Algae on Pond Sides and How To Move a Pond Successfully
August in the water garden ... reduce feeding increase water flows Probably hottest month of the year for most of my readers. You know you have a problem when you see your fish gasping for air at the water surface. As water warms up it has a reduced capacity to hold oxygen so any over feeding can seriously exacerbate the problem. If you can increase the flow through your fountain or down you waterfall this will help a bit. Slow down on feeding during these hot extremes. It's not only the fish that will suffer from oxygen deficiency because the bacteria in the filter need masses of oxygen too and especially so as water warms up.
If you have an efficient biofilter, good UV capacity and a pump that runs 24/7 you will not have any serious problems and you will be thankful that you have this equipment. If you haven't got good equipment do yourself and your pond a favour then do consider buying and the cost is low for the pleasure you get in return.
Algae on Pond Sides and How To Move a Pond Successfully
I have been asked these 2 questions question a few times recently so here's a repeat of a useful article I wrote some time last year
Algae on sides of pond is normal
Two readers on the same day posed the same question. Both were concerned about algae growing on side of the ponds. They wanted to know how to get rid of it. The answer was very simple ... you cannot get rid of it permanently; and more importantly you do not want to get rid of it either.
All garden ponds develop a growth of green algae on pond surfaces ... this includes walls, pumps, pipes, stones on bottom of pond and so on. This algae is up to 1 inch long but rarely more than that. This is NOT blanketweed or string algae. This miniature 1 inch forest of plants is a haven to natural food sources in a pond. You will notice fish "grazing" on this underwater pasture.
If you empty the pond and scrub the walls down it will soon re-appear. The query however raised another important matter. If you ever empty a pond what do you do with the fish? Let's say you have a crack or leak in a pond and you have to empty it to make repairs then it is important to plan ahead.
Moving House with fish too
Some people will arrange for their fish to be kept in someone else's pond but this can be bad for both parties and should be avoided if at all possible. Here's what you need to consider ....
- 1. Stop feeding fish one week before time to empty pond
- 2. Get as large a temporary pond on site (above ground kiddies' vinyl swimming pools could be a possibility) as you can.
- 3. Clean out the pond using pond water. 4. Arrange to buy, borrow or hire as large an air pump as you can with a mechanism for distributing the air such as air stones.
- 4. On the day you plan to empty the pond pump pond water into the temporary pond and start pumping air into the water.
- 5. Do not overfill the pond since fish when stressed tend to jump and you do not want them jumping out of the pond
- 6. If the fish are to remain in this new home for a while then make sure about 50% of the water is replaced every day with fresh water .... 2 changes of 25% are better than a single change of 50%. Remember there is no biofilter so toxic ammonia/nitrites if present will build up. This is why you stopped feeding to minimise chances of toxic build up.
- 7. Keep a close watch on the fish ... any signs of unusual behaviour then change portion of water immediately and make sure air pump is working
- 8. People with serious koi collections may well decide to have an ammonia remover like Amquel available ... just in case.
- 9. On refilling the main pond it would be a good idea to add a chlorine removing agent to the fresh tap water and in any case rather spray the water into the pond .. this will help the chlorine to evaporate
- 10. Take advantage when refilling the pond to measure your pond volume
