I was thinking of the API softener pillow and maybe some peat moss as well in a bag in the filter, also Tetra EasyBalance says it balances KH so if anyone knows or has experience with this it would be much appreciated.
I would rather avoid R/O, especially at the moment but not sure of other options.
This is what API say about the so-called API Water Softener Pillow
API wrote:Rinse pouch under tap water. Place pouch in path of water flow in the aquarium filter. Activity of the pillow lasts 48 hours. After 48 hours, recharging is necessary.
API Water Softener Pillow can be recharged and re-used up to 4 times.
This is what Tetra say about the Tetra EasyBalance
Stabilises important carbonate hardness (KH) and pH water values
Simplifies aquarium maintenance: no need for monthly partial water changes with a moderate fish stock
Extends the period between (partial) water changes
Sustainably reduces phosphate and nitrate
Contains essential vitamins and minerals for healthy fish and plants
Minimises tap water consumption
Suitable for all freshwater aquariums
Ideal for simplifying the maintenance of soft water aquariums, such as those containing discus fish
In my view neither product will really help to soften your very hard water.
The real solution for keeping soft water fish species is mixing tap water with RO water.
Soft water fish species will not do well in the wrong water.
If your tap water is 24.7 dGH (German) then the aim is for something below 12dGH.
The ratio for mixing tap water with RO water would be something like 40:60 (40% tap water with 60% RO water) to give approx 10dGH (lower would be even better).
On a 240L aquarium then that equates to approx 140L of RO water + tap water as a start.
If you do 20% weekly water changes then you will be changing approx 48L per week which would consist of approx 30L of RO water + 18L tap water.
The simplest answer is to keep fish species that are suitable to your water.

The water looks best for Rift Lake cichlids and synos......
Rift lake cichlids (either Lake Malawi or Lake Tanganyika, which can not be mixed, it's one or the other) can be very colourful, I personally have admired these fish in the LFS (local fish stockist).
All the best
