Extreme hard water= solutions??

[justdoit]

As states in the title, have a good friend with extreme hard water. This is a large pond and tests this way out of the well supply. Sending off for complete water analysis but wondering if there is anyone with ideas. Looking forward to any suggestions. Pond will house koi & plants. Volume is approx. 18,000 gallons !!
thanks in advance. V

O yea, Believe he stated his PH is running 8.7 when tested morning & evening. Pond is relatively new w/ waterfall, long planted bog/stream & 2 large aerators. Water lilies are in but just coming out. Pond was seeded for start up bacteria ( forgot name). Runs a UV sterilizer & skimmer. Goes from crystal clear to extreme hair algae in matter of a couple hours but may only happen once them be clear again for a week / 10 days.

Contact haw I think they have some leaves that will naturally lower PH

I believe his name here is Rama he had an awsome koi pond saw it at the htpc meeting awhile back he might be able to help

[justdoit]

Will do that. Thanks to you both. :)

Best way to lower ph and all that is to move.

Water softener. IAL (Indian Almond Leaves) is what Cuong is referring to. Alder cones also work, but it's a large pond, you'll need a lot of leaves and cones to soften the water from that high of a pH. A water softener would be the better choice.

water softener won't lower the PH that much I have one and it doesn't really lower the PH very much.

This will help with the algea.

Algae Control in Ponds With Barley Bales: On-site Results Dow AgroSciences - January 29, 2001 Algae growth during the summer season in ponds can pose several problems. The algae that grow in ponds used for irrigation can clog pumps, block filters, cause odor problems, and is generally considered to be aesthetically unacceptable. The proliferation of algae appears to be closely associated with the level of nutrients, especially phosphorous, in the water. High nutrient levels are often found in ponds and lakes associated with parks, golf courses, housing complexes and industrial sites. Conventional control of algae can be either mechanical or chemical. Both methods can be expensive and inefficient. Depending on the pesticide used, chemical control may limit irrigation use or harm non-target aquatic plants and fish. In some instances the algae problem may increase over time if competitive plants and algae-feeding fish are decreased. Barley straw has been suggested for use in ponds for algae control, yet minimal replicated scientific research exists to substantiate the observed positive results. It is believed that the barley, as it decomposes, slowly releases hydrogen peroxide into the water at levels that are toxic to algae. The Center for Aquatic Plant Management in the United Kingdom has the most active efforts in the development of this method of algae control. Following is a brief summary of their observations: This method will not kill algae already present; the bales must be in place prior to algae bloom. The algae are suppressed best when the straw is decomposing in a well-oxygenated environment. How much straw is needed depends on the surface area of the pond. Pond depth or volume does not appear to influence suppression. One-half to 1.5 oz of barley straw per 10 square feet of surface area (approximately 2-3 bales per acre) will provide good activity against the algae. Higher rates have been shown to provide better algae control if the problem is severe. Too much straw can deoxygenate the water. It is best if the straw is applied loosely so that water can move freely through it. A cage or netting can contain the loose barley. The barley works best when it is at or near the pond surface. It is better to use multiple "barley stations." Apply the straw in the fall or early spring; this will give the straw a chance to rot and get ahead of the spring/summer algae blooms. Water temperature will affect how quickly the bales will begin suppression. At temperatures below 50 F, 6-8 weeks are required, at 70°F, 1-2 weeks are sufficient. Once active, the straw will remain effective for approximately six months. No negative side effects have been reported; however, increased invertebrate populations and improvement of gill development in fish from ponds where barley straw was applied have been observed. On-site Results In 1998 six golf course superintendents in Nebraska used barley bales to evaluate their effectiveness in suppressing algae populations. Following is a brief summary of their observed results: Fremont Golf Club - Mick Reifert, CGCS, Superintendent. Four compressed bales in driving range netting put on frozen pond surface with cinder blocks to "sink" bales. Bales floated and moved freely around pond. Quote: "I would show you the algae but there isn't any." His biggest concern is where to get bales next year. Lochland Country Club, Hastings, NE - Craig Ferguson, CGCS, Superintendent. Compressed bales installed after significant algae bloom. No positive results. He will use conventional means next year (aerate and copper sulfate). Meadowlark Hills Golf Course, Kearney, NE - John Beideck, CGCS, Superintendent. Nine compressed bales on three surface acres. Reasonable/acceptable results. Applied in early spring, prior to bloom. Excellent results on a smaller pond. He will use barley bales again next year, if available. Indian Creek Golf Course, Elkhorn, NE - Lon Camp, CGCS, Superintendent. Applied six compressed bales/surface acre in early spring along edge of pond when water was down. Previous year, algae problem was "disgraceful." In 1998 no algae was evident. He will use barley bales again, if available. Grand Island Municipal Golf Course - John Hadwick, CGCS, Superintendent. Applied two barley bales to a "no turnover pond" of approximately 1/3 of an acre in early spring. Pond has a small aerator. Control was substantially better than ponds treated with copper sulfate. Will use barley bales again, if available. Country Club of Lincoln - Charlie Hadwick, Superintendent. Late installation, with results comparable to Lochland Country Club. Possibly will try again next year.

Some good info here on high PH. http://forums2.gardenweb.com/forums/...293322532.html

True, but it sure beats buying like 200 leaves and cones.

I guess it depends on how much the cones cost.

[cu0ngsayz]

Yea. Water softener don't do much. I test water ffrom the tap and water from the softener not much of a diff

[justdoit]

Have shared the suggestions w/ my friend. Found out the barley bales may be the trick for softening water & stabilizing PH With such a huge pond 18,000g, cost effectiveness can be an issue. :)
thanks for all the input. Will let you know the outcome.
