So Im wanting to start a project and looking for some advice...I want to start creating some synthetic rock formations using portland and sand for the purposes of LR/ aquascape creations...Ive done all of the research and am building a Plywood tank for curing the pieces and seeding coraline... I would love to make them and give them out for........... FREE TO ALL MEMBERS WHO WANT THEM..... Im just curious does anyone have a very large skimmer and pump for current that I could BORROW, to cure all this for a couple of months?? :thumbs:
