b'This Wednesday Pro Tip comes to us courtesy of Giuseppe! It\\u2019s using pumice as a base layer in your substrate and it makes a lot of sense. \\xa0 If your aquascape calls for a thick substrate and you\\u2019re wallet is starting to hurt because it\\u2019s going to cost a lot to use 100% expensive substrate, think about using a base layer of pumice to build it up. Then cover this layer with the substrate of choice. \\xa0 This is a great idea because: 1. Saving money because it\\u2019s cheap and easy to get. 2. It creates a great environment for the microbes that are necessary in the substrate \\xa0 It doesn\\u2019t have to be pumice. You can also use ceramic rings like the ones you put in filters. Really almost anything that\\u2019s inert will work. \\xa0 Thanks, Guiseppe! \\xa0 If you have a tip that you want to share with your fellow hobbyists, pay it forward and send it to us at feedback@scapefu.com.
