Review on Lees Premium Undergravel 12 Inch 48 Inch by Tiffany Stone

very good! This corrugated plate can hold a lot of weight, and the creases help hold the substrate in place better than the flat trays found at most stores. Underground filters are ignored by people these days, but I've used them for years with a canister filter that sends returns. Water back into the plates, this forces it to be consumed and floats above the substrate to be collected, but the canisters soak up the filter. It is also a very efficient method of circulating the water very evenly as the water rises from the bottom and is not poured back through a pipe hanging over the back as it takes a very long time to replace 100% of the water. Volume, as there are always dead spots. In addition to using a built-in external heater such as Hydor, large volume tanks maintain a very even temperature distribution throughout the tank compared to a tank heater. Because all the warm water enters at once, spreads out in the ground, and rises evenly, there are fewer cold spots. Therefore, you can try these commercially available soil filters not as filters but as return water plates. used with canister filter.
