With a quote like that it is easy to see the 'mad as a cut snake' attitude saying XXXX is a beer is swearing in this state and just about every other state apart from the 'cut snake' state. Now as far as cartons V slabs go Slabs are box's of REAL BEER ( Coopers) and cartons are the box's we put the body parts of XXXX drinkers in so they can be shipped back to 'cut snake' country and not infect our southern soil...... |

I thought XXXX was only because Queenslanders could not spell B E E R, so they had to label it in the states language. I have drank many beers around the world, and still rate XXXX as one of the worst beers as a close second to Fosters. In all fairness most beers have changed over time to better suit the consumer palate, what was once bitter has become sweeter, and vise versa. Personally XXXX always gave me diarrhea the following day, where no other beer would. So hence my thoughts its a Sh%! beer. Pete. Sometimes it just works |

Norcold, With looking into Alum batteries i realized the Potassium alum crystal is used in the basic, all green, natural, unscented, crystal deodorant you buy at the supermarket. Also used in many food products and even as blood coagulant for use on shaving cuts etc. So it could be worth tossing a few crystal deodorant sticks into the dam. Although i would try one in a bucket or tank first, and would expect it to work as a slow release due to the solid crystal form. Potassium alum is not harmful to you (except for high quantities, like anything else) and even adds a sweetish taste to the water, so no real harm in trying it. Pete. Sometimes it just works |

When I was a kid, we would visit my cousins at Narromine NSW and their tap water was the only water I had ever had that would fizz like soda water directly from the tap. The town now filters the river water instead and is much more drinkable. I guess water quality varies greatly from place to place and one makes do with what one has. |

Pot Al I`ll keep in mind but I`ll fart around with EC first, be awhile but am currently trying to catch a fish. Sort of trying to stay away from a chemical solution, but if nothing else works! We come from the land downunder. Vic |

Have you not caught that fish yet?? The funny part about that is regardless of what method you use its still using a chemical reaction of one form or another, weather you add the raw chemical or produce the chemical electrically

My understanding of EC using iron electrodes is the process is achieved by ionisation, but if it is not so the small amount of chemicals produced (if it achieves) will be immaterial. Plus it does not seem to be a settled science. But hey I`ll try whatever. I`m a lazy fisherman and only spend the cool part of the day fishing, tis more of a religion chasing barra not really about getting a feed. Bit like recreation gold prospecting.

If you clarify your water there is a good chance you will trigger a massive algal bloom due to the suns energy penetrating deeper into the dams water layers. The water surface will need some % of protection from the sun. perhaps you could build a magnetic resonance ioniser like the Hydrosmart then fling a few handful's of bentonite across the waters surface to form a gel layer on the dams bottom and trap some of the minerals. Something like a radial flow filter will remove a remarkable amount of solids from the water column and there are no moving parts BUT they will produce sulphuric acid if the sludge is left to sit in the filter bottom. I'm confused, no wait... maybe I'm not... |

The chance of an algal bloom is the chief reason I wish to only treat the water being pumped. Dam being shallow but large in area in our climate, algae is a massive problem Thus a small EC unit on the suction of the pump, is the way I`m thinking, with perhaps a small "pre cleaner" incorporated as Glenn suggested ie. not to treat the whole dam. The hydrosmart works I have an acquaintance who has one, but my understanding of that system is it requires more power then I am considering, but should a small EC unit not work, I`ll trial magnetic ionising. Have tried using permanent magnets attached around the suction pipe(PVC) with like poles facing inwards even, but no success. Talking about bentonite, a few years back I was treating a dam with bentonite to stop the wall leaking. In its dry form it is very fine even finer then dry cement, thus you end up with bentonite dust in your clothes. When the missus washed the clothes in the washing machine, the lint filter was completely blocked up with the bentonite, so blocked up you could fill it with water and it would not leak through the filter. Amazing stuff, expands 15 or so times when wet. But whatever, I`ll trial not just to achieve clean water but also for interests sake, thus all suggestions are welcome. Sometimes solutions for small problems like this are found thinking "outside the square", with a solution that lies inside the KISS principle. We come from the land downunder. Vic |

