Will you look at that picture?
Isn’t that swirl of color amazing?
Usually, this many koi in a pond ends up in disaster. The fish produce too much waste and ammonia and nitrate levels in the water become too high.
Ammonia is the most significant dissolved waste in koi ponds. It is produced by fish wastes, rotting leftover food, and decomposing plant matter. The bacteria that exist in the biofilter convert ammonia first into nitrite and then into nitrate.
While ammonia and nitrite are highly toxic to fish, nitrate is much less so. However, as nitrate accumulates, fish will eventually be affected.
This is why we recommend placing an oversized filter on the pond, and vacuum out sediment on the bottom quite often.
Most people don’t want to spend the extra money on a filter. They would rather spend it on more fish! Yeah, we get it, but that is another reason we recommend a larger filter. People always add more fish then they should to a pond and then overfeed them.
Our filters are made to hold more biofilter to convert ammonia to the less harmful nitrate. This is important as ammonia and nitrite can kill koi fast. So having extra filter material to hold useful bacteria that break down these killers is important.
Our recommendation to clean the bottom removes dead plant material, wasted food, and sediment that contains the nitrates. So first waste that converts to ammonia and nitrite are removed then the less dangerous but still toxic nitrate is also removed.
We understand this is a pain to do frequently, but a clean pond makes for healthier fish.
Isn’t that what we all want?
As I have mentioned before in other posts, we do maintenance on many ponds. We have seen some crazy things. But nothing matches this for koi feeding. Those fish are eating koi pellets soaked in a solution of water and legal hormone alternatives. What are hormone alternatives? Read more here: crazybulk-reviews.net, they are the same things that bodybuilders use to bulk up. Crazy Bulk Reviews says that ingredients are amino acids and such.
The owner dissolves the pills in water, adds some fish oil, and soaks the pellets in the solution until they absorb the liquid. He then dries out the mass, crumbles it up and feeds his koi with it once a week. He says that they grow faster and are more active than before he tried it.
We don’t recommend this, but the fish are healthy and as you can see from the photo very active.
I think it is the water changes, extra volume filter and clean pond that makes the fish the way they are.
But the customer is always right! As long as the fish are healthy that is!
