Re: Slow deformed growth, and brittle plants....
Aquaman just curious with around 45 ppm of calcium in my water why do you think that this is the nutrient that is missing in my tank? Im not trying to say your wrong.... I just dont understand why you think that.... how much is enough then if 45 ppm isnt? Also you said...
In earlier post i NEVER said that I used this as a Flourite substitute.... rather explained it in PHYSICAL chara. SIMILAR to flourite. and as far as it being defficient in Ca... it was my understanding that in aquatics, Plants generally perfer not to have a high concentration of Ca in the substrate?
I dont really know... I do appriciate your insight... how ever I dont really see how this directly has any affect on why the plants are not doing so well.... other than if you think that the nutrients have precipitated into the substrate and raised to toxic levels there. However even so.... seems as though the levels of nutrients I am adding just arnt high enough anywhere substrate or not... to cause problems? as Tom as listed many times doing expierments with different nutrients at high concentrations.... much high than in my tank with no ill effects.
Back to this.... I still really dont understand why we know that Ca is in short supply.... I just dont see it? maybe you could explain that one better to me and others.....
thanks for the input

Schultz aquatic plant medium is mostly an illite clay which is very good for
storing cations which the mineral picks up from its environment in small quantities. The use as a substrate is more appropriate outdoors where you have external inputs such as wind blown dust and organic matter. This substrate is probably defficient in Ca unless it was calcined in the manufacturing process. It is definitely nowhere equivalent to Flourite in iron content. For a flourite substitute, Turface Pro is probably a better choice for both iron and calcium.

Since we now know that Ca was the nutrient in short supply
Back to this.... I still really dont understand why we know that Ca is in short supply.... I just dont see it? maybe you could explain that one better to me and others.....
