Generally a bad idea for many.
But like a non CO2 plant tank, it can be done and requires balancing the
fish load/feedings with dosing the KNO3 etc.
I still think you might consider a nice pH monitor/probe and something to
get a good KH measurement. The KH should not cost much at all. Your GH is
likely fine either way, Ca:Mg ratios of 4:1 seem good but I know it varies
quite a bit in tap waters around the world, but if you do those water
changes...even if it's a bit low, 99% of time there is not a Mg issues. Some
trace mixes sometimes will have it also.
I've had some very large ratio differences with Ca:Mg but mainly excess Ca.
Good to hear about the standards comparing well with the JBL kits.
I think your estimations will still be closer for NO3.
I think about dosing much like a "meal" that will keep the plants "full" for
a couple of days.
You can also get a more accurate reading with the KH by adding 10mls of
sample water and counting the drops(each drop will now equal 0.5 degrees KH
instead of 1).
