Don't Brita filters reduce limescale?
Looking for advice on the different filtration options out there without going all out, plumbed in, RO or anything like that.
I'm currently using a cheap Britta water filter jug, but I'm pretty sure it's doing nothing at all....
It's probably the total water hardness that I would think the most important thing to eliminate?
My last HX machine l used to use Mt Franklin bottled water but the wife didn't like all the bottles and the constant cost.
Impossible to advise you without any data on your water. Have it professionally tested and then come back to your thread.
Your current setup will remove dirt and algal spores from it and that's about it. Brita jugs have negligible to zero effect when it comes to softening water.
I can definitely recommend a chat to the team at Bombora, but first if you want to get serious you should get your tap water tested. Once you have it tested you can see what you need reduce- is it TDS hardness etc.
Personally I have a bench top filter system which is good because I am renting so I don't need to do any kitchen mods and can take it with me. It also makes drinking water far more palatable and I change the filter cartridge every 6 ish months. Cost about $120 from memory and spare cartridges about $40.
If your machine has a tank (not plumbed in) then you can buy those small water softener filters that attach to the end of the water intake tubing. They last a couple of months before you have to “recharge” them by a process involving soaking them in salty water and heating(?). I’ve got 4 that I rotate every 2 months before I recharge the lot in one go. Most online coffee places sell them. They are probably not as effective as RO and other expensive systems but they do soften the water to some degree. I also use a standard water filter system to remove chlorine.
Nope- you don't rely on an inline filter to do appreciably more than a Brita...
Unfortunately this means it is very hard to measure when the resin is exhausted: the easiest and cheapest way is complexometric titration against EDTA using Eriochrome black as indicator. The test is easier than it sounds.

Try one with 200ppm hardness (or more) which is not uncommon in parts of Australia
In that situation it will exhaust more quickly. A back of the envelope calculation suggests that their stated capacity of 100 litres per recharge is pretty conservative, even with 200 ppm water. Assuming you are quoting hardness as CaCO3, 200 ppm = 2 μM = 4 μEq so their 100 litres is 400 microequivalents. Even the tiny quantity of resin they put in these things will handle that (most resins have a capacity around 1 eq per litre resin).

From the Brita website
MAXTRA+ MicroFlow Technology reduces:
metals such as lead and copper
chlorine and other substances that affect water’s taste"

I’ve got a similar machine at home
I reckon just get a bench top water filter like this

It’s good coz you can use it for your drinking water as well as for your machine

One pool shop says l have 90pps calcium hardness.
Going to try one other shop
@Adam76, if your pool shop test is cheap enough you could ask them to do the hardness test on samples of your water pre and post filtration. That would give you some actual data on which to base your decision.

Thanks, so I'm looking to see what sort of filtration system would be best for my set up and what other people are using?
I went through this exercise when I found the local water in Perth was going to destroy the stainless steel boiler in my ECM Mechanika V Slim.
Our water is extremely high in Chlorides which the normal goto inline filter the Brita C150 Finest does not remove.
My solution is to use Pureau water which I buy in 10 litre goon bags for around $8. from Coles, Woolworths etc...
To that I add the mixture as described in here
Looks and sounds a bit complex but its not. All you need is a set of digi scales and I use a 5ml syringe, some Epsom Salts and Sodium BiCarbonate both of which are available from your supermarket shelves.
I mix up 2 litres at a time. I've also experimented with taste while getting a desired pH and TDS, and have reduced the individual component amounts into the Pureau to 4.2 ml per litre rather than 5ml. This gives me a slightly alkaline water and lower TDS than using 5ml. The taste is somehow cleaner and a little sweeter to my mouth anyway.
TDS between 70 and 80
I also bought a TDS meter and an electronic pH meter. But these are optional, I'm just a bit anal.
The other solution is to buy a Reverse Osmosis unit for about $250, to which you would still need to add the recipe as above.
I opted not to go this path as RO has a high waste level (1 litre of waste water to 1.25 litres of pure water), and the waste water from the RO is full of the nasties in the water in a concentrated form.
Water hardness and limescale build-up is a favourite topic here - we supposedly have soft water but I still see plenty of limescale around our taps. I didn't want a plumbed in water-supply and there are no lines near my machine, so it would have been expensive anyway.
I opted for this highly technical mix of mixed-bed resin, recycled Sunbeam softener cartridges, an old yogurt container and food grade plastic tubing: https://coffeesnobs.com.au/general-c...tml#post612949
Two years on and I replace the resin container each month and in my daughter's Sunbeam less often - I still have the original shipment.
I bought some Hach test strips with a hardness indicator (you can get them from Bunnings in the pool section - but about $50). Hach do sell water hardness only test strips, but you need to find a stockist because transport kills. Woolies actually sell pool test strips that include hardness indicators... $20 or $15 on special last week! These might not give you a precise read, but it will be close enough. (edit: Just checked - a number of sponsors including JetBlack sell test strips)
With fresh resin installed, my test strip shows as low as it gets and my TDS meter is 4ppm.
After two years I just pulled my mushroom apart on the ECM and while there are a few deposits of scale, I thought it was pretty good for my yogurt container filter.
