I did a bit, but nothing that water changes cannot resolve on their own. I do think that the three part is appropriate on larger tanks, especially where half or full water changes are simply not an option. AFR is more than adequate on tanks up to 120L or 30gal. It's probably just fine on tanks up to 55g with a sump, so long as you have a water system that can replace the other minor water elements and rebalance those.
Maybe I can get @Lou Ekus to comment on that. Thank you, Lou for great products!
Just as an FYI, Lou passed away in early October.
