Green stuff

[Limu]

Hi,

So I have installed a pump and a filter and it has done good as you recommend but does anyone know the green stuff that is growing. I have added photos. Plus how do I kill it, we are in spring now and summer should be here soon.

Thanks

That looks like the good algae that we like to grow on our liners and rocks underwater. Keep it and don't get rid of it as it is carpet algae. Carpet algae covering the rocks or liner in your pond is actually good and shows you are in balance. The fish will like to nibble on it too.
