When I had 1/2" PVC, the flow into the tank hardly made a splash. And that was with two 500-GPH pumps running simultaneously. Now the flow is fantastic. I havent measured it yet (and didnt then), but suffice to say it disturbs the water plenty. If you think pump power is all that matters, think again. Youll get much more flow out of the same pump with a larger diameter pipe.
I did this the day before taking off for a two-week vacation, and was pleased to find the water crystal clear upon my return (yes, I do have someone around who checks on the system).
There is not a lot to update right now. I am waiting for a Matala filter system so that I can install some floating raft beds. Turns out my order (placed in early December) was lost and so I just reordered. I considered making my own filter system, but after checking out Matalas materials and their own purpose-built filter box for the filters, decided the cost-value of designing my own wasnt worth it. Im getting the basic model, without the UV light. Thats only necessary for aquaculture-only systems and dont think the bacteria would enjoy the UV light very much.
In the meantime, this weekend I removed all the basil plants in grow bed #1 and replaced them with lettuce and cabbage. The basil was ready to go and the only reason I ever planted as much as I did is because at the time I had to plant something and thats all I had. It will be interesting to see how the lettuce and cabbage grow in the gravel grow beds and then see how they do in the floating raft system.
Heres a video of the first basil plant coming out. I was impressed by the root system.
And here are some pics.

This video is just a quick update on what Ive been doing:
New 1" irrigation piping, and sump in background (note clarity of water)
Fish Tank. I know, the fish werent cooperating, so they are not in the picture. But, you can clearly see the air diffusor disk at the bottom. This tank is 70cm tall (27") and the bottom and sides are a dull grey. If they were white, youd really be impressed. :)
