## Questions & Answers

**Q: I put a lot of pond soil in my ponds for the plants to root into, is this safe from the sludge clear?**
A: Sludge Klear is ok to use in these circumstances

**Q: The sludge clear will not remove the soil at the bottom of the pond will it? I don't want that to happen.**
A: No, it will breakdown unwanted organics at the bottom of the pond, but will not breakdown soil.

**Q: I have foam on the surface of my pond..for 2 weeks now...will these products get rid of it?**
A: They will help, but you may need to use a blanket weed remover as you may have a build up of sludge and blanket weed at the bottom of your pond, you could also use barley straw which should help. And if you have pond pump and filter, it may need cleaning out.

**Q: After using sludge tablets a lot of my pond is covered at the top in sludge. Do I leave it or remove it?**
A: The Sludge Klear will have broken up the sludge (which is a good thing) and if you have a pump and filter it will catch it and remove it.
If you don't then fishing it out and putting it on your compost heap is a good thing to do.
Do not leave it by the side of the pond as it will leach back into the pond
