Hi all. I have spent a few days reading all your knowledge and i am happy to say i am going to bite the bullet with aeration. I have a small pond located in south houston texas area. pond is 9,500 ft^2 with a small 1,700 ft^2 island in the middle. I am figuring 7,200 ft^2 surface area. I am not sure of gallons maybe some one can help with that but pond is around 5-6' average with about 10% at 10' and most under 5'. I am weighing out either the Big Max kit for 388$ with the two diffuser rings or building my own kit. I am looking at the GAST 82R pumps or the thomas 2660.

If i build my own i will switch diffusers to the membrane 9'' discs. I have read to put the diffusers close together and have also read to put them away from each other. Will either of these systems suffice and what about diffuser placement. I would like to put one at deep end and one around the other side of the island but i am ok with both at the deep end. Any input would be greatly appreciated.

BTW i have been attacked by duck weed and copper sulphate kills have prolly ruined my water quality. Pond is about 20 years old and only aeration i have had is a sump pump churning water in one end that died this year. So i assume i will need to gradually move into aeration little by little. Thanks in advance.. happy ponding.
