Turface raising my TDS?

I recently set-up a new tank with plans to be heavily planted. The plants have been in there for a few months and are doing poorly. My other planted tanks are doing fine. A friend stopped-by with his TDS meter and I have a reading of around 530! My water out of the tap is closer to 120. The biggest difference between this tank and the others is that I used Turface as the top 1.5" and MTS (only partially mineralized) as the bottom 1.5". Anyone experienced high TDS from using Turface or heard of that problem?

I'm almost ready to start pulling-out all the turface and using the expensive stuff :-( Real pain in a 6' X 18" tank.

Im not sure if the turface would do that or not, but did you rinse the turface really well prior to using it?

I'm pretty sure I read here somewhere that turface will raise hardness a bit. I would do a search here and see what you can find out.

It is possible that Turface may be contributing, but it is also likely the "partially mineralized" soil is to blame. Dolomite can be a culprit particularly if more than a "dusting" was used. If you used raw clay according to the MTS recipe, this can also be contributing depending on the type of clay being used.

When I spoke to Chris Brown today, he says only a very light dusting on the bottom of the tank of Dolomite is needed for this reason. Even the soil itself may be alkaline depending on what soil was used.
