## Questions & Answers

**Q: I was using Phosguard in a Freshwater tank that has a problem with Diatoms.  Now my Java fern is turning yellow and leaves are dieing.**
A: Java ferns are leaf feeders. They love phosphates.

**Q: can it be use on hang on back filter? with high flow rate?**
A: I don't see why not, it may reduce the flow some, but if you are having a problem it truly helps.  We do a water change once a month and change it every other month.  Our tank looks better and the fish have been healthier. Good Lock !

**Q: I have some brown algae on my sand bed and green algae on my glass in my 20 gallon lps reef tank. will this help? can it hurt my tank in any way?**
A: Brown algae (diatoms) & green algae can definitely be affected by phosphates & silicas.  It won't hurt your tank at all.

**Q: is this more or less the same as using chem-blue?**
A: No.
