I’ve used this product for three months now and noticed a significant reduction in sludge. My tank feels cleaner and the fish seem more active. No ammonia spikes since I started using it regularly.
Gavin Bower –
It works well for maintaining water balance. I added it during a water change and saw a drop in nitrate levels within a week. Good for new tanks too.
