Re: [APD] woes with walsted type tank
>>If the effort was to say that Excel is worthless as an alternate carbon
source, that would be false. I don't believe that anyone here believes
Excel is "injecting CO2", and Seachem certainly does not stake that claim.
But it certainly is a useful carbon source for me for moderate growth
planted tanks which would otherwise be carbon limited and where CO2
injection is either not desired of not effective for any of several
Hey Robert, havn't talked to you in a long time! No, I didn't mean it is not
a alternative source or that it doesn't have merit, (that is another
conversation), but it is not C02, it is not even carbon as I understand it.
It provides chemicals that plants derive from carbon. To say you are running
an injected C02 system using Excel is misleading. Is Excel low tech? It
does not fall under the Walstad method, but I would not call it high tech
either. Providing actual carbon does have a much more dramatic affect on
plants. 20 to 30ppm of C02 will give you a growth rate that Excel will
never match. Fermentation C02 systems will give you better results.
