Welcome to TFH!

I've used it before. What problems are you having?

Mopani root is perfectly safe for use in aquaria; I've had it in several tanks over the years. What issue(s) are you having? The only thing I can think of is that new roots tend to leech tannins for awhile and turn water brownish... It's not harmful to the fish or anything; some people may find it unattractive, though.

To put it simply, my water looks like tea! Lol, I did soak the stuff for 12 days with daily changes. It looked good on day 13 so i thought it was good to go. Planted some anubias to it then placed it......... then tanin city arrived on my tank! I'm just a stickler for crystal clear water, can't wait for it to go and was wondering if I have done something wrong/ or if there is a way of helping to process the tannins out??

Quite a few things you can do.

Water changes, water changes, water changes- lots and lots and lots of them. EVENTUALLY the wood will stop throwing so many tannins. Boiling the wood a few times can speed up this process. Chemical filter media like carbon and Purigen will absorb tannins.

I personally tend to go with all 3 of the above if the tannins are really bad.

I love Purigen filter media since you can recharge it with some bleach and keep re-using it, unlike carbon, where you just have to keep buying more.
