We've made a pond out of a small spa lined with pond plastic it's around 1000lt. The pond has no outlet so we siphon off and replace water.... I've been using the pond conditioner called Microbial algae clear. The water is quite green there is no algae but it seems murkier each week. The fish are happy, not looking for air and feeding well

So do we have a problem or is green water normal.

The green water is algae 

Green pond water is caused by tiny floating algae, which grow explosively. Additional effects are low CH value, high pH value and stagnation in growth of oxygen producing plants. Green pond water frequently occurs in newly built ponds containing water rich in food.
