Helepolis Posted November 19, 2017 Report Share Posted November 19, 2017 My recently set up 10g ph is 7, wanting it around 5.5. My kh is 0, using sl aqua soil, salty shrimp gh, cholla wood, Adler cones, almond leaf, Ro/di water that test around 6. Can't figure out what's pushing it up to 7, recently changed 50% of water.

chappy6107 Posted November 19, 2017 Report Share Posted November 19, 2017 do you have any rocks in the aquarium? Quote Link to comment Share on other sites More sharing options...
Helepolis Posted November 19, 2017 Author Report Share Posted November 19, 2017 It's been running about a week, using filter media from another shrimp tank. No rocks in the aquarium. Quote Link to comment Share on other sites More sharing options...
bobthesushiguy Posted November 20, 2017 Report Share Posted November 20, 2017 hmm, I have heard some soils being unable to actually lower ph to 5.5 and gets stuck at 7.0. people say it is like one bag out of a few that makes this kind of issue occur. However, there can be other factors, but I still dont know why if u are doing ro. It might be that u are adding too much gh+? are u measing ur gh?

Helepolis Posted November 20, 2017 Author Report Share Posted November 20, 2017 (edited) I haven't checked my gh, kinda assumed it would be around 5-6 but ill check tonight. Thanks. I have 2-2 1/2 inches of soil, maybe I will try to contact so aqua and see if they have any advice.
