It won't have done. If there was a rock, that you could add to the tank, that would reduce dKH a lot of people would be very happy.I put some of rock in a bowl for few days and it measures kh 1 so rock defo lowered kh
If you want to raise dKH, just add a bit of tap water.use seachem alkalinity buffer to raise it a little
HelloHi all, It won't have done. If there was a rock, that you could add to the tank, that would reduce dKH a lot of people would be very happy.
Something like a Sphagnum peat or Clay, could reduce dKH <"via ion exchange">, but a rock won't have any CEC.
If it is an inert rock (very likely in Scotland) it won't have any effect on dKH.If you want to raise dKH, just add a bit of tap water.
I did ring AG and he said he had no idea and just increase Co2 .. I thought in past the 123 cultures came in a gel all of these were just liquid I don’t know if that points to a problem but yeah I thought about contacting tropicaRemember that KH measures “temporary” hardness (Seachem alkaline buffer is also “temporary” as is bicarbonate based)
Have you spoken with the AG team re melt?
IME, tIssue culture plants seem to be more prone to inexplicable “melt” than potted plant (there really isn’t much plant material there and it’s usually quite delicate stem/leaf structure that’s easily damaged by poor travel conditions or physical bruising during handling)
If you’re convinced it’s not tank related, I’d email Tropica directly and see what explanations they might offer
I respect your comments as in past you have helped me a lot but haha the rock has decreased the kh as the water was measured before and after the rock was added and it decreased unless there is something on rock that is doing it I did scrub them so I dunno...
That is the great thing about science.Really would like to know which rock, because i can't see that happening either.
Hi all,That is the great thing about science.
All you have to do is ask "is there a chemical mechanism by which the rock could lower carbonate hardness?" as soon as you find out that there isn't one, it tells you that you can discount the rock, so that just leaves the test kit.
Because the test kit measures alkalinity, rather than dKH, you could have a rock which potentially reduces pH, if it contained a lot of <"iron pyrites "Fool's Gold"">.
