I am forever asking questions here so I figured it was time to give something back . So here are some pics of the pond and the fish
I originally started with three fry last summer. We then got 6 more fish from an LFS (2 shubunkin, 2 red comets, 2 yellow comets). One of the (yellow?) comets died so we got another one a while back. One of the fry turned orange last year but then almost reverted to black again before the winter. It is now orange and I can't distinguish him from the shop fish anymore
Here is a selection of the fish all hanging around together. The brown fish is one of the fry that survived last summer and started my pond hobby off (see my profile for more info on that story!). The white one was a yellow comet, so much for the yellow!
Here is another snap of some of the fish. I had three fry last year, two of which still haven't changed colour. You can see both of them here, but it does show just how hard it is to see these fish on a normal day.
This is an end on shot of half of the pond. It looks tiny like this! You can see the two lilies, and an Arum lily. You can also see the return from the filter into the pond. The return is split into two with a Y-piece, some water pouring into the pond to help aerate it, the rest just gushes into the pond below the surface.
And last but not least, the first lily flower this year...
Thanks to everyone for their help, the pond would definitely not look so nice and the fish so healthy without your help!
I've been looking at ways to aerate my pond recently because of the hot weather. I have only had pond fish for almost a year now, so please don't consider me an expert
Firstly I would say filtration is a must for your pond.
And as for oxygen levels: There seems to be three ways to aerate the pond, 1) An air pump. A good to have on hot days I guess but the good ones seem very expensive to buy and run. Also, I couldn't find any for love nor money at various local shops last weekend, lots of people buying them in this weather I guess.
2) Water movement. A fountain or waterfall helps as the water movement helps mix oxygen into the water, and the moving surface of the pond helps too.
3) Plants. This is obviously natures way of doing things, but from what I understand it only really works in the day (and better with in sunlight). At night some (all?) of those oxygenating plants are actually sucking up oxygen out of the pond. If your fish seem to be struggling at night or first thing in the morning it might suggest "dawn depletion".
I have still not managed to make a waterfall for my pond. My pond is filtered, and the return water is simply poured back into the pond. This makes a small splash but could be much more effective if I could find a decent spray attachment for the pipe.
My fish don't seem to be struggling at all, but I do have a lot of greenery in the pond right now so I have bought a little fountain that I turn on over night to try and keep the aeration up.
I know your question isn't just about aeration, but I figured I could share what I have been sorting out over the last few weeks
I've never looked at muscles for my pond before, but took an interest after your post and did some searching.
They do seem to be good filters but my small 800l pond is really well filtered by pump/filter kit so I wonder if the muscle would actually find enough in the water to feed on.
From what I have read they will happily move themselves around on the base of the pond. I don't know if they will be able to climb up a steep slope back to your ledge, or even if they would want to try.
I would not add too many more fish to the pond right now, as your mature fish will soon produce fry which will hopefully survive if you keep the water quality good, and you will soon be over run with fish
If you can work out the volume of the pond, or tell us how wide and deep it is, it will help you to make sure that you have a pump and filter that is up to the job. As Fishy-Fishy says, the volume will also help you decide on how many and what type of fish to keep in there.
I've only had a pond for less than a year, but my Oase Filtoclear set that included the pump, filter and UV ( click here ) has kept the water quality very high and crystal clear since I first got it last August.
Firstly, do you know what filter and pump you have? They may be good enough. The filter will remove all the debris and fish waste, but will not keep the water crystal clear by itself. A UV filter will help clear the green water, and may be all that you need to add to your current setup.
There are tools down the left hand side of this web page that will help you work out the volume of your pond. It is almost 9,000 litres, ~1,980 (UK) Gallons.
There is a huge range of makes and types of filters, and I am not expert enough to give you much help choosing. I can only say that I installed a Oase Filtoclear Set (e.g. click here ) which has a built in UV and it works a treat. The bonus with my Oase filter is that it is a doddle to clean.
I woke up this morning to find the pond with only 1/3 of its normal water, and all because there was a very small leak in the pipe that feeds the water from the filter back into the pond. This was an actual tiny hole in the pipe, not a leaking joint. My only guess right now is that some animal or other either walked over it, chewed it or did something to weaken it.
I only had time this morning to turn off the pump and elevate the leaking pipe so that it doesnt continue to drain water away, and plan to replace the pipe tonight after work.
I think I was lucky this time, the leak was tiny so it didn't completely drain the pond overnight. Any ideas how I can try and stop this from happening again, or to stop the effects being potentially so drastic?
One idea is to raise the pump up enough so that it will not be able to pump ?a few? inches of water so that the there will at least be some water in there that the pump cant remove. The pond isnt that deep though, (2.5/3 ft?), and I wonder if this would leave a layer of bad water at the bottom of the pond? And how little water can keep the fish alive in an emergency?
Another idea is some kind of water level monitored cut off device that stops the pump if the level drops too far.
I've just bought some plants for the pond, and wonder if I should quarantine them first. I have an old bath tub outside that is full of water, which should make an ideal quarantine pond.
I am guessing that it is a good idea to quarantine plants, but what would I be looking for during the quarantine period and how long should it be? There are some very good articles on this site about quarantining but they all talk about fish and barely mention plants.
Also, some of the plants are dry packed (they are a kit with a tub, aquatic compost+clay, gravel and bulbs). Should these also be quarantined considering they have probably never seen water before?
I would love to light up the pond enough to rival an airport runway, or a Christmas tree
I am always sorely tempted to get some form of lighting for my pond, but there is such a big choice and they are such a high price that it always puts me off. Solar, LEDs, color changing, floating, there are loads to consider.
There also those lit up mist makers, but they might be bad for the fish? Does anyone know?
I also wonder just what effect the lighting has on the fish during the evening, they certainly get spooked by my security light at nights.
I was sort of joking about the Christmas Tree look, but even simple lighting can have a dramatic affect on water
