Re: oyster shells in filter to stabilse ph #1
Thanks Violet. I buffer it up normally but it is more the holding of the Ph over a longer period of time that I am interested in and I think the more stable conditions are the better for the fish. Food for thought.I will give it a try
Thanks

oyster shells in filter to stabilse ph #2
I normally use pH buffer,however I have been led to believe that crushed oyster shells in the filter can hold the pH to 7.5.where I live rainfall keeps diluting Ph to a more acidic level.

I have some additive that looks like coral/shells that I bought a while ago and I thought I would try it .I normally buffer up at 7 pH to 7.5 but I feel it would be better not to have to so often.

Has anyone any experience of using this alternative to buffering.

Re: Re Pond Filter #3
After owning and operating both types of filter I would agree and have come to the conclusion that the normal box filters do a much better job

Re: Re Pond Filter #4
in my expericnce of having a similar filter i would say that its main advantage is the backflush system. This allows cleaning by reversing the flow through the filter,squeezing the sponges together and flushing out waste.

The sponges are usually quite small so the trapping of waste particles could be reduced and the surface area of the media is quite small.This is where your benefical bacteria colonises.Both these issues can restrict fiteration.
They are fine if you are stocked at a reasonable level,perhaps consult with the manufactuer about safe stock levels and the max pond size is 500 gal for this filter

Re: Re Pond Filter #5
Most filters have their place in the market.It all depends on the size of your pond and the fish stock levels you wish to keep.
I have had a pressureised filter myself,but I personally prefare the box filters.The surface area of the foam and media are quite restricted in the pressurised filters,but dont get me wrong, they can do a job in the right situation,they are neat and can be hidden out of site if that is your requirment

Re: Flexible (or not) hoses #6
I bought some hose that went like that,it seemed to shape to the bend ok but then went brittle but it was purchsed from a genaral garden centre. I now go to a specialist pond outlet and the hose seems a better quality with smooth plastic on the outside.

Re: Help! My pond fish keep dying. #7
I dont want to argue also,but I would like to point out that I have rang two reputable pond suppliers who stock good quality koi and sell good equiptment and have helped me when setting up and aciieve the results that I want.
The statement of facts to them was

Pond sizes
3ft x 8ft x 3ft depth = approx 2000 liters
Their response was that IF THE PERSON WHO OWNED THE POND wanted to introduce koi there is no reason not to do so as long as the filteration is to a good standard

I do agree that the pond in question is small and that it would be best put on hold any plans to introduce koi but this is proffesional advice from two sorces.

At the end of the day it the pond owners choice and I did ASK bluechild previosly if it was something he/she intended doing

no hard feelings all information is based on the success achieved with an attempt to pass this on

good luck and happy new year

Re: Help! My pond fish keep dying. #8
as I said I have a fishmate pump and the instructions this is the advice from the manufacture. I am in not in any way trying to advise bluechild to intreduce koi at present but to try and have an a filer that will cope if he does.

Re: Help! My pond fish keep dying. #9
The black box filter I mentioned stood out to me because it is the smallest one with a built in uv.It would cost ?50 to buy that uv as a separate and it is neater when fitted to the filter.You could get a smaller filter box if you wanted but that would mean an extra cut in the pipework to fit an inline uv and you would have less filer capacity for about the same price. If you bought that filter it may be an idea to connect your neptune pump to the filter then measure the water flow output then you can gauge the size of your new pump.The only addition you may want is to put a fitting to the drain plug on the bottom of the filter to make it easier to drain sediment, these cost about ?15

Re: Help! My pond fish keep dying. #10
If you are thinking of the kockney koi black box range the mega mk II seems a good choice . It is capable of filtering a koi pond of 4500 liters. It has an 11 Watt uv which should be fine as it is long and the water has longer to pass thrugh it. The minimum flow rate is 500 gal which is 2275 liter per hour. This means that if you put koi in your pond which you intend to then the total volume of your pond will be only slightly over the recomended once per hour.I know some people who circulate their water more than this with no adverse effects.I think this will give you realy good filteration

The next step up is the multibay type box filter which gradually filter through each chamber

Maybee wait for 2010 to give his thoughts on this filter

good luck
