who knows where this hobbie can take people . Am not happy with my pond as is it with out getting new gear to confuse things . Am interested in every thing koi but just planning on doing every thing but knowledge is a great thing to have . So at some point I may ask for your help first port of call but at the moment am still toying the idea of binning my multibay off for one of the barrel filter that trace knows about
From me and probably many others thanks for the offer of getting in touch for help
Same goes for trace and the offer of helping any one that's what is great about this forum.

What I am currently doing is using pond water recycling RO, which means that I feed 'clean' water from the clean side of my drum through a washable filter and then pump it through a membrane which then sends around 75% to the pond with a TDS of around 6 and absolutely no KH or GH, and sends 25% waste down the drain.
The loss of water from RO waste, and the loss of water from drum cleaning cycles needs replacing in my pond. What I do is set a slow mains trickle-in just using my dechlorinators and a valve at a flow rate that I know from experience keeps the pond level topped up, perhaps a little extra to go down the overflow. My water here is not soft, it. has a variable KH between around 7 and 10 at different times of year, and a high GH which I don't want in my pond.
My setup is fairly. unique to what I wanted and I am certainly not. suggesting you try to copy it. The rate the my trickle in adds KH and GH to the pond is less than the rate the recycling RO gets rid of it, so the pH controller is there to add bicarb to the system automatically if the pH ever drops below 7.2. I've found by trial and error that 7.2 is the sweet spot in my pond. Its low enough that. the toxic form of ammonia is kept at virtually unmeasurable levels even with heavy feeding, but has enough KH to feed the filter bacteria and avoid causing a nitrite problem.
TBH when you set something up like this you have to experiment to find the perfect pH to set, the perfect rate to trickle in etc. etc. Copying someone else pond won't always work in yours.
When I first set up RO and was not using recycling, I didn't have automatic pH control. Nothing bad happened, it just meant that I needed to test KH every couple of days and if it fell to 2 or below I chucked a mug of bicarb in the pond. That's a cheap way of doing it, but you can't take your eye off the ball or leave the pond unattended for days on end. Your pond will never ever have a pH crash if you test your KH often enough. Don't forget that there has to be absolutely no KH left for the pH to start to crash. You will learn the speed your pond uses up KH by simply testing it lots. If you're not able to test more than for example once a week, then. just make sure the KH is at least 4 and you will be fine.2016 new 6000 gallon pond

Running heater at low temp?
Covering the pond with polycarb should be enough to stop water temps dipping below 6C for the most...
