## Questions & Answers

**Q: Is this suitable for a community tank with Vallisneria which is going a bit brown? I have root tabs already**
A: This is a good fertiliser to use if you have an excess of phosphate.  This might be why your Vallisneria is turning brown, although there are of course other causes.  I have used it for months and it does not cause any problems with fish or shrimp.
