. And plant wise, I plan to have at least 65% of the pond covered in duckweed and lilies at all times and then bunches of anacharis below. Do you think I should add a layer of gravel at the bottom? It would help with the planting and it would hold beneficial bacteria, but then it would mean I would have to vacuum it, which would be a hassle. I found a pump on ebay that is pretty cheap: http://cgi.ebay.com/375-GPH-SUBMERS...ultDomain_0?hash=item2c52151e5b#ht_5508wt_810 but i won't buy it till i'm sure this is going to happen. There are also a lot of solar powered pumps that are for decorations, I could cut mod those to fit a pvc pipe and the filtration could only work during the days, saving me a some money on the energy bill, but just a thought.
