Well lucky for me all the timber I got from a house being demolished. The ply cost was £125 all the fibreglass flow coat and tools to apply £256 and the glass was £490. So under a £1000 bare in mind I live on an island and everything is more expensive to get hold of. Hope this helpsGreat looking tank. Expansive viewing window. Fiberglass looks great. Im interested in knowing expenses with this build vs. what it would be in conventional acrylic or glass.
