Morpheus77 Posted August 6, 2022 Share Posted August 6, 2022 I was thinking of using this as a substrate in the new 20 Gal Long, but have read some reviews from 8-10 years ago on other forums, about it containing iron due to being part volcanic rock. Seems it can scratch glass when using mag cleaner, others have talked about alk issues, etc. Has any of that changed over the years? Anyone use this brand specifically? Issues? Likes?

NoOneLikesADryTang Posted August 6, 2022 Share Posted August 6, 2022 I’ve never used it, but I’d imagine it’d be a nightmare to try and keep clean, unless you don’t run any whites. Quote Link to comment
joshthebox Posted August 6, 2022 Share Posted August 6, 2022 It is easy to clean. I will say that some granules in the sand are magnetic , which can mess with vortech pumps if you run them. Quote Link to comment
OfficeReefer Posted August 7, 2022 Share Posted August 7, 2022 @Morpheus77 @joshthebox is correct. It's not difficult and yes, some indeed have ferrite in them. I would caution though on the tank if it doesn't have enough flow as it's difficult to gauge how healthy the bed is. I would not opt for a deep bed with this for these reasons. 2 Quote Link to comment