I mainly disagree with Yahoo, as if you get the balance right the pond will take care of itself, water needs to be seen as a living matter and if you get it in check mother nature will take care of the rest. If you have ever owned a swimming pool you would know if the water chemistry balance is correct you will have crystal clear water that is healthy. Its not hard to get the water mass in balance, and adding bentonite will do diddly squat to the present problem, in actual fact there is enough clay solids in the present water to achieve what adding bentonite would do anyway. Bentonite is just a high yield powered clay, why add clay to a water source that has a problem of suspended clay particles to start with. The whole point you all are missing is to address why the dam is a murky duck pond to start with, it is totally out of balance and mother nature needs a helping hand to correct it, best to drop the suspended particles of the pond to the floor, so at the very least you clear the water and form a filter cake on the dam floor from the sludge. Now you have about 80%+ clean water, with the solids forming its own micro environment on the pond floor (mother nature). Once the solids are gone there is room for much more oxygen to be adsorbed into the water also helping to create a micro environment. If the water PH is to extreme to one side of the scale, as it might well be due to the chemical adjustment to flocculation of the pond, then it needs to be adjusted to around Ph neutral (Ph7.0), once the pond is now in balance mother nature will take over and attempt to keep it clean for you, she might need a hand out from time to time, but it will give you years of service for little input once the micro environment is established and working. Why do down line filtering when mother nature can do it far better if you give her a hand to get started. There is most likely a ton or two of solid particles suspended in your pond, do you really want to deal with that down stream, post pump? Best to drop it out to the pond floor and then work with whats left, like dissolved salts, perhaps calcium salts that was commented to block drippers, much easier to deal with the smaller problems.

While on the matter of algal blooms in ponds. If you have a fish pond that has algae problems, place a few handfuls of Barley stalks (not the heads) tied in a bunch with string into the pond water, it will not effect the fish or any plant growth, but will eliminate any algae growth. Perhaps not practical for Norcold with his duck pond. Pete. Sometimes it just works |

Mother nature will solve my dams problem in time. It is only a new dam 6 years or so old in original build, last year, made it 5 times larger. I`m going to do squat to help her, she doesn`t need help just time. In the meantime I`ll try to filter out the clays in only what I use. Depth would help but unfortunately the floor is solid conglomerate ( flat like a billard table for 100`s maybe 1000`s of hectares), thus I cannot deepen. Unless I break through the conglomerate (approx. 12" thick) then I would have no water. The conglomerates base extends right into the surrounding hills where it runs the water down into the dam. A fairly unique source of water in a very dry part of country. Depth would lower the temperature of the water, thus lessen the chance of algae problems. The wild ducks love it, as does all the local wildlife. It has turned my "desert" into an oasis. In years I`ll report back on just what Mother Nature achieves, I suspect and hope it will turn into a wildlife haven and a clean water supply. Of perhaps further interest, a shallow well was built 100metres away probably about 130 years ago, the water was used by the steam trains, a privately owned line then that served the local large (mainly tin)mining district of that era. The extensive farming concerns in this area rely on irrigation channels from the Tinaroo Dam on the Barron River 100k`s away. Without that water this area would be a dry arid area, except for the small springs that are fed by the hills accumulation of water during our wet (30"annual average) such as the one my dam uses. I can easily access that water (would be very much cheaper) but I wish to be independent. Also perhaps of interest, most of the bentonite used in Oz is imported from India. It is cheaper than the plentiful supplies we have in OZ, apparently the cost of the "Green" tape makes mining ours much dearer. Duct tape will hold up nearly anything, green tape will hold up everything. We come from the land downunder. Vic |

Update- Pete, Have taken advantage of the dry and pumped dam out, currently removing clay and once full again get back to electrocoagulation trials. Hopefully will get some gentle rain and repump out a few times.
