I've been most happy with Prodibio as it's cost effective and doesn't require as much dosing as the others, yet IME has been just as effective as the others. Brightwell is newer and I've never tried it, but all in all they're all nearly identical in components. I will say that the "newer" ZEOvit supplements are much weaker than the original (when they came to US) bacteria and carbon sources. They're more diluted, which = you must use more, which = they make more $ (and you spend more  ). With Prodibio I dose one vial of bacteria every other week after my water change (which I do weekly), and one vial of carbon source every week. No other additions or dosing of anything. |
