Craziiininja Posted June 27, 2021 Share Posted June 27, 2021 i got this driftwood for my 125g planted rainbowfish tank. 2 pieces are mopani and the other branchy one is mangrove root. My questions are is mangrove root safe to put in aquariums? Also how long would it take to get most of the tannins out of the pieces of mopani. The one on far left is over 20 inches tall and the middle one is a pretty thick piece of mopani. I can not boil them they are too big and heavy. I'm concerned about the tannins lowering my ph. My ph is 8.0-8.2 gh 12 kh 10. I know people use driftwood for softwater fish but every rainbow tank i see has driftwood in it. Thanks for any help 1 Link to comment Share on other sites More sharing options...
tonyjuliano Posted June 27, 2021 Share Posted June 27, 2021 (edited) With measurement of 10 kh, it would take far more than wood to alter your ph in any appreciable amount. And the mangrove will do no harm. Edited June 27, 2021 by tonyjuliano 1 Link to comment Share on other sites More sharing options...
lefty o Posted June 27, 2021 Share Posted June 27, 2021 the larger pieces of mopani with really dark wood in them can take several months before they quit staining the water. id soak them in 5 gallon buckets for a week or so changing out the water a few times. that will get a good portion of the water staining tannins out. they will still leech color, but in a larger tank it will be less noticeable than in a smaller one. 1 Link to comment Share on other sites More sharing options...
Craziiininja Posted June 27, 2021 Author Share Posted June 27, 2021 I have them in a 35 gallon tub they wont fit in buckets. Does mangrove root release a lot of tannins like mopani? 1 Link to comment Share on other sites More sharing options...

lefty o Posted June 27, 2021 Share Posted June 27, 2021 the dark chunks of mopani are pretty much the worst in my experience. 1 Link to comment Share on other sites More sharing options...

lefty o Posted June 27, 2021 Share Posted June 27, 2021 not to worry, it will take some time, but those are going to look really good in a tank. 1 Link to comment Share on other sites More sharing options...
Solidus1833 Posted June 27, 2021 Share Posted June 27, 2021 you can always try the tile method after you soak them in a 35gallon tub/trashcan. drill holes through some tile, and use zipties to attach them to the wood. depending on your substrate, it may have enough surface area and weight to keep the wood sunk. I've always struggled to get my large pieces of wood to sink. even after boiling them in a large steel vat using some propane outside. they still floated. so you may still need to weigh them down. OR!, I've also seen some examples, where putting up a new aquarium, and they glue/epoxy the wood to the bottom glass using the tile method as well. 1 Link to comment Share on other sites More sharing options...
lefty o Posted June 27, 2021 Share Posted June 27, 2021 mopani will stay down on its own, it is a very dense wood. 1 Link to comment Share on other sites More sharing options...
GameCzar Posted June 27, 2021 Share Posted June 27, 2021 Instead of making my own thread, can I piggy back on this one to ask about spider wood as far as tannins and density? Link to comment Share on other sites More sharing options...
lefty o Posted June 27, 2021 Share Posted June 27, 2021 spider wood doesnt have too much tannins. most commonly encountered with spider wood is a white fungussy growth for a few weeks after putting it in a tank. 1 Link to comment Share on other sites More sharing options...
Craziiininja Posted June 28, 2021 Author Share Posted June 28, 2021 I second that on the spider wood. I had smaller pieces they didnt release a lot of tannins. 1 Link to comment Share on other sites More sharing options...
