I use a PH controller that doses bicarb when the PH falls below 7.00
If I am away during the growing season I set a safe mix of RO/mains water to maintain a safe KH/PH.

I think you have the same pH controller John has (that he isn't using any more). It's the one I was going to get.
Do you mind me asking which probe you are using with it?
I need to get one very soon and not sure I can justify getting the £420 one Mike is selling, especially as it is my daughter's birthday this month and I am currently trying to re-landscape the whole garden on a budget2016 new 6000 gallon pond

great controller lara running one myself theres two set points on them my first sp1 controls dosing pump and the second sp2 controls a 240v solanoid valve with mains water feed hence dosing pump failure mains water will do the dosing

KH, GH & pH .... what's your target and why?
Not speaking for John, but we both use a water softener on our incoming mains water ( I know that from all Johns posts on the subject!)
The water softener works by removing the magnesium and calcium present in your water supply through a process of ion exchange.
I have only recently installed one, not for the fish, more for my daughter who struggles a little with psoriasis - I have seen no negative impact on my fish or in fact my water parameters, not that I was expecting anything anyway (e.g. it wouldn’t improve your TDS; mine runs around 230-260 and has remained the same since running the softener).

There are a few companies in the U.K., but I couldn’t help you out in Thailand.
My source water (South East) is likewise from boreholes and pretty hard, although I understand various water companies are now experimenting with water softening on a larger scale given the health benefits.
Harvey are one of the bigger suppliers/installers in the U.K.

If you can get hold of a unit, actually installing it isn’t massively complicated and having seen what the Plumber did.
Block salt is used to clean the softener unit periodically; you insert two large blocks into the unit basically.
(You don’t get loads of salt dumped into your pond either, before someone asks!)

Rob is spot on with what I do.
I started doing it to help the RO I was running at the time but since then I’ve turned off the RO, only use the softener and am very happy with the results.
Any second now some people who haven’t tried a softener will be along to tell you what a bad idea it is

If I managed to get one, it would be a different make ( I’ve seen something for swimming pools ) but what’s the best way to use it , I was. Thinking a separate feed to pond , would I just trickle it in 24/7 ?

I trickle in 24/7 with softened water. I’d say that’s the best option.
Ideally you want a twin cylinder model (I use a Harvey’s) so one cylinder is regenerating whilst the other is in use otherwise for a couple of hours at a time you’re putting unsoftened water in.
Check softener capacity vs what you think you’ll need. If I feed 1lpm I’m at the upper end of what a domestic unit can supply and I can use 25kgs per week of salt to do it.
We soften all the water coming into the house, it makes no difference to the pond but we prefer soft water.

I,v been looking around today at units , but it’s like talking to idiots in Chinese . I can speak a lot of Thai but when it gets technical it’s difficult,and my wife’s (Thai) away . But they do not sell any water softeners that use salt they use resin , how much they produce and at what level they have no idea ,how often I would have to change resin etc etc not a clue . So stuck for now , I,m going to talk to Thai koikeepers and see if anybody softens their water and what they use , but thank you I,m going to post a separate thread on my kh and gh maybe you could take a look and offer some advice . Regards john

They generally have resin inside but use salt to regenerate the resin.
The resin normally lasts a few years.

Not many agree but I think low GH and high KH is about as good as it gets for the following reasons:
Maximise growth through low GH.
No danger of a pH crash because of high KH. So no need for bicarbonate dosage.
Less time to mature media because of high KH.
Nitrite and ammonia toxicity levels are more aligned. Low KH tends to push ammonia down but increase nitrite leading to an imbalance where ammonia is near zero (good) but nitrite often over acceptable levels.

When I mentioned salt they had no idea what I was talking about , so I could buy a cartridge put resin in it connect it to my pond tap and turn it on ?? Then what , all these people want to do is sell you something then it’s up to you if it’s the wrong size or doesn’t do the job they don’t care

Ok thanks just posted about my gh and kh perhaps you could take a look and tell what all means

They have one unit that takes a resin cartridge but it’s small , like you,d fit under a sink and they do a lager model but how would I know when the cartridge needed changing ? It’s not east out here lol
