Product Overview

SeClear is a potent algaecide formulated to be an all-in-one solution to scum or toxic cyanobacteria in backyard ponds or lakes and reservoirs. This formula works as an algaecide and a water enhancer for better water management and improvement. Unlike other algaecides, SeClear reduces phosphorus content in the water which eliminates the vicious cycle of algae regrowth and algaecide reapplication. Apart from algae control, intervals between applications are much longer with this product and follow-up applications are much smaller as time goes by making it the cost-effective choice for an algaecide.

Questions & Answers

Have a question about this product?
Is SeClear Algaecide ok to use in a pond with fish?

Per the SEClear Algaeide label you should only treat ½ of the pond at a time, as there will be oxygen loss when killing off the algae and weeds.  To prevent harming the fish you should begin your treatment along the shore and move outward in bands so that the fish can move into untreated water.  Wait 14 days and then treat the other half of the pond.
