[??]Need Help!!

[DelawareBass-R]

Well, i need some fishing advice. I have been fishing this one pond for a while now and have got it to where i know where most of the fish are, what time they like to feed, etc. Now this pond is small(5 acres) and is loaded with algae(always has been), so the state put about 10 chemical nets in the pond to gather algae, and kill it. But, about a month-a month and a half ago, they took all the nets out, for the first time. Ever since then, between me and my cousin, there has been one fish caught. Now, it has been really hot lately, and the fish don't want to move much, but we have had alot of rain the past few days and the temperature has dropped(normally when this happens the fishing gets real good). I have tried mainly slow moving spinners(seems ot work best)..and top water lures. I just don't know why this fish won't bite, and when they do bite, it's not big strikes(since they took them out, we have not be able to land one fish, except for one) I was told that a plastic worm might do the trick, but i have never had any success on them in the past at that particular pond. I could really use your advice. The only reason i can think of is that the algae has gotten really bad under the water(none on the surface) and the fish don't have much oxygen, i could really use some help. Can you give me advice on what lure's to use, and whats the deal with no bites or soft strikes.
