I've read in threads about people using vitamin supplements in their tanks and decided that's it's time for me to start. I took a look on the Big Al's website and saw a bunch of different brands with different vitamins and supplements in them. I've narrowed it down to 2 that I think would be the best but can't decide which one would be best. They are Seachem Nourish, since I know Seachem has quality products, and Boyd Vita-Chem, since I recognized the name Vita-Chem from seeing it in different threads. So which would be the best one to get? Feel free to suggest another one if you think it's better.
I have and will be having: gouramis, tetras, cory cats, rams (probably german blues since that's all I can find in my area), a
betta boy, and possibly a clown pleco and odessa or cherry barbs. (These are not/won't be all in one tank just in case you're wondering)
