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
