Re: Laguna Powerject Maxflo 6000 & Ecomax 9000 - problems? #41
Does anything but gravity restrain the filter pads in these boxes? If not, I'm not surprised at all that a pond pump would lift the media.

Hi all Have a pond made a few mistakes don't want to make any more.
Pond 16ft by 9.5 ft 28 fish Koi, Goldfish and 4 golden orf.
Not sure if i am feeding them enough, when fed they seem to sit waiting for more, they range from 3inch to 12 inch only have 3 biggish koi pond 4ft to 2.5 ft deep any advice welcome, all fish well happy water quality good, tests all ok


One easy way to determine how much to feed your fish is to feed only what they will eat in five minutes. I would not expect them to loose interest in that time, though, so the fact that they hang around to see if you'll feed them more doesn't necessarily mean you haven't fed them enough. If they swim way and hide as you hurl food into the pond, you're definitely overdoing it.

I'm not sure about orfe, but koi and goldfish will eat more than they can digest. As they eat more, undigested food comes out the other end. This does not make the fish grow any faster, but it will increase the load on your biofilter.

If you feed your fish 2-3 times a day, it's unlikely you're underfeeding them enough to do any harm. Overfeeding, OTOH, is extremely common, and if you really get carried away, the resulting drop in water quality can kill the fish.

hi
quilt batting i dont know what this is can you explain and also cat litter in the plants and laterite??? This is all new to me
cheers finn

As Iain said, refer to the other thread for cat litter and laterite.

Quilt batting is the insulation layer in the center of a quilt. It's quite cheap, and you should be able to buy it wherever you can buy fabric. If you use several layers, it is capable of filtering out some suspended algae (and other fines). I put six layers between the last two matala pads in my biofilter this year, and it did a great job of clearing my pond up. However, my pond was cloudy because the rain had washed in soil and I hadn't had green water yet. OTOH, I usually get some green water and so far I've had only the slightest tinge this year. Whether it's the batting or the barley pellets, I can't say, but something is working. Other people have posted about their success with using quilt batting to filter out suspended algae, though. When it gets full, you can hose it out and use it over again. Do be careful, though, it is rather fragile and will tear from it's own weight when wet.

when do u reckon i should introduce fish its been about a month now the waters been in ... but the waters stil green

Algae won't hurt the fish, but the stuff the algae is living off of might. Ammonia, nitrite, and pH are your big worries at this point. Later, you'll probably also want to test nitrate, hardness, and maybe alkalinity or phosphate, hence buying a kit with several tests can save you money in the long run. I'd stay away from the test strips, as they aren't very reliable or accurate. Liquid tests are better and still pretty cheap. Dry pellet tests are even more accurate, but they're also more expensive.

Thank you once again for your informative reply. Depending on how long this thread goes on....you will soon come to realise what a dumb dumb woman I am regarding ponds.

There's a difference between stupidity and ignorance. In your case, it's just ignorance, and fortunately, there's a cure for that. Don't feel bad if you feel a bit lost at first. Though they look as simple as an oversized bucket, ponds are actually very complex systems, and there is a great deal to learn. Everyone feels lost at some point, either near the beginning, or after they've built their first pond without doing sufficient research and things have gone horribly wrong.

The stuff in the bottom of the pond is just thick black muddy stuff that smells horrible!

That's sludge. In a closed system like a garden pond it can become a serious water quality problem, hence you'll want to do something about it.[/quote]

Last year I bought a pond vac, and unless I was using it wrong..it didn't pick anything up at all, so I decided it was a waste of money and threw it away!!

Was this something that attached to your garden hose or a rather expensive machine with an electric motor? The former type is more or less useless, while the latter actually works.

Quote:
Earlier this year I tried skimming a net along the bottom to clear some of the sludge, only to find my pond almost empty the next morning!! This happened two days running, then settled. So you can see, I dont have much success.

The water went out when you disturbed the sludge? How fast does the water go down when you leave the sludge alone?

