Now you might think that a new lid is not a big deal but I’m amazed by how much I love it. It’s custom made for my 1200 open top in three sections out of 10mm acrylic. It replaces my jump guard which was quite scruffy and hard to manipulate on the big tank it kept the fish in but nothing for evaporation which this new one does. It just looks so neat too! I got it made with cut outs for my plants too and for the empty ones I’ve got the infill too.
