Good news and Bad news on the Crescent Pond project.
-June'22, Tested pH and it came to 7.0 pH
-July'22, Tested pH it came in at 7.0 pH
-July '22, Stocked 15# of Fathead minnows(FHM) and 40 Redear Sunfish(RES)
-Aug'22, Tested Alkalinity - Hellaoff at 23ppm... < 20ppm fish can't live.
With the pH dialed in I needed to get Alkalinity ppm up above 50, really above 100 ppm if possible. I looked around and found powered gypsum was the just the ticket I needed. Did the math on surface arce foot etc ordered enough to bring, in a lab environment, the Alkalinity up to 150ppm, the lower limit the pros at PondBoss told was 80. IF I get it to 100 ppm I'll be real happy.
-Aug'22, amended with 6000# of ultrafine gypsum to meet the 150ppm of Alkalinity. Did this off the venerable old rowboat with a modified sluice and 4.0GPM pump.
pH and Alkalinity 'should be good' for bit but now the seep.
With the drought this fall I was really hopeful the water drop was the result of that and not a seep. That's not the case as Oct-Jan rolled in with ample moisture and almost no evaporation (PAN) the level is holding solid about 2' below the overflow.
That's the good and bad news, if I don't do another thing the pond will thrive. .... but I'm me and as I push the glasses up the bridge of my nose and adjust my britches I know I 'might' be able to plug the seep, it raised up the overflow once so somewhere there's a seep (maybe more) but since it reached the overflow it's put a couple hundred thousand gallons thru the seep - it shouldn't be too hard to find.
Current plan is to test pH and Alkalinity in March'23 - if those are holding steady I'll stock FHM RES and Golden Shiners(GSH) Smallmouth Bass (SMB) and Yellow Perch(YP) - to be in the right ratio and plentiful. Also plan to add 300-400 crayfish.
Also in March'23 I'll do a real solid visual inspection of the entire pond perimeter to locate the active seep(s). My bentonite supplier has both the granular and chips and the current advice from the pros is 70/30 Chips/Granular, 6" thick and 8' in diameter from the seep. I figure I'll chase the seep for a year or two, do the bentonite cap a few times and see how it works... I do not plan to chase it until I fix it but this is my
-Apr'23 20 bags of chips and 6 bags of granular per located seep
-Apr'23 replace 12-15 cypress tress that didn't catch from last Apr
