Hi Bizarro252, the recommended daily treatment for pure metro is 500mg per 10 gallons after a large daily water change for a 10 to 12 day treatment. You treat for the volume of water in the tank vs the volume of water you replaced. You might be able to calculate how much is in 10 scoops plus factor in the percentage of metro in metroplex.
It does sound like the metroplex is having an effect. I think you should switch to the "good stuff" and continue the treatment for another 5 to 7 days. Still seeing white/clear poop is not unusual. I would also suggest raising the temp to about 88/90 and leave it there until the fish are eating well and pooping dark. The elevated temp would continue even if you stopped the metro treatment after 5 or 7 days. I do think your two threads should be merged so all the info is in one place.
