ok....no more Cycle, those bastards...well, I added that occasionally with water changes.
How important is it to add kalkwasser? Kalkwasser controls alkalinity, PH, and other ions in the aquarium. Do you just get the powder and mix a batch every week, or is there a solution that you can buy?
What about phytoplankton, strontium, iodine, and trace elements?
Is there any solutions that cover most of the bases?
