If you are pro chemical and the pond is for swimming and occassional fishing then here are my recomendations
1. Curtine granular is for algae when it is in early growth phase attached to the bottom. Granules sink and release chemical in the bottom zone. Use a light broadcast application in the area where you can see fuzzy growth on the bottom.
2. Cutrine liquid is for floating mat algae and planktonic suspended algae. Spray over surface of the algae mats or pond surface. Liquid form takes about 10 days to 2 wks to see full affects of treatment.
3. If you have floating mats of algae first remove as much as possible with a 1/4" mesh net then treat what remains. Killing lots of algae while it is still in the pond, causes it to die, sink to the bottom and then decaying algae releases nutrients to feed the next batch of algae.
4. Aquashade - Once you get the pond the proper shade of blue, see below, (approx 1 part per million) and since your pond is small (1/9th ac), add about 1/3 cup (2 - 3 ounces) Aquashade every month. This will keep your pond the proper intensity of blue and suppress algae growth in water deeper than 3 ft. Then you basically have algae only in a narrow upper band around the edge where you can apply Curtine.
5. If you use tilapia you may not need Curtine no Aquashade or only light applications of Aquashade for a very light blue tint in the water. Try the Tilapia first. I think tilapia will be more environmentally friendly than Curtine for algae control.
6. Your Cubic feet calc is too high for your pond. Your pond is not a box 8 -10 ft deep; pond has sloping sides. For your small pond use 4.5 ft as average depth, 5025x4.5= 22,600cuft x 7.4 gal = approx 167,300 gal. So about 21 ounces of Aquashade will produce 1ppm Aquashade. First add 10 ounces. After 24-48 hrs examine the color. It may be too blue for your preference. Add portions of ramaining 11 ounces for your blue preference. However if you do not add the additional 11 ounces you will not get the full affects of Aquashade at the 1ppm concentration. Once you get it as blue as you want it add the 2 to 3 oz per month to maintain the blue intensity because over time it will fade, chemically deteriorate, evaporate and dilute with rains.
7. Aeration should not deter Cutrine treatment.
