Re: R O Right or ??
Barry, I didn't understand the relationship of silicates to buffering. It
sounds as though your water isn't buffered at all, if you have such a high
pH, but I didn't think silica caused that. Do you have silicate hydroxides in
the water? That is pretty strange. I also have well water, and it too is so
high in silicates that I can't keep a reef tank due to the overgrowth of
diatoms on everything. If you're getting good plant growth now, it's either
the buffering that brought down your pH or iron in the additive, I suspect. I
could ask if there's a cheaper alternative than the additive, but whatever
works is the point. I sometimes get my ears perked up when people talk about
commercial brand names without respect to what is in them and in what way
they rationally solve a problem. I hadn't kept up with this thread, so I
guess I'm playing catch-up. - Bob
