This newly released addition to our AquaSphere product line is 100%  natural. It‘s the same great product just with less hassle, you just gently toss the sphere in your pond and forget about it.  Sphere ships complete with PROFormula. Will treat fresh water ponds and lakes for up to 30 days. Remember to add a new sphere to your pond EVERY 30 DAYS to continue to treat throughout the pond season (water tempertures from 45 degrees and above).  You cannot over treat water but under treating may not yield desired results.
