So to continue?
Once we have the right weight sorted out, the next part can be the tough part or the fun part. We begin to make room for something for the plants to sink some roots into. We will assume that we each have a favorite and I don't want to change that but you do need a place to put it.
So I took the weight off, turned the wood over and began to remove the inside wood to make a hollow space. Drill hammer, chisel or whatever you feel works for you. For me drilling a series of holes was right.
One thing to keep in mind is to not get so busy removing wood that you forget to save some space for screws to hold the weight on the wood. I found two screws were enough. While deciding where and how to screw them together, I went ahead and drilled both.
While drilling, I also added some holes on the top side for the plants to come through. The idea is to have the roots protected so, plants on top , roots on the bottom?
I had chosen a couple swords as likely easy plants for this as they are tough guys and they also have a nice set of roots which makes them really hard to pull. But those big roots make them a bit awkward to get stuffed in the top holes so I had to work out a trick to help. I found wrapping a piece of paper loosely around the roots made a much easier job of fitting them down through the hole.
With the plant in the wood, I turned it over on a small box full of paper so that it kind of held the plants in as well as held the wood in a position where I could work on the bottom.
Pretty simple job now to fill the bottom with planting mix of your choice. I used Flourite and sand with a Flourish pellet added, placed the cover/weight and screwed it down.
A point to mention is trying to be somewhat organized and quick once you get the plants out as drying is never really a good idea so the less time the better.
All done, ready for the tank.
Since my wood had already been in the bleach soak and I knew it to be safe, into the tank it went!
With the weight covered with a bit of sand, etc. it is now complete and ready for fish inspection!
