how high\low do you keep your ppm in a 20 gallon tank with 4 apistos? how high\low should my ppm be in a 40 gallon tank with 100 about 1 inch growing fish?
I agree with Mike, I also don't bother about trying to measure pH or dKH, even though I have access to lab. grade kit......For overall hardness, I get a 'good enough' idea by measuring electrical conductivity (µS).
it reads in ppm not tds and it reads µS not ec
