BLACKWATER

That was the look I was going for having second thoughts about this as so many replies saying ro water I wasn’t going to go down that route more time and expense am not that kind of Fishkeeper I normally just keep fish matches or close enough to my tap water

But in your 2nd post you said you have ec 30 water. If you have ec 30 water why would you need an ro unit ?

Ro water purer than ec30 water that’s the general theme purer the better was it not ?

What is the ec of your tap water ?

Well we learn something new every day according to my test strips round about thirty but I went to the Scottish website more accurate and found out it’s 50 so I think am going to change my test kit

I think you should double check the units of those test stripes; never heard of a test strip measuring ec.

Gh 1-3 if u don’t understand I can convert it any way you want as I notice your in America am in Scotland you do gallons we do litres u do inches we do cm that sort of thing

You are talking about hardness, or GH. anewbie is talking about electrical conductivity (ec) which is not the same thing.

GH measures divalent metal ions - mostly calcium with some magnesium and small amounts of other divalent metal ions.
Ec measures everything dissolved in water which can carry an electrical current and needs a meter to measure it.
The third measurement is TDS (total dissolved solids) which uses a meter to measure everything in water whether it can carry an electrical current or not.

I would describe tds meter a bit different and say it uses electric current in the water to estimate tds. In general most standards have ec as 2x tds but there are other conversion factors.

You can guess tds from kh+gh though i never bothered to figure out how accurate it might be.

In Scotland we don’t do gc we have different water chemistry our water is very predictable

Bud it is ec not gc and locality has nothing to do with it. Please read up on it so you know what you are talking about.

Bear in mind with the stability question - it can depend on where your fish are from. If they're Amazonian, big changes are no problem. If West African, which I keep, less so. Plus playing with stability is a breeder's trick. This morning I had a try with my Hoplisoma (cory) concolor, using a temperature drop as part of a process for breeding. Not for day to day keeping. The OP didn't ask about breeding.

I'm sure the experts @TwoTankAmin has met like his methods. When they've been in my fishroom, some several times, they approved of mine too. They're good people and fun to talk to.

If I get chilled fish, they go right into warm water. I never drip acclimate or any of that. That's a straw man story. But I do aim for stable conditions from water change to water change. Playing the rainy season card is a specialized technique. If someone's just exploring blackwater, they don't need that. It just gets intimidating looking, when it can be simple.

Use your tapwater if it's like what @Dave 007 has. Tint it. Keep blackwater fish. Enjoy.

People and this junk about the stability of parameters.

You know what you are doing, why and how. This sets you apart from a novice who plays around with acids and changes the water chemistry every other water change.

The problem is dave doesn't know what kind of water he has.
