Hello everyone I am trying to make a diy algae scrubber and I found that there are two types: where the water drips/falls over the algae's growing media and one where air bubbles over the algae's growing media. So here is a question for you who have experience with this contraption: which one works better? Drip-down type or bubbles type? Thanks
Also which stores do you recommend for finding the knitting canvas on which the algae grows on? I can't find any.
