Thanks for explaining.
How long does it usually take for the water to become crystal clear?
Also since I don't have a skimmer should I be netting out any fallen leaves etc or will it be ok to simply sink to the bottom over time?
I've done a water test and I have 0 nitrates in the pond.
People say adding plants starves the algae of nitrates so you don't have green water.
Can someone explain to me them how my water is green and I can't see very deep now even though my nitrates are 0?
Since putting in those gold fish a new potential problem has come to light.
Due to the shape of the pond there is some quite large folds which aren't getting pushed back by the force of the water. They are hiding in that fold.
Could this cause any problems for larger fish or will they be ok?
Yeah I think what I already have does exactly that it basically uses air to create an airlift pump and pushes out the air and the water on the surface of the water and creates a good flow.
I've went out today and bought 20 canary goldfish for the pond so that the plants get the nutrients they...
When I see them colour up I'll put them in a sort of basket on the top of the tank with holes in the bottom so the eggs fall through.
I have an air pump pushing 10lpm through a small filter which causes a good flow.
What kind of power head do you recommend?
I can't find many sellers of decent cold water fish here. All fish stores seem to sell basic goldfish, koi or exotic fish for indoor tanks.
I have 5 rainbow shiners in a 100l aquarium atm heated to 25c hoping they start breeding but at the moment they havnt even coloured up yet.
I can't find...
They look great.
Yeah I calculated the actual flow rate to be around 30,000 lph including the factors such as head and pipe although one thing I was not sure on for head hight so you calculate head above water surface or head above the pump?
I always thought it would be from the water surface...
It's just two 18,000 lph pumps side by side pumping the water to the bottom of my bog.
Do you think those rates of turnover are too much?
It's just two of these pond pumps:
Well I wanted colourful minnows so the ones I have are actually rainbow shiners - not technically a minnow but very similar. They cost 7 pounds each in uk money but I've just been looking for a simple minnow supplier and it's still 2 pound each and I reckon I'd need a lot more than 10 minnows to...
Well in nature all fish are the prey of another. A natural pond will always have some fish becoming prey unfortunately.
Yeah from research I've done trout are perfectly fine in ponds. I have a 9000l pond it's more long than wide and a waterfall with a bog filter at the end.
I have 35000 lph...
I want to get the golden variety of rainbow trout. Along with some minnows as potential food for the trout. Minnows will have plenty of hiding places amongst the underwater plants and the shelf.
I may have to try and find a very cheap fish that I can just add for now and hope they die out...
Thanks for all the replies the reason there is no fish in there at the moment is because I simply can't buy the ones I want until November the only stockist I can find nearby is now out of stock until then. I was too late in finishing my pond by a couple of days and he ran out.
The water as...
pond is finally finished and I have had the bog filter/ waterfall running for around 2 weeks now.
At first the water was crystal clear i could see 1.2m down with ease.
Now it's starting to turn green with algae and I havnt even put any fish in yet.
I know my bog filter doesn't have many...
Yeah all the plants are hardy to my zone.
Is there any type of fertiliser I can just put straight into the water?
Some of the pots I've put really deep I don't want to have to go for a swim to get them
