Easy fertilizing to promote algae
I'm new here! Generally I go with very low-tech set-ups and don't really do much in the way of ferts and keep plants that are happy with crummy lights and eco-complete.
I have a fairly new set-up and I'd like help in growing algae. The tank is a 20 gallon long housing "rainbow-colored" stiphodon gobies. Shortly I'll be adding a few Reticulated Hillstreams as well. I have 40W of T8 light on it.
While cycling, I seeded several algaes and left the lights on almost all the time. The cycling process produced nutrients and I also dosed with plain old Schultz 10-15-10 liquid plant food. I now have nice brownish red algaes covering my rocks (not all diatoms, I don't think) and some nice green ones coming in as the browns get eaten. I haven't dosed any of the Schultz since the fish moved in, as I'm unsure of its safety.
The tank gets plenty of oxygen from an oversized HOB filter plus a powerhead with air coming in. I don't do any CO2, but can add Excel if needed.
I have a couple of small anubias, a few java ferns and some mosses. No other plants. The Anubiases are gloriously covered in algae, and I'm hoping the java ferns follow suit.
I have three questions:
1. Can I use the Schultz, and if so, what should my dosing be?
2. If I can't use the Schultz, what's the easiest way for me to fertilize the tank to encourage algae growth. Easy is the key for me.
3. I have some plain old Flourish. Should I be dosing that as well? And at the recommended level?
