First time assistance with fertilizers
I was hoping someone could set me up with some basic first time advice in dosing fertilizer. Here's what I have..
6 gallon Fluval Edge with stock lights
Regular aquarium gravel
A few guppies and otto's. Otto's have been in for about two weeks, guppies for about 2 months.
No ammonia, nitrites, and very little nitrate. I do a 25% water change weekly
So far I have one plant, Anubias Nana (I suppose) planted slightly above the gravel. It's been there since I first set up the tank in mid-december. I now know the rhizome should not be planted and this is 99% above the gravel. It's not dying, but it's also not really growing. Some algae was having its way in there but the otto's quickly dispatched it.
I have needle leaf java fern, anubia petite, and rotala (not sure what kind) on the way. I plan on planting the rotala and anubias in the gravel and attaching the fern to driftwood.
Currently I have no fertilizer whatsoever (aside from fish waste), a fairly low light situation, and no CO2.
Do I even need fertilizer because of the low light and no CO2? I read about the triangle of the the three (nutrients, CO2, and light) and that made me question it.
If so, would liquid fertilizer (like a flourish) do the trick for both kinds of plants (the fern which sucks nutrients from the water and the rest from the gravel) or should I do a root tab and a liquid. I was thinking about doing plain old Flourish and maybe Excel due to lack of CO2. I know they're not a comparison, but it's probably better than nothing.
Sorry for rambling so much. I'm just really seeking some assistance in which route I should go and what to use for my situation. I have low light, no CO2, a relatively light bio-load (I think)and undemanding plants, but I still want to assist them in remaining healthy even if growth is slow. I know dry fertilizer is cheaper in the long run but that's for another time. Really, the end question I guess is root tabs, flourish (or its equivalent) and what kind of it. I know they have like six different kinds but I suspect I really don't need them all for this situation. I've read a significant amount here, but I have to admit. Still confused. Any assistance is appreciated.
