bio filter

I get foam once in a while. I met a guy that had a large pond and his waterfall produced a lot of foam. I didn't ask him if he had salt in it though.

ahh that would be the reason that the pond would foam...i keep forgetting that most people salt their ponds

would a gate valve work instead of a ball valve

 

[DrDave]

No, not fast enough.

 

[c2c7390]

how does a gate valve work

 

[DrDave]

Very slowly, it has acme threads and takes many turns to open. A ball valve opens instantly and provides the flush required to evacuate the sludge.

would a cone shape at the bottom of the filter help any

I am going to make a barrel filter for my future 400g pond but I had a question about the pump. Do you just drop it in the pond or do you make some kind of cover to keep the pump from clogging? Or is there a certain pump that doesn't clog as easy?

By the way this is a great site with loads of info.:biggrin:

Thanks Wolfie

Welcome aboard.

Mine are sitting on the bottom. I pull it out once a year and clean the inlet if it slows down.

Thats what I thought, I didn't know if you added any kind of screen to it to keep any leaves from clogging the intake.

depends on your pump...i use a tetra pond pump and a prepump filter(barrel style). and since the submersable pumps have more pull than push. i locate my pump close to the filter(bio), and run hose and prefilter on the bottom of pond to the far side of pond. this way, i loose less water flow thru filtration system. works great. i have two prefilters,spread out to pull water from different areas.

my pump came with a cage built around it to keep the leaves at bay.
I pull it up once and a while.

i put my pumps on the bottom...it depends on your pump...some pumps are better at passing debris than others...but basically you just need a strainer on the intake

Thanks for the replies. I kinda figured thats what most people did. Just have to wait until it warms up so I can start digging. :icon_mrgreen:
