Hi guys, just wondering, I am from South Africa and I just wanted to get a rough idea on how much sonar one or aquathol will cost. As i have a huge problem with hydrilla in my dam. thanks
Dylan - beware that fluridone (the active-ingredient in Sonar, Avast & Whitecap - all are priced differently) is seldomly used for spot-treatments. The entire body of water must typically be treated to achieve a lethal parts-per-billion (ppb) concentration for an extended period of time (45-90 days). Even Aquathol usually requires 48+ hrs of contact-time at a lethal concentration to achieve decent results. So, be sure you know how either product fit your scenario before investing any bucks.
