I now have a 20l tank set up to with top soil, white sand, Iíve followed every step of the guide and included a DIY Co2 system. It's been about a month and the riccia is starting to look good.
However, the GH and KH has increase substantially, it was so high that it fell of my chart from the test kit, could this be happening because I had put in too much dolomite or potassium? The water is also looking a little yellowish and the ammonia level is over 1.5.
I am planning to do a full water change today, any advice on this is appreciated as I am a noob at plant keeping.
