It's going to keep raising the gH and kH. My 10-gallon goes up on average 2 points between weekly 40% water changes with straight RO water.
How long has it been set up? I’ve read that the effect may lessen a good bit over time. I wonder if putting some shallow bags of aquasoil under it would help (and how long).

That is quite annoying. A substrate that's not aquasoil really should be inert. I am glad I decided not to get these substrate for my cories. I really had liked the color but the cost was too prohibitive.
 
Well, my fault because I assumed all sand except aragonite was naturally inert. When the bags came in, they did say “may raise water hardness”, but I assumed it would be minimal. When I tested yesterday, my kH was 9, gH 12. My tap water is usually kH 0-1, occasionally 2, and gH is 3-4. I did remineralize my tap water as usual before filling the tank, but I don’t add anything for kH in these tanks.

Today I did a 90% water change with straight tap water. I also cleaned the glass and set 1/2 bag of Landen aquasoil in mesh bags on top of the sand. That’s just something I had in the closet. If I find that levels are decent after a week, I might go to the trouble of putting shallow bags of aquasoil under the sand. It’ll also help keep the tank cycled while I’m experimenting, because I don’t want to add livestock until everything is settled. Meanwhile, I put the tonina in the first tank. I “think” all of the other plants can deal with it. I just don’t want to give up on this sand after just buying 5 bags of it (I used 4). Oh, and I’ll test in a couple of days. There’s also the RODI option, but I wonder if that would just make the swing greater.

Well, I need to get to work on the other tanks now. 😄
 
I haven’t gotten around to switching my canisters over yet. Have you noticed any increase in flow @Kwyet? or any other improvement?
My main concern was gurgling and air-locking, and so far that hasn’t occurred. I haven’t noticed any increase in flow, but I don’t have any objective data either.
