What are these little larvae attached to the weir? About 1/4"-3/8" long. I brush them off every few days, I assume they are a good snack for the goldies.

Almost done with the deck, ran out of wood and my van is in the shop. SO I guess I have to relax this weekend!

Not sure at all what those weird looking slug things w/strange antenna's are but your deck area is looking wonderful!

After a little research I believe they are black fly larvae, which is no good because apparently they bite. Can’t say I’ve ever been bitten by anything other than a mosquito in my neighborhood. I wonder if they will be washed into the pond where the fish can eat them, or if they can escape the fast moving water when they emerge as an adult?

I’ll just keep sweeping them off the weir.

I did a little work on the pond plumbing.

I needed to put the skimmer back in because our big crepe myrtle will be shedding its leaves soon. Problem was, it was catching fish too, 3000 gph was too much. So I split the intake between a 24” long perforated 2” pipe and the skimmer. It has a very small draw now.

I also wanted to be able to control the bog flow, so I put a tee on the pump output and a ball valve that can release some pressure and create a current that will push debris toward the skimmer.

I bought a bunch of these 1-1/2” gray plastic barb fittings from the hardware store, it’s really frustrating that they don’t fit the 1-1/2” ID flex hose that’s made for ponds! I can force the fitting in about 3/8” but that’s not enough to keep it from slipping out. The 1-1/4” fittings are of course too small. GRRR.

Have you tried heating the hose up by running under hot water or other heat source? Works for some types by softening or expanding it enough to slip over the fitting. I have never tried it on hose that large before though.

Good tip, I hit it with the heat gun and it did help a little.

Deck is DONE, it's connected to the pond so I figure it's relevant to the forum, right? I think it's pretty snazzy if I do say so myself.

The deck is really my outdoor workshop, machines can roll out from the adjacent shed.

Oh, and I think my bog is plugged up, if I divert the full flow through it the water will overflow. This probably means that the water doesn't flow through the gravel but rather over the top. The crepe myrtle dropped a lot of flowers so I think those got sucked up. I am going to pull everything out and make more holes in the diffuser pipes, maybe give the gravel a rinse.

The bog was indeed clogged. It got to where I couldn’t run the water at more than 25% without it bubbling over the top. In retrospect I should have built the bog much deeper but the proportions wouldn’t have looked quite right to my eyes.

There was about 1” of thick, heavy sludge on the bottom, some of which was probably sediment from gravel and potting soil/clay. Roots of creeping jenny had formed a solid mass in one corner about 10” square. Removed all plants and gravel and did the following to remedy:

-replaced bog liner (I had trimmed it too small on first install so water leaked over the top)
-rinsed gravel
-cut more grooves in diffuser pipe to reduce points of high pressure that might lead to channeling
-removed a lot of creeping jenny...yikes that stuff is prolific

lol my bog was over run with water mint. I let it really go this time of year since the bees love the nectar from the flowers in the fall.
