Hi, today I checked my water parameters and I noticed my GH and KH spiked up
GH 80
KH 60
PH 6.5
is it ok for red cherry or it is too much?
nitrates are 0

GH should be between 6-8
KH between 3-4 for stable pH

GH 107-142 ppm
KH 53-71 ppm

Cherries can adapt to a wide range of water parameters
Dwarf Shrimp Water Parameters ? DiscoBee

You say "spiked up"?
Got any rocks in there or using crushed coral/oyster shells?

If it was lower than that, the previous water conditions would have been less desirable than what they are at now. They can adapt, but they do better at the more higher end of their range of water parameters.

I personally would prefer a pH higher than 6.5, like 7 or slightly higher.

yes, I added actually crushed corals to the filter, because my GH/KH was really low, I asked at the petstore for some kind of rock or lava to improve water parameters and they recommended crushed corals, but I think I need to take the corals out for a moment because GH/KH spiked up too quick

GH 80 and KH 60?
Are sure of these values ? °.°

I find that my cherries breed more readily at ph 7.5+

RCS require wet water, thats about it. and it cant be poisoned. any PH KH GH TDS will do, seriously, ANY.

Matuva, the OP is referring to the GH and KH in PPM (Parts Per Million), not drops/dGH, dKH (German degrees) haha.

1 German degree (drop) = 17.9 ppm (or 17.9 mg/L)



OP, if you just have the cherries (Neos) and no soft, acidic water Caridina shrimp (Crystals, etc), then I personally think they should have their GH and KH raised up from where they are. It is fine if you slowly add the crushed coral/increase GH, KH and pH.

Are you using RO water? If using RO, you could also use remineralizers, that way you can better control the KH, GH.
What's your tap water test at? Most people's tap water is suitable for cherries.

OK, does make sense now :wink2:

i never use RO water, usually I use tap water, which is very soft in my area, so I always need to add minerals. i did water exchange today 20 %, I'll check it out tmr
