I don't have any lights right now, I want to know what to get before I order it, I'm looking on Amazon.nutrients for beneficial bacteria? that’s a new one lol.
Technically, yes they do help with cycling a tank. Plants prefer to use ammonia as a nutrient source(over nitrates), but they’ll use any source.
You can do it whenever you’d like, they’ll help somewhat with the cycling process, but not by alot, unless you heavily plant it from the start. And since you’ll be using cycled media, you don’t have to go through it.
Any light with 6000-8000 kelvin rating will work, those plants you mentioned would do best in medium light. What light do you currently have?
Its a 29 gallon tank, about 17 inches deepNow your second question. Lighting as mentioned 6000-8000 kelvin is needed for those plants to show good growth. What size tank do you have and how deep is it? Both the crypts and swords will benefit from root tabs and liquid fertilizers.
I was looking at the nicrew lights and managed to find some that should work, as for the CO2 will I need Injections?OP, As long as the plants have decent lighting, a food source, and carbon dioxide in the water, they can go in. I got the DA FSPEC for my tank and it works wonders. I’ve heard good things about nicrew as well. Nicrew will be cheaper.
