Hello, relatively new to this place. Just a month ago, I thought I was going to have a nano high-tech CO2 tank with some nice lush baby tears or monte carlos, but nope, decides on a Walstad-esque method instead. My tank here is the Top Fin 5 Gallon Retreat (a little wider and more boxy than a Fluval Spec V, but still pretty good). I have a 1.5" organic Miracle Grow Raised bed soil capped with around 1.5" of 3.0mm to 5.0mm gravel. My plants are:
Wisteria - Hygrophilia difformi
Microsword - Brasiliensi
Now this is a low tech 5 gallon tank with the stock light + the Finnex Fugeray Planted+ clip on with no heater and the internal filter running. My livestock consists of:
x1 Ghost shrimp
x9 Neon tetra
x3 White cloud
x2 Unknown fish fry (guppy?)
The first day, nitrates and ammonia were all zero or close to zero, and the 2nd day, the nitrates creeped up to less than 5 or 10 ppm with ammonia still at 0 ppm. I've done couple water changes and will continue to do so on the first couple of weeks. The lighting period I give the plants are 12 hours from 8:30 AM to 8:30 PM.
I had a few questions:
Will there be a heater needed in this tank (the temperature hovers near a steady 72-75 degrees)?
The microsword seem to have some slight yellowing but I assume this is normal and the plants should spring back after they acclimate?
As for fertilizers...
What should I be dosing the plants with to help them out? I don't run CO2, so I wanted to slightly dose the tank with some Seachem Flourish Excel. I also realize I need to dose the tank with iron to maintain the Indica's nice red color. Are there other fertilizers I should be dosing this tank with? Just a reminder, I have a soiled tank if that changes the situation.
Much help will be appreciated, thank you.
