Overflowing filter
Posted: Mon May 16, 2011 9:08 am
Hello All - my first post, please be gentle. I have done a search but nothing came up so if there is thread please point me in the right direction.
A little history to set the scene...
I've been around fish for most of my life - ponds and aquariums etc. Never had a great problem other than an odd case of white spot in the tank so apart from reading books over the years not really up to date on the latest methods/trends etc.
Now to my problem, My pond is approx 4500 gallons, I inherited my koi and goldfish, 9 years ago along with the filter system - [cold water tank, pump fed, over brushes, sponge matting and alphagrog, X 2 outlet gravity return]. All worked well for the first 7 years I've had it set up, until 2 years ago when it started to over flow on occasions - mainly in the springtime. At that time I sprung a leak in the inflow pipe and repaired it by installing a ball valve - killing 2 birds with one stone so to speak as it enabled me to reduce the inflow slightly. I have back flushed it on numerous occasions and tho' I did get some sediment out it only sorts the problem for a couple of weeks. I'm wondering if the pipes have sunk causing a low spot?
However it is now starting to do my head in and my OH is about to retire so I want a system I can depend on so we can go away without having to worry about it whilst family take care of feeding etc. but I don't want them to have the bother of sorting out an unreliable filter system. The pipes are buried [unfortunately] so come August when hubby is home the whole lot is coming out so I can get it sorted.
Reading various articles there are numerous 'new to me', systems on the market and I was wondering what recommendations you have [I understand the different systems, just not what would be best for me] - bearing in mind of course we all differ in thought and spare time. I love my fish and pond and don't mind spending time on it but don't want it to take over now another chapter is opening.
Any thoughts, opinions welcome and I'm a bit of a diy'er don't mind building my own system rather than something off the shelf.
