If you use new rac soil, you should not have so much problems.
Using aged tap water is good compared to straight from the tap but you might want to try distilled water from ntuc with all reading 0. If you continue using aged water from tap, I am afraid if you ever succeed, you might have mastered the art of controlling water parameters as I am not sure whether the water supply is consistently maintained at a set parameter. So why leave to chance when you already know distilled water is all 0.
There are liquid adds to help you increase tds, controlling it (Gh) will be your challenge. Get the tds up from a shop that uses the product they sell so that you know you got the right product, if the shop doesn't know how each product affects the gh, run away.
Getting rac soil might be your lucky break, don't mix it with BW substrate.
