There's plenty of space, Tim.

Updating website now, thanks Arlene!

Arlene, do you have an exact address for this?

FYI, some Pittsburghers mentioned that they will be attending, and bringing some more of their awesome sand.

Gratiola viscidula is threatened in our area, but native to Maryland/Virginia. There are places in Maryland you can collect Proserpinaca if you want to try the local version. It's a beautiful aquarium plant.

Josh - lead the way with your MiracleGrow experiment. I bet it'll do wonderful things for growing algae!

Viktor is right -- the best is to have substrate that will keep the ferts (regardless of miracle grow or others) in the substrate. So, large gravel with lots of water flow through the substrate would not be ideal, but Flourite Black, Sand, Aquasoil, etc. should be fine.

Looks really nice, Will! Thanks for sharing!

Definitely don't mix your phosphate into your iron or traces. In general, you can get down to two solutions, one for macros and one for micros. In terms of removing tediousness, I found using measured pump bottles very helpful. They typically deliver 1-2ml of solution per pump depending on the bottl...

I've never used powder for carpets. Maybe the smallest Eleocharis might like it, but otherwise just use the regular stuff. If you really need fine grain, you can mix in inert sand.
