Clear Water Again.

Well the fish bed is crystal clear again and the fish are much more active, at least I can see that they are more active. I added a bin above the grow bed to raise a little duck weed. I was hoping that this would filter out a lot of the algae that bloomed last week. So far it has done pretty well, but I don't think the plants I put in are duckweed. They are strung together on a soft stem and have roots. I will have to look into this further. Here is a picture of the duckweed bed.

Below is a picture of my fish bed before I starting the filtering process.

And here it is after. The duckweed container has a standpipe that empties into the grow bed below it. The standpipe seems to help with the algae issue too. I am also using a bio filter mat under the standpipe from teh duckweed bin to collect solids. 

This week will be an experiment in duckweed growth and keeping algae from growing in the duckweed bin as it will be in the direct sunlight all day. I also need to find a source in Mobile for some duckweed. 

This is as example of the plant I picked up at Langam Park... Shhh don't tell. It was in a still pool not connected to the lake, but standing water off by itself. Duckweed looks like it is individual leaf clusters so I am thinking this is not it. If anyone knows where to find duckweed in Mobile, please let me know.
