Hi,
BACKGROUND:
I bought a house 2 years ago with a pond in the backyard. For the past 2 years, I did not have any fish or plants. I just tried to keep the water relatively clean with chlorine (withou much success) .
But it does not matter, because ,this year, I am transitioning to a "true pond" with fish and plants.
I completely drained the water this spring, removed all the rocks and muck at the bottom in(and left the rocks out). So the pond is quite clean. I have some large rocks left on the edges.
Location : Montreal, Canada
Pond size : About 1200-1500 Gallons (As I did not build it, it's a tough call).
Setup :
- 1 in-pond skimmer + Laguna Maxflow 1900 GPH Pump + Laguna PF2100 filter with UV light + waterfall (including additionnal bio spheres)
- I also have a laguna maxflow 900 GPH pump to boost the water fall (i.e with bottom inlet , pump is in a "cage" to block large debris)
Plants: 1 water lilly, 9 water hyacinth,
Fish : 9 comets (small, 2 inches for 1 month now) and 3 Koi of 3-4 inches (for 2 days)

Water is crystal clear. I have no algae at all. (I had a bloom in May, but its gone know)
Fish / plants doing fine from what I can see.
However, I am not sure how I can correctly feed my comets. They are hiding most of the times, and never come at the surface. So no real way to tell if they really eat the food I am giving... (They are still alive after 1 month though). i feed them once every 2 days.
PROBLEM
My problem is that is started to have foam at the water surface. Not tons, but still enough to annoy me. Also, I can see that there is a layer of debris, mucks forming on the bottom and on the rocks. I am not able to get rid of it with the skimmer net. It just starts to float around everywhere, and it is too fine for the net to catch it. so it is very light / small particles, not "sludge" yet.

Not too sure where it comes from. Fish wastes, overfeeding, algeas that has been killed by my UV light maybe ?
I can leave with some muck at the bottom on the line , but the stuff on the rocks make my pond look dirty. And I have the foam. I want to improve this, and I am guessing both are strongly related.
I changed some of the water, maybe 5%. It helped with the foam only ,but it came back after 2-3 days. I am reluctant to start making large water change every couple of weeks for ecological and practical reasons. I am quite sure I have the right quantity of filtration for my pond size, and my fish load is also quite reasonable. I think.
So what is the solution to my problem ? Do I really need to buy a pond vacuum ? Anyone knows if this model would work decently to remove the
mucK? on the large rocks on the edges of the pond (but inside the water) ?

Should I rather by something MuckAway (bacterias that eats muck)? Less trouble ? Just throw it in and wait ?
Or is the problem elsewhere ?
I have already spend significant money to get the pond going, and I want to spend my money very wisely from now on, considering the pond stuff is quite expansive in general.
So your recommendations are welcomed!!
Thanks in advance.
