    Perfect supplements!

    I have used the APT F, APT P, and the comprehensive planted aquarium supplement (micro and macro nutrient rich) They are all three the most wonderful all-in-one solutions I have ever tried. The APT F is the only things aside from flourish that has gotten RID of my BBA outbreak without having to break the tank down, bonus! The APT P is a water conditioner an it works like a charm! And finally the fertilizer, comprehensive planted aquarium solution, is the greatest thing ever invented! My greens are super green, the reds pop, and the growth rate is out of control! It feeds my substrate feeding plants, as well as my water column feeders. Even slow growing plants seems to speed up their processes when I add the fertilizers. I have accidentally overdosed on the APT F, and the APT P, the good news is that it’s very hard to overdose the tank and end up with negative consequences; so it’s nice to know that the products I’m using are super safe for my aquatic inhabitants! I recommend having all three in your arsenal, how can you get by without it?!
