## Questions & Answers

**Q: What are the ingredients?**
A: ACTIVE INGREDIENTS: Copper Sulfate pentahydrate 1.02%; 1-dimethylurea 0.51%OTHER INGREDIENTS: 98.47% NOTE: Ingredients taken from package label.

**Q: How long until you start to see the water clear up?**
A: The length of time it takes to clear up the algae will depend on a number of things such as the overall water quality of the pond, the stocking level, your filtration, the amount of organic matter in the pond, and so forth.  The more organic matter, the softer the water, the less effective and more time it will take.  In a situation such as this, we recommend a partial water change initially, prior to dropping the blocks in.  For more assistance, please contact the Tetra Consumer Relations Team at 1-800-526-0650.

**Q: Is the block supposed to disolve? its been in my pond for two weeks and still the same as when it went in.**
A: No. That's why I like it. It gets smaller over time and takes about 3 - 4 weeks to disappear.

**Q: will the Tetra Pond Anti Algae Block work in a 40 gallon aquarium that has 2 turtles
that are 30 years old.  Will it harm them.**
A: I use it in my goldfish pond. And my box turtles have access to it. No harm has come to either animal as long as the water is aerated.  This product removes the oxygen from the water.

### ⭐⭐⭐⭐⭐ I decided to try these algae control blocks and am glad I did
*by H***A on June 13, 2016*

Update 6/15/16- I have already purchased my second package of these, I am that happy with the results. I had to use a few to get it going, and then I think my turtles ate one! Seriously, it was only half dissolved this morning and now it is gone. They are acting fine, added a new one up on the waterfall so they can't get at it this time. I will never be without these again. Will look into getting the big tub of them next time.My pond was a big green mess. I previously tried barley bales and liquids which did nothing at all. I decided to try these algae control blocks and am glad I did. I just received these 2 days ago, and already I can see my fish, turtles and the bottom of my pond again. Still has a ways to go to be totally clear, but I am amazed. I dropped 2 of these tablets in along with one of their sludge reducer blocks. My pond is not large, it is a preformed plastic one we bought at Home Depot, I think 250-300 gallons. Nothing I have ever tried has worked, summer is the worst, full of algae all season long. As well as being able to see to the bottom and my animals again, the walls of the pond are clear from the thick algae that was growing. I don't have any plants in my pond, as the turtles eat them the instant I put anything in, so I can't speak to the safety of plants but the turtles, goldfish and mosquito fish are all a-ok.I know, it doesn't look great, but if you had seen it before... Fish and turtles were not visible 2 days ago. I will post another picture/time frame once it is clear. Second picture you can see the bottom of my pond. Still needs to clear up a bit, but after 3 days the bottom of my pond is visible again!
