Seachem Flourish Nitrogen 500ml

I think this was the key nutrient my plants lacked. I thought they were getting enough from the fish but no, a big tank and micro fish needs a little bit supplementation.

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.

Love the whole Flourish line. This and the others keep my plants in my tanks healthy and thriving. My plants say thank you

it will raise you nitrite level so be careful of how much and how often you use you can kill your fish with this

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)

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!

Good price

Received with no cap, punctured seal and no liquid. Shipping box was wet and green from liquid. Should I bother returning empty bottle?

Outstanding balance for my living plants.

Easy to use words great
