Dennerle Crystal Quartz Gravel (5kg) Diamond Black
Dennerle crystal quartz gravel is a classic in the range – for many decades one of the best gravels you can use in your aquarium. The excellent appearance and perfect biological function of the Dennerle crystal quartz gravel, which does not harden the water, are probably unique in this combination.
Dennerle Crystal Quartz Diamond Black Gravel is lightfast and CO2 resistant, can be used again and again, and retains its color even after years. Due to the iron oxide coloring, the quartz gravel is water neutral and guaranteed free of pollutants. The grain size of 1–2 mm suits bottom-dwelling fish and reduces the risk of dirt in the gaps.
The fine quartz Dennerle gravel is also very suitable for plants with fine roots. The use of rounded grains greatly reduces the risk of aquarium animals injuring themselves. The very small gaps that nevertheless exist provide a perfect settlement area for important bacteria. Dennerle quartz gravel does not need to be pre-washed.

Just Ok.
Size: 4 pcs: 15.7*5.7, Color: Maple Wood, Size: 4 pcs: 15.7*5.7, Color: Maple Wood
They look nice but they aren’t sturdy and do not hold much weight. I’ve bought better ones on Amazon.

Worth
Size: 6 pcs: 15.7*5.7, Color: White
Really good wall amounts. I used the drywall anchors and it feels sturdy. I put like a 3 pound Crystal on it and it’s holding perfectly fine. I also was able to paint them with no problem would buy again.

Excellent separation screen
Color: Dark Black
Easy to put together. A drill with the hex head made it easier. I see some of the photos in the reviews and it looks like the fabric is wrinkled and loose. However, when we put it together, the fabric was tight and it looked polished. Using this divider to separate a recording space from the rest of the room the overall look is nice. I would not use this in a living room, but it’s fine in another room. Once put together, it is pretty sturdy. The pieces that connect the panels together are plastic. We did fold it one time when we moved it and didn’t have any issues, but it is going to remain stationary so I can’t comment on folding it more than the one time. It is very lightweight and very opaque.

JUNK!
Color: Grey
This is the worst product in every way. I ordered a similar one previously and thought I was getting the same product which was great, no this is a piece of junk. I would have gladly sent it back but I needed it. I feel sorry for anyone who tries to put this together without any mechanical ability. I have plenty and it was still a nightmare. We will surely not be purchasing anything from this company in the future. The previous one I bought was a (Kecreque Room Divider). Is is a quality product!
