It's fine to toy around with the ideas in your head...just becareful about listening to the voices in there.
But... the voices... they tell me what to do!
I've used both. I will never use AS again. If you have a full foreground, and aren't looking to keep a sand cap sparkling clean as it will all be covered up by plants anyhow, than MTS is as good as AS, if not better. And with Frank's "Batch II," it can be way better than AS, in terms of growth, health, and color. I got nice results from AS, too, but it is pricey, and if you don't like the dark color, you will have to cap it anyhow.
Cool, thanks for the input. Where can I find Frank's "Batch II" ? Sorry, I've been on like ten different forums over the last few days and am all spun out lol.
Anyway, I'm really leaning towards trying MTS since I've used AS before, and there's just something intriguing about it. However, if I am going to be planting a lot of microsorums, crypts, and bucepalandras for instance, I know the crypts will dig into the MTS well, but will the roots from the java ferns and buces reach? Cause I am planning on attacing the buces to small lava rocks or pieces of driftwood, and I'm not sure yet about the microsorums. What about mosses? They wouldn't have any direct contact with the MTS, but would the MTS still put more nutrients in the water column that the mosses could absorb? Sorry, I'm not really an expert on the chemistry behind all this, that being said, my understanding is that the nutrients from MTS are trapped below the sand and slowly released over a looooooooong time right?
