Hi,

yep i do about 20% every 7 to 14 days. I suspect reading help from
people from another of my messages, that its a combination of;

1. heavy handed feeding
2. not enought plants

Check your tap water. Mine has Nitrates.

You can feed lighter and change more water. But, from what I've seen,
you need a LOT of thriving plants to make a significant impact. And
IMHO aquatic gardening is a hobby in and of itself.
