AlexCro said:I have just received a glass drop checker (like a Boyu but from eBay) and as there isn't any instructions I need to know what colour it should be for good Co2, Green, Blue or Yellow?
but if you have no fish or invertibrates go for yellow so you no for shure there is no deficiency of co2.Flyfisherman said:Blue No Co2 in water column
Green is good
Lime Green is even better
Yellow - Dangerous too much Co2 in water column.
Hi Cro,Cro said:I know using 4dkh solution is better than RO water but the missus is moaning about spending at present so it has to be RO for now.

I have, it states "The accepted practice is to fill the drop checker with distilled /deionized/RO water that has been adjusted to a known kH value" So my assumption (which I can see now was incorrect) was that all RO water was adjusted to the same known value. The RO water I have now is approx 20KHceg4048 said:Using RO water is worse than pointless. Please read the article I gave the link to.
No, just RO water.ceg4048 said:Have you washed the dropchecker with anything acidic, like vinegar for example?
I've used 2 different reagents and they both come out the same.ceg4048 said:Test the pH of some other water like your tank water or tap water using the same indicator reagent. It could be duff.
Was trying that, but a box full of chemicals (going EI soon) and another box containing 2 power heads dropped through the door today.chris1004 said:Do what I do mate and don't tell her.
I'll have to have a bash at that, thanks.chris1004 said:Seriously though if your a bit stuck you can make your own 4kh solution if you have a kh test kit, RO or di-ionised water and some bicarbonate of soda.
As a quick fix until you can obtain you 4dkh solution - what ever solution you used in your JBL drop checker put it in your glass drop checker - problem solved.Cro said:My old JBL drop checker always showed the correct colour
It was tank water, as per the instructions in the JBL box.Flyfisherman said:
