Quick update on day 1 of treatment: I did add 3 table spoons of Epsom salt to the aquarium (110G) as per Gabe from Wattley Discus, did not feed this morning (frozen discus mix, blood worms and Sera discus pellets - 1 mil I believe). I did mix 3 oz Sera discus pellets with Epsom salt API general cure and garlic powder (as per the video above) and fed a bit around noon all fish ate including the face down discus - still active except the posture. I am not sure how good is the food mix is... If I have to do it again, I will premix all the powder stuff in little bit of water and add to the food after as the big Epsom grains are hard to dissolve and I am not sure how well it is mixed, same with the general cure, not to mention I saw somewhere the metro is active only for 8 hours after dissolved in water... Regardless, I don't think this is internal parasite issue, but more likely bloat over eating, but we'll see...
