I am setting up a black water biotope 50 gal aquarium, and a similar 35 litre quarantine or hospital tank. I ran the 35 litre tank with sand, bogwood, and almond leaves and the ph stabilised at 6.5, with GH at 3o DH. I then added Nutrafin Aqua+ to remove any chloramines, chlorine or heavy metals. However the ph mmediately went up to 7.0, and the GH to 6o DH. Are there any water conditioners I can use which don't affect the ph and hardness. I don't want to do water changes and fight to bring the ph and hardness back down every time.
