When I was doing marine, I stumbled upon the products from Continuum Aquatics and found them to be reliable. Does anyone use their freshwater products for Discus? The ones I am interested are:
1. Discus Elements.T
2. Bio Viv.F - to be mixed with prepared food.
3. Bio Viv.Garlic - to be mixed with prepared food.
4. Flor Viv.Blackwater (optional)

Just FYI, my tank is hardscape with no plants. For planted tank, they even have more products line. The price can be a little bit expensive. Does anyone use them for their Discus and found them to be good?
