Re: [APD] Rotala macrandra
Let me try again... (The text was snipped based on how i posted).
Good question about R. macrandra. I would be interested to hear about hard
water, high N conditions.

Was always successful. :-) However, adding CO2 to the sand/peat tank
improved success. Adding macros made it harder.

1-2 w/gal. 2 wpg gets better reds, but 1wpg still OK.

have not noticed. range is 70-90 deg F.

always grown pH<7. No experience with higher.

Best luck with KH 1-3. Higher KH tank has higher N, P concentrations and i
have not attempted to figure out optimal combo for R.m.
> > Ca (ppm)-

Ca:Mg ratios in described tanks are ~3:1, typical of softer water. (dont
know my ratio in higer KH/GH Onyx tank)

DK, but can be inferred from TMG use.

Additives are TMG, 10ml/70 gal (1wpg tank); 15ml/70 gal (2wpg tank); both
1x/wk; Only occassional dry macros (N, P). Occcassional supplement of
powdered lime or CaCO3. Otherwise, most of all macros come thru 30-50%
water changes at 1-2x/month. In my experience, too much N made the plant
grow faster and turn greener.
> > Substrate/additives/cables...
Sand plus peat (in 1wpg tank); sand plus soil or Flourite (in 2 wpg tanks).
Never tried cables.
