Thank you very much for advice.
I don't keep any shrimps in the tank I'm talking about. Only fish species from South America, so they like soft and acidic water.
I'm mineralising my water with Qualdrop plant GH+ at the moment, but would like to switch for something more widely available in the UK. Also been adding a bit of sodium bicarbonate to boost KH.
So at the moment I have GH around 4-5 and KH 1. Ca 20/ Mg 5
Have tried to do my own agent with calcium sulfate, magnesium sulfate and sodium bicarbonate. Maybe it's just me, but I think this make prepared water a bit milky, even a day after 😕
Brightwell aquatics Calcion and Magnesion sounds very interested, maybe I'll give it a try, can you advise what's the best place to buy them online?
Thanks again guys 👍
Ingredients: Purified water, Calcium chloride
Calcium (min) 150,000 ppm
Definitely right. Thousand milligrams in a gram and milligrams/L is the same unit as ppm.That's 150g of Calcium per litre,
Yes, that is right as well. If anyone wants the calculation it is below.That's 150g of Calcium per litre, so for calcium Chloride that's about 819 grams per litre
To be fair to them, the mark up on this isn't as bad as for some other products. I'll say 4kg of CaCl2 is about £10, so £2.50 a kilo and I'll say 819 g is a kilo, and 500 ml of "Calcion" retails for about £16.So the £16 500ml bottle of Brightwell Calcion will cost you around two quid to make yourself based on that Amazon price above.
The same for me.You are best buying your own raw salts - they are so much cheaper than branded remineralisers and utilise the exact same minerals anyway. I get the salts from APC Pure, but there are lots of sellers online if you do a Google search.
For KH adjustment use Potassium Carbonate or Bicarbonate.
For GH adjustment you have a few options, but I use Calcium Chloride and Magnesium Sulphate in a 4:1 ratio, as they are both easy to dissolve.
James Planted tank website has some good info on remineralisation - James' Planted Tank - Re-mineralising RO Water
It sounds like you pretty much have it already sorted. I would just switch to Potassium Bicarbonate though, as adding sodium to a freshwater tank isn't typically recommended, and your plants can use the additional potassium. You can grab it cheaply from Amazon:
As I say, you can use the pre-mixed branded liquids, but all they are doing is buying the same raw salts, and mixing them with water, and charging you for the privilege. if you look at the Brightwell Calcion:
Just grab a bag of Calcium Chloride:
(you can probably get it even cheaper if you shop around).
And make several times the volume of the Brightwell solution for a fraction of the cost. Again from the Brightwell page:
That's 150g of Calcium per litre, so for calcium Chloride that's about 819 grams per litre (if my maths is correct - @dw1305 will correct me if I'm wrong here). So the £16 500ml bottle of Brightwell Calcion will cost you around two quid to make yourself based on that Amazon price above.
I'm probably too late on this one but I think it's important to point out that some so-called RO remineralizers only increase GH and KH. They increase hardness and buffer the water against pH swings. Full remineralizers add a cocktail of additional minerals such as sodium, potassium, fluoride and sulphate. I use Tropic Marin Re-Mineral Tropic, which is a dry salts product.
What about <"Seachem Equilibrium">? I'm not a <"Seachem fan normally">, but it would <"add dGH"> and is designed for planted tanks.I don't have a problem to pay a bit extra for somebody do do right product for me.
I was thinking about seachem, problem is: It's already contains a lot of potassium. To get GH4-5 I need add 16g of agent to 50L of water. Regarding to Nutrient Dosing Calculator it will contain 62 ppm K, right awayHi all,

You would still need to add <"some dKH">. but you could do that via food grade (E501) potassium bicarbonate (KHCO3). I would aim for 2dKH so the potassium addition (K) would be negligible, and K is a macronutrient that the plants need a lot of.
If you select the Bespoke reimin in the IFC calculator Target calculatorI was thinking about seachem, problem is: It's already contains a lot of potassium. To get GH4-5 I need add 16g of agent to 50L of water. Regarding to Nutrient Dosing Calculator it will contain 62 ppm K, right away
To get 2dKH i need add bout 3,5g potassium bicarbonate to this, it's another 27ppm. That's about 90ppm in total, not even mention potassium from KNO3 and KH2PO4
My plan at the moment is: I'll do it from dry salts Ca, Mg, K for plants and will add API stress coat, or something else beneficial for fish.
