Topic: How much flow is TO MUCH? Posted: September 09 2004 at 9:36pm |
I have an external pump that I got for free that has no GPH rating on it. I plug it in and it shoots a garden hose sized stream probably 2-3 feet. I was thinking of hooking it to my 120 with 2 outputs, But I am afraid it would blast everything out of the tank. I put an older powerhead in my SW 80 and it blasted stuff off the rock just about. I pulled it and went back to my 802 and it was all better.

I will just give my warning that your system will flood, bulbs will burn out, and things will take continuous maintenance... get over it.

I had a similar problem with my external. I put a ball valve on the return line to regulate the flow. Got some free plumbing stuff if you want...Still owe you.

I've never seen a tank with too much circulation.

You can always split the number of returns with y's and or t's from a plumbing supply.

You know that you have too much flow when the overflow can't handle it and it starts overflowing!
I was over at Kam's house (awesome setup!) last night and he just recently had a problem with too much flow. Maybe he'll chime in.

You can't have too much water flow.

I didn't think of a ball valve on the return.... can you mount an external pump with plumbing on the outside of a glass sump? just run a big I-I over the top?

Most people drill the glass tanks for the external sumps, but I have done the "U" tube up over the top. I only used this system as a temp., but I can't think of a reason it wouldn't work permanently.

even if the power went out, you would still have access to the water that was left in the tube to start off the pump again. Would the air go through? I think it would work, Maybee I'll try it.....

You can if it blows your corals right off the rock. Also, I had a lot of tissue blown off a green slimmer when I put it in a really high flow part of my tank. I didn't notice until the MHs went out and the side facing the current didn't fluoresce like usual under the actinics. It did much better when I moved it to an area of less flow.

IMO, caused by too much "direct" flow... There are different types of adaptions/diffussers that still allow an intense flow without the flow being so intensified in a stream.

Repto- Right On! Exactly what I'm thinking. You can't have too much flow.... maybe just not enough rocks in some situations.

my buddie suggested pointing it at different sides of the glass to amke a swirl affect in the tank.
Well here is what I did.... I needed about 12" of 1/2 inch PVC bought 10 feet...
over the top.
to the pump
ball valves in and out... that way I can emergency shut off all lower tank flow... Needed the out cuz it was overflowing the overflow.... How can I increase flow rating easy? Maybe thats a different thread...
now the flow on a single side is about 18 inches. I deceded not to run both outs cuz it slowed the flow too much. Plus I had a powerhead that froze up and was zapping me a little yesterday. I don't know how long it has been out cuz I haven't stuck my hand in the water for a while...... the fish seem ok though....
flow "stops" at my finger.

Your pump looks like a fairly new Little Giant. BTW, every angle will decrease flow along with narrower plumbing... Remember to oil the pump every six months, or so.

In the housing is a fan like those you see on an alternater... be sure to open the case about every six months, blow it out, get as much as the dust n grunge out and oil the barrings.

I've heard that the new LG pumps have sealed bearings requiring no lube.
Skye, is it noisy... like a garbage disposal ?

Most of the new pumps are sealed and do not require any bearing maitenance. I'm adding a BlueLine as a return pump and am planning on having my 55 gal glass sump drilled. Skye - How will the pump prime itself following a power outage? Are you relying on whatever water remains in the tube from the sump?
