I've been monitoring my pH for a few weeks, and it goes from 7,9 to 8,2. Yesterday and today the rasboras were spawning again, but I don't think any eggs will hatch. They seem to munch them right away.
I was wondering, if I added demineralised water in a ratio 1,5/20 every week on the regular water changes, would that be a good idea?
SO basically, if I change 20liters per week, and replace it with roughly 18,5liters of tap water and 1,5 liter of DI water, would it soften the water and lower the pH gradually enough to not cause stress?
Could I just keep doing that indefinitely, or should i stop at some point?
The pic is really dark, sorry bout that. Can't get my hands on the other camera.
Does anyone recognise the plant in the left corner, that's got red under the leafs? It came with the wendtii, by accident I presume.
