Hello. I am new here, and I was wondering since I have a 29 gallon tank and a 10 gallon tank and I have live plants and fishes (of course xD) and I was wondering. Would 20 W 6,500k be strong enough light for my amazon swords? It is also a high intensity lamp. I have an Aqua Clear filter (both tanks) and my 10 gallon I use two 15 watt incandescent lights, and I keep a few plants in there.. I also use Flourish Trace as a type of plant fertilizer for my two tanks. Usually helps with the plant growth.. Although should I fertilize my tank every single day or once every two days? I do a water change and gravel wash weekly. I have some fishes that do love to eat my plants. Including my Amazon Swords, which I am very concerned about because they don't grow back very fast. I hope anyone can help me with the problems. PS. I only have one Fluorescent light for my 29 gallon tank.
