My breeder has like 50 tanks all with soil and bees or tigers etc, I thought I'd double check with him, he says crs prefer kh 2-4, and I would listen to him over you zoidberg. 0kh is just silly, I chimed in cause I'm keeping this species in the afore mentioned tap water, what about you?
Saying in such an indefinite manner the gh is too low to keep either species in our tap water is like saying You can't keep shrimp in RO without remineralising- yeah obviously.
I think your starting to confuse the op with stuff like this.
On a side note I was looking at it yesterday and I wouldn't use seachem gh+ it's all chloride based, including actual salt (sodium chloride)
potassium chloride
calcium chloride
magnesium chloride- ????wtf?
sodium chloride-????wtf?
I don't see how you can't understand that you should buffer the water and remineralise BEFORE adding it to the tank, that way there is no extra bicarbonates so it makes NO difference zoidberg.
If there's the right amount of bicarbonates the fulvic and Humic acids in the aquasoil doesn't need to neautralise them if you want to get technical about it, so yeah in short NO you don't need RO to keep crs with our tap water, TONS of people also keep and breed them in Aquascapes with seiryu etc and high kh. The mironekuton webites pics are literally crs climbing over a mironekuton stone which raises kh, ph and gh so..
My breeder also said "if it works for you do it"
so yeah if it works for you do it, and this works well for him, me and many other breeders.
My babies are cranking along and loving life. Loving their boss aquaria baby powder :)
