Thanks Steve, I don't do litres or gallons Sounds a bit too tall for my shelves though. My current tanks are about 19 x 12 inches and 8 or 9 inches tall, so the footprint of those is fine but they'd probably not fit height-wise. Where's the best place to get the 5mm mesh now as B&Q seem to have stopped selling it here?
Ive used those ones from morrisons, its just a walk away form my house and I dont drive so its sometimes the only option. Mine seems to have sold out and haven't restocked which is annoying as i found those tanks an ideal size for a trio. They are a bit too tall to put on my shelves though, thats the only problem.
Thats true-I had a good sort through in the shop (people must have thought I was crazy) and found some which clipped in porperly, there were quite a few which didnt! Because its quite thin plastic on the lid it was much easier to convert it into mesh.
