Fertilizers & Supplements

I purchased "Easy-Life" profito universal plant fertilizer and Seachems Flourish nitrogen. The fertilizer contains 0.03% total nitrogen and a list of other elements. The Seachem product contains 1% total nitrogen and 2% potash. Thats much more then the Easy-Life product but has no other elements. I will be using both unless its a mistake. I would like some comments from the experienced plant keepers. My plants were installed two days ago. They consist of Dwarf baby tears, Anubias-coffeefolia, Ozelot sword and Wisteria.

I am not familiar with the Profito product, but from what I have seen on their website
Profito 500ml - EasyLife - Liquid Fertiliser - Fertilisers
I would expect it is a decent complete liquid fertilizer for aquarium plants, similar to Seachem's Flourish Comprehensive Supplement.

As for the Flourish Nitrogen, I would not recommend this. For one, this product is intended to be used in conjunction with their other macro-nutrients--Flourish Excel, Flourish Potassium, Flourish Iron--and Flourish Trace. Flourish Comprehensive Supplement ties these together. This is a lot of fertilization and not necessary in the average planted tank.

But more to the point on the Nitrogen, aquatic plants prefer to take up nitrogen as ammonium, and this occurs in an aquarium in the form of ammonia which is continually being produced by fish and bacteria, and from the breakdown of organics. In most fish tanks, there will be more than sufficient ammonia/ammonium to provide all the nitrogen that plants require. Adding it is only going to raise the balance for everything else, unnecessarily.

I will tie this together a bit more in my response in your other thread.

And before I forget, welcome to Tropical Fish Keeping forum.

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]
