    I purchased an extreme bio filter for the school pond, I can size the pump, but what do I need on the suction side of the pump? This will be a non submersible. I am thinking perferated pipe. I do have the waterfall for areation, but I am novice.

    Perforated pipe? I believe most folks here use flex pvc or schedule 40 pvc pipe for their plumbing. We use both in many sizes and find it to be quite durable. Good luck, @Kevin Koloff! Here's a view of both materials.... image.jpg image.jpg

    I'm talking about the inlet in the pond, not the external piping.

    Need to know the size of the pump and the recommended piping size.

    Thanks. This system I am putting together. I do have the filter, next is pump, then piping. I had thought of perferated pipe in the pond (suction line) as to pull water in a larger area than on the end as the basket with open ended pipe is.

    Can be done, but may be harder to keep clean and unclogged.

    Thats a good point I didn't think of! My plan was to hard pipe both suction/discharge with perferated suction pipe in the pond water, now I am thinking flex with the strainer (suction side).

    Think of it this way: If a perforated intake pipe was an overall workable idea, somebody would have them for sale.
    If you are going to utilize perforated pipe at the discharge,be sure that you do not create too much back pressure on the pump. Although some is good, too much will drastically shorten the pump's life.

    No. On the discharge side I will increase it to 2". I will control the pressure to the filter vessel with a valve at the suction side of the pump.

    Placing a valve on the intake side of the pump is not advised. This can quickly cause overheatiing and premature pump failure. Control valves should always be on the outflow side of a pump.

    What the valve will do is act as a bypass. It will be pressure control, and bypass water back to the pond. Holding off on it now, as i need $, but also I have several new fish!

    Previous advice still stands.

    You know, I think I will take your advice. Place the pressure contol at the discharge side of the pump, and back to the pond.

    Well, I have new fish. Looks like 6 and (now) about 1" long. Today they (new ones) came to the top with the rest, but didn't feed. I will try them with flakes later this week, along with the other food.
