I purchased a pallet of Southern Excellence and put it around in some of the ponds I keep fertilized. It is simple to use and is working great. the best thing about that product is you can remove the fertilizer if your bloom gets too heavy. sometimes (for whatever reason) the bloom will get very heavy even though proper fertilizer rates were used. In the past I just had to ride them out and adjust rates, usually during the summer. this has happened to me a couple times this year and Southern Excellence makes this problem easy. you simply take the bucket out and set it on the bank, after a week or so as the bloom clear you can put it back in. cant think of another fertilizer that you can take back out. I will be using Southern Excellecne from now on.
