The truth is we can go back and forth for 50 more pages debating every little thing about the RM method and if it is "good enough" or a "waste of money" or if it is "too mad scientist" or whatever other excuses are out there.
None of that is even relevant for those of us THAT ACTUALLY USE the RM method. Find me all the negative comments and people that had such poor results they quit using the method....I will wait...
I started running the RM method in February of 2021. I had done a 10% water change a couple days before sending my first ICP. I did another 10% water change in May for no other reason than "that is what I am supposed to do" and it was pointless. It wasn't addressing any issues. Water changes don't replenish trace elements. This is fact. The salt mix would have to contain elevated parameters of each trace element. None of them do.
And guess what? That holy grail almighty TM salt is having serious issues right now. I know many want to sweep it under the rug but the issues aren't going away. They are very real and here to stay. We are seeing them pop up daily right now in the AskBRS group. They are becoming so prevalent I am going to find out if my new box is from Turkey. If so, it will go directly in the trash. TM needs to pull ALL salt from their Turkey factory until they figure out what has happened.
So, for those of you relying on water changes as insurance or to fix problems, you sure put a lot of trust into these salt companies. We have to assume they don't ever get anything contaminated and just trust them. Kind of like those of us running the RM method trust Andre and his findings. So far, my results are lining up directly with what I expected. Best tank I have ever had in 17 years. Dosing a few dailies is so much easier than a 20g water change. Not to mention I live in Utah and we are under a very real threat of drought. Dumping thousands of gallons of water down the drain every year is not responsible in the least.
I send off an ICP test every 2 months now. Salt costs more than that even for IO Purple. Andre's additives are actually super cheap compared to others. $20 for 500ml is 1/5 the cost of ATI and Triton. Andre will even tell you the concentration. Triton still doesn't do that. Kind of shady IMO.
So, is the RM method for everyone? No, especially those that can't step back and question why they do what they do. I question many things in the RM method still to this day. I don't and won't use the Brightwell Alk, Ca, and Mg. Why?
BRS 2 part showed better in the ICP testing they had done. It also cost me $90 for 35 gallons. That will last me 2 years at my current consumption. Lol that is dirt cheap.
I've rambled on long enough. Read the handbook. Look at the thousands of successful tanks running RM and make your own decision. Those of us ACTUALLY using the program, love it.
