Kan ek dalk by julle inligting kry oor Koidam filtersisteem?
Ek het ‘n koidammetjie by my huis gebou (6m lank, 1m wyd en 600cm diep). Ek het ‘n swembad pomp opgesit met ‘n 500L (daai wat regop staan met die rubber bobbeltjies in) waterfilter. Die water bly groen. Ek kan die water uittap, die dam skoonmaak en nuwe water intap, maar die volgende dag is dit weer groen, mens sien nie eers die visse nie. Ek het tans 3 koi’s in die water wat ook nie wil mak word nie. Ek gee elke dag op dieselfde tyd vir hulle kos en gesels met hulle as ek by die dam kom.
Kan julle my dalk raad gee om die dam skoon te hou en hoe om hulle mak te kry sodat hulle darem gesien kan word.

Jy bedoel seker jy het 'n 50 liter filter en nie 'n 500 liter filter nie. Jou pond is slegs 3600 liter groot.
Dit klink vir my asof jy te veel water changes doen. Elke keer wanneer jy water changes doen, verleng jy net die tydperk wat dit neem om die pond te mature.
Is jou UV light groot genoeg? Werk hy? Met jou specs behoort jou groen water probleem gou opgelos te wees, deur net te wag en nie te veel water changes te doen nie. Moet nooit meer as 30% nuwe water insit nie. Jy haal die goeie bakterie uit en gee nuwe kos vir die alge.
Sit 'n paar plante in.

Hier is my artikel onder "water conditions" wat jou vraag aanspreek:
The other reason for green water (which is linked to the above) is because of the absence of enough bacteria, especially directly after winter, because the bacteria takes a while to grow after the winter months, as it requires enough heat to grow. New ponds always go threw a phase of green water, despite the presence of a UV light. This is nature's way of sorting out a balance. Don't interfere unnecessarily.
An affective UV light will clear most of the floating algae which makes your water green. However, it is not effective against blanket weed, the hardy type of algae on the sides and bottom, but these does not affect the colour of the water and can be removed manually if required. One have to remember that the tube is only really effective for a period of one year. So, if you have green water despite the presence of a UV light, a replacement of the tube or an additional light might be an option. It takes a few days to clear the water. When you buy a UV light, always buy a bit bigger than what u actually require. There is not a big difference in the price of a 15-watt and 30-watt UV light. The one is approximately R 550.00 and the other one is R 620.00. We install 30 watt UV lights in ponds of 12 000 litres, although the manufactures indicate that they are good enough for 30 000 litres.
Die koi sal ook sommer makker word wanneer die water helder raak. Hulle raak meer gewoond aan beweging en mense en met die groen water nie. Sien ook elders op die forum hoe om koi mak te maak.
