I really like their products and all for reef is great! I was able to do acros in a 20 Nuvo with hand dosing. I did notice that when I had a doser for a bit it would clog the tubing .
You do have to check the individual parameters . I found my system was using more magnesium then the mixture so I had to add extra magnesium from the powder solution. Other friends noticed good color as well. That’s a good idea to maybe just use a more dilute solution . I would be curious to see what Lou has to say.
I really like Lou Ekus he doesn’t heavily push tropic marin and has a chemistry background but explains tank chemistry in a simple way.
