seachem flourish

Do I need to use seachem nitrogen if I am already using flourish? I have a low light no co2 tank with moneywort, pennywort some crypts and some amazon swords.

That depends on your fish load... However you'll probably require potassium (K) first.

Flourish comprehensive (commonly called flourish) is mostly micronutrients, it has very little NPK macronutrient content, although it does have some.

Your fish waste will contribute nitrate (N), and phosphate (P) to the water, but how much they provide depends on how many fish you have relative to your plant volume.. Fish waste rarely provides enough potassium (K).

A 55 gallon tank fully loaded with fast growing plants and a single 2" fish in it is going to need full NPK fertilization, as well as micros, even if it is just low tech.

The same tank with full stock of fish might not need N and P if it is low tech, but probably needs K and micros. (High tech generally requires NPK+micro no matter how heavily stocked with fish, but you're explicitly not high tech here)

There's a wide range of possibilities between these extremes, even when staying in the low tech world.

Save yourself some money and go with dry ferts, they will last you a very long time for the amount that you spend on one round of seachem ferts.

+1, unless you've got a very small tank, liquid fertilizers quickly become expensive, particularly if you want to use them at reasonable rates used in most dosing regimes (ie: much, much higher than seachem's "beginner" label rate).

nilocg, who sells over in the for sale forum here... I can't/won't vendor review him here, but you can always look up the ptrader feedback I and others have left for him (mine is kinda old, 11-1-2014).


If you want a more commercial site, some here seem to use GLA, but I never have.
