Hey Kristen!

Looking good!!!

While I was reading your posts, I was thinking about my experience as I used both silicone and pond sealer in different backgrounds. In my experience the sealer was much better, even in the waterfall that has water running all the time through the background, the coco peat is still there, stuck like a rock!

I love the look of the coco peat covering the background! It makes it look very natural! If you can keep it moist, moss looks great on it too!

Looking forward to see it in the tank!