Quote:
All of the fish have been in the pond quite some time, so I don't think they are hiding due to newness. The pond at its deepest point is about 18" and 6" at the shallowest.

That is extremely shallow. What sort of hiding places do your fish have? They might feel a bit more bold if they were never very far away from safety. Many people put flower pots or bits of PVC pipe (usually painted black to make them less visible) in their ponds to act small fortresses for the fish.

Before I drive you mad, can I just ask one last question please.....if I bought new filters for the filter box do you think that would help with the sludge problem

What sort of filter do you have now, and what media do you ahve in it? New media might help a little, but I don't think it will solve your problem. The problem is that debris (fish waste, fallen leaves, dead algae etc) sinks to the bottom of the pond and stays there. You need to first clean the pond up, and then you need to keep it clean. There are various enzyme and bacteria concoctions meant to dissolve debris so that you can remove it with water changes, but what you really need to do is get the debris out of the water before it decays. Hence a good pond vac. But a "serious" pond will be carefully designed so that any negatively buoyant debris will be pulled through the bottom drain and into the filter. In the long run, you may find that building a proper fish pond takes less effort than maintaining the one you have. This is the conclusion I have come to with my own inherited pond. (Actually, it came with the house.)

Quote:
What is confusing me more than anything is that the pond has been fine for two years, its just now I am having problems. I think the pond is probably about 6 years or more old, according to the previous owner.

My guess is that your pond was not in a steady state during those two years, but was slowly accumulating nutrients. It may not have been in very good shape when you acquired it. But it was probably the heat that pushed your ecosystem over the edge. There are many posts from UK ponders this year about unusual algae explosions and fish dying for want of oxygen. Perhaps you could have gone on for several more years without a noticeable problem, but the heat has brought all the flaws in your pond to the fore.

Re: Help! Advice needed on pump clogging up every week! #47
A skimmer pulls water from the surface of the pond, and with it positively buoyant debris. A bottom drain pulls water from the bottom, and with it negatively buoyant debris and fish waste. Ideally, a pond would have at least one of each. If you have a skimmer with a leaf basket, you might find that lining the basket with fiberglass window screen reduces your pump maintenance dramatically.

The sludge bottom is going to be a problem for your fish. You'll probably wind up getting a pond vac at some point, but in the meantime, you can use a skimmer net to get the worst of muck out. One problem with sludge is that it holds toxic gasses, and if you stir up too much of it at once, the gasses can kill you fish. Hence, you should only do a small section at a time. If it's just silt, though, you could do the whole pond. Silt resembles sand, while sludge resembles mud or pudding. If you have sludge, you could also try something like Microbe-Lift Sludgeaway. This is a concoction of bacteria and enzymes that will dissolve sludge. It will use a lot of oxygen while doing it, though, hence you don't want to try this in hot weather.

How deep is your pond? Fish sometimes cower in a shallow pond because they don't feel safe. If your fish haven't been in the pond long, give them time. New fish almost always hide for a while.

Re: new member needing help please #48
BTW, there's no reason to apologize for asking questions. That is exactly what the forum is for. Welcome, and keep asking. People tend to be busy this time of year, but if you're patient, you'll get plenty of help here.

Re: new member needing help please #49
A little algae on the walls of the pond is not a problem. It actually adds to your biofiltration, and you could easily lose your mind trying to eliminate algae completely. So yes, leave well enough alone.

I'm not sure how large fry need to be before adult goldfish won't eat them. A 1/2" goldfish would be quite a mouthful, but I don't have the experience to give you a definite answer.

Re: Help! Advice needed on pump clogging up every week! #50
Hello Chrissy. Do you have:
a bottom drain?
a skimmer?
gravel?
sludge in the pond?

Fish usually hide because they are afraid of predators. If a heron had been fishing in your pond, you'd probably have lost a few by now. But they might be hiding from a less competent predator, or they might hide because the pond is too shallow and they know they don't have anywhere to go if a predator does find them.
