Now, this is yesterday. Looks a lot better to me, I've added a lot of landscaping. Euphorbia and junipers and sedums, one water lily (that can be seen yet), I've got some orange cannas, water willow, and bullrush in the pots you can see. I picked up a bunch of sale succulent houseplants in tiny pots, many of them are making really cool annuals, some failed. Got some dwarf papyrus, dwarf hyacinth, horsetail rush, and taros, one pitcher plant managing even though my water stays slightly basic.
My filter works pretty well, I think. When I first set it up, I poured a half gallon of ammonia in. within three days, I could not detect any ammonia in the pond. Still can't pick up any ammonia with a test kit, ph is about 7.6, no nitrites and very low nitrates. I do think I've got some phosphates in there, plants haven't developed enough to block sun or pull all the phosphates out. Yet.
No UV in here, though, and my water is not really green. I think the plants will eliminate need for UV as they get more mature, any comments on this are welcome.
