Since my grouper started complaining about his 3k pond not being "good enough", I give you his new 15k pond. The project started around November of last year and was completed in May. Below are some pictures of the build... Laying the concrete Bridge into sit down area Equipment Room I was trying to find more pictures of the build right before we added the pebbletec/water but they might be in another HD somewhere. The pictures do not do it justice so I'll be posting a video soon!
