So, every year we battle with green water in our pond. Currently the only life in it is 3 average sized water lillies (they may spread 3ft in the summer) and random tadpoles. The water is filtered with a filter that uses bioballs (and thats about all that I know about it...) and a UV light. The pond gets full sun all year long, and winters are not cold enough to freeze it. We live in zone 8. The pond is 6X6ft square shaped, with a depth of 3 feet. Using that, I figure its about 800 gallons?
Am I correct to assume that part of our problem is that there is nothing in the pond to take up all the nutrients that the sunlight provides? We have a "food" factory, and nothing to eat to the food... If this is so, my plan is to plant the bejesus out of that pond, but I'm not entirely certain how to go about it. I've looked at several places on line, and I think that we need extra coverage of the water, so I plan to add floating plants. Water hyacinth and frog bit are on my list, do you all think that these plants would be a good addition? I'd especially love to add the hyacinth- which is legal in our state, thankfully. For submerged plants, I wanted to pick easy plants, since I'm just getting started with aquatic plants. Anacharis, hornwort and possibly java fern are on my list for submerged plants, as they seem to top every list of easy care plants I've seen, but I've never really seen the java fern used in ponds, will it be all right in one?
Can anybody give me some advise on how the plants sound, and about how many of each might be good? I'm figuring 9 of each of the Anacharis and hornwart, and maybe 5 of the java fern, as I've seen in my own tanks just how fast it can grow and make new plants.
And lastly, I really want to add in fish, preferably just comet or common goldfish, and koi are quite expensive here, and my father has a bad habit of killing our fish (which is why he is not longer allowed to add anything to the water without asking me about it first
). I need something to help eat all the algae, right? Snails aren't really on my list, mainly because every algaecide I've seen warns that it will kill invertebrates, which would be counter productive.
