Twantyniner Posted July 31, 2016 Share Posted July 31, 2016 I have downgraded from a 29 to a 20 gallon and did not bring the sand into the new tank. I had about an inch of that "black" live sand and it had a lot of different sized pieces making hard to vacuum which would have caused me issues in the future. Also the white particles included in it drove me crazy! I don't really care for white sand and I have thought about that nature's ocean yellow sand but I prefer something I can easily vacuum. In the 20 gallon I have been running bare bottom. It is so nice to easily siphon out all detritus and my parameters are looking great! However, It just doesn't look right to me. I am wondering if anyone has experience using a single type of fast growing coral as a substrate? I was thinking of something like green star polyp. In the future I would like to add other corals. Any input or discussion is hugely appreciated. Link to comment
seabass Posted July 31, 2016 Share Posted July 31, 2016 Green star polyps would cover the bottom, and all the rocks. Maybe try a black sheet of HDPE: https://www.amazon.com/Seaboard-Density-Polyethylene-Finish-Length/dp/B00K2QT1XO/ref=sr_1_4?ie=UTF8&qid=1469930135&sr=8-4&keywords=hdpe+sheet Link to comment
Twantyniner Posted July 31, 2016 Author Share Posted July 31, 2016 Oh I like that idea! Link to comment
seabass Posted July 31, 2016 Share Posted July 31, 2016 I'd probably use some black silicone around the edges, so that detritus doesn't get trapped on the sides and underneath the sheet. I think 1/4" material would be sufficient, but there are thicker sheets if you prefer. Link to comment
