It's a 5g tank since that's as large as they'll let me have. My 60p at home has been relegated to extremely low light/no ferts anubias duty.
Is there a problem with using these methods to dose a small tank? I have access to some fine balances so I can make liquid concoctions rather easily (which was what I did at home). Weekly 10-20% are fine for me..it just becomes a problem with 50%. Dumping out 2g of water every week on top of my frequent top offs draws a lot of unwatnted attention.
