"I love this sand. It was perfect for what I wanted and looks great in my tank. My shrimp are gonna love it and I can’t wait to use it in other tanks."
"Just buy it! Worth the money, didn’t even really need rinsing, was not Dusty at all and it looks beautiful in my tank! This is the best substrate I’ve ever purchased. UNS is the best brand I swear!"
"Looks absolutely fabulous in my fully planted 75. The sand really brings out the vibrant color of the plants and even works great with the seiryu stone I've got. I completely miscalculated and ending up getting three extra bags from Amazon (I had a lot of credit) but turns out, I only needed three bags instead of the five I ordered overall. Oh well--just means I have an extra 50lbs for a new project. I'd definitely advise rinsing the sand before placing in the tank--I didn't have the capacity to do so (in a blizzard) but after a couple days with the filters running, it all settled down."
"You guys are so great, I have set up 2 aquariums in about a month and a half, I went all out on everything and I bought 80% from your company. The rest, I got from my lfs cause we gotta help them out to. Customer service is top notch, shipping is fast and reliable. I could write an article about how happy I am with our transactions. But I won't, I'll just say thank you sooo much GA team. And I look forward to doing buisness again soon."
"It is a very good looking top layer. Also makes the tank look complete. Perfect packaging, when I filled up the tank the water wasn’t murky. It’s very good about keeping the soil underneath."
"Love this tahoe gravel! Very beautiful and round edges are safe for my fish. Paired with Bora."
"Color was great, no need to rinse, perfect sand!"
"Great amount for the price. Looks awesome and works very well."
"Love the colors"
"I have built 5 tanks with various Controsand colors and Bora is my favorite for neutrality and highlighting plants and wood. It strangely enough looks great against white elephant stone. I've also used it with darker stone, such as seriryu. Works with everything. Very natural, like what you'd find walking the beach with light sands."
