I have a 16 gallon bucket for a four plant set-up and a leftover water pump from a flood and drain set up I chose not to run. I hooked some hosing up and ran it up through the top of the container and back into it. The pump just picks water up from one side and drops it into the other. I am hoping this will circulate water and distribute nutes/ph adjustments more readily. A. Is that going to help? B. The hosing is clear, should I tape it up for light seal? No light leaks into stagnant water, and I was hoping the algae won't be able to materialize in strong rushing water. C. Thanks dudes!
