    This fertilizer comes in very handy in a 10 gallon single betta tank with very light nitrate bioload. I use the complete Flourish line following their suggested weekly dosing regimen and my plants are absolutely thriving!

    Dosed this according to instructions in my heavily planted, co2 injected 10 gallon, and within 3 days I lost two fish, a harlequin rasbora and a gorgeous black orchid betta. I had zero fish deaths in this relatively new tank prior to this. Naturally, I dont know for sure that this is what caused it (although it was the only change Id made recently), but with such a strong coincidence Im reluctant to use it again. Prior to using, my parameters were 0 ammonia, 0 nitrite, 0 nitrate. I suspect that if anything, it wasnt the product but the sudden change that killed them. My remaining harlequin rasbora does not look happy, either. Hopefully it will pull through.

    Beware!!!...use with caution!!! With a heavily planted and stocked tank, i decided to give this product a try. I dosed according to the beginners dose with all parameters wnl (weekly water change earlier), putting it in the tank before bed....my bad on that (perhaps i should have dosed during day with lights on) because i woke with 2 dead parrot fish, 1 ghost knife, 1 chinese algae eater and 1 black skirt!!!!! A quick water check revealed nitrates off the chart!!!!....lesson learned: leave this product alone (for me)

    Is what it is. No frills.

Nitrogen is one of the main three macro nutrients (nitrogen, phosphorus, potassium: npk) required by plants and can often become the limiting factor to growth in a flourishing system. Flourish nitrogen is a concentrated (15, 000 mg/L) blend of nitrogen sources. It provides nitrogen in both the nitrate form and the preferred ammonium form. However, no free ammonia is released because the ammonium in flourish nitrogen is complexed and unavailable until utilized by the plants. Ammonium becomes available after conversion of urea (carbamide). flourish nitrogen also provides nitrate for those plants that can readily utilize nitrate as well. For Maximum benefit, use with flourish Phosphorus and flourish Potassium. Flourish nitrogen is safe for invertebrates such as shrimp.
