[APD] comparison of PMDD and Toms method side by side please
Hi all,
Could someone explain in newbie terms what is the main dif between PMDD and
Toms formula, near as I can tell Toms supplements phosphates also where as
the pmdd limits them. I am admittedly a confused planted tank newbie. Sort
of a side by side compare/contrast.
I would like someone to sum up a list of chemicals used so I can
order/locate them. I'll worry about the dosing when I get them. (feel free
to correct any errors/omissions)
I understand that as a newbie I should pick one plan and work with it till I
figure out more, I just need to understand the contrasts/similarities
between the methods so I can order the ingredients, _THEN_ I'll bug you
about how much to use for my specific tank requirements :)
PMDD uses:
K2S04 (potassium sulfate)
KNO3 (potassium nitrate) Greenlight's "Stump Away" is pure KNO3??
MgSO4+7H2O (epsom salt)
H3BO3 (Boric Acid)(if your trace does not contain it)
Plantex CSM or Microplex trace mix
Toms method uses:
K2SO4
KNO3
KH2PO4 (can use Fleet enema) for the phosphates
Mg/Ca, fine ground dolomite in the filter
traces (Tropica master grow, SeaChem Flourish etc)
I assume CSM would work here too? If I still use CSM would I need to add
anything that would be in the MG and not in the CSM? Is that all that is
used in this method? (omits MgSO4+7H2O and H3BO3 that are used in PMDD are
they in MG and that is why they are not added?)
Please someone outline the two fert plans side by side dragging it out of
the archives leaves me a LOT of room for error.
I understand this is assumed to be a "high light C02 enriched" formula and
assumes a 50% weekly water change, and that it also assumes a flourite type
substrate supplement. (other than plain gravel)
I'm not sure mine fits in there exactly and I will get around to posting my
exact systems details including fish load substrate etc. At this point I am
mostly trying to understand the differences and common things between PMDD
and Toms method.
Thanks
Candy
