how many times a hour should the water go through the sump?

[MikeInToronto]

I'll use an example. Let's say you have a tank full of sea anemones. We'll make them ritteri anemones because they like lots of water flow. In this tank you don't want a PH, closed loop, or anything with an intake. The OF is fine because it is easy to safeguard an overflow without losing efficiency. How do you get the flow up to, say, 10x flow without using PH or CL?

Use a C/L with multiple inlets to reduce the velocity.the overflow box is still an intake. protect the C/L or powerheads the same way..

I'd assume you'd cover the intakes with sponges.

Why?

Providing the diameter of the intakes is large enough then the velocity would be very little, what size tank are you wanting to get 10x turnover in? if all you want to keep is Nems then build another box out of egg crate and shove the PH or C/L intake in there.

It might not seem like it but my anemone 6-8" diameter was pulled into my sump through eggcrate; actually it migrated through the eggcrate on the OF and got pulled into the sump. I have a FIFO system in my sump as well as a filter sock so there wasn't much of a problem. The anemone was ripped up a bit but made it. Sponge and filter floss are the only anemone-proofs I've experienced.

So how do you explain this comment? remember I have downloaded the whole internet and know who everone is and what they said

Sometimes it's easier when I don't understand what someone is saying because I can usually assume it is something logical. Other times I give them too much credit

If you put a sponge below the rim of the OF you won't be disrupting the flow into it. That should keep anemones out and allow surface film to go in.
People tend to pick at minor details - I'm not referring to you or anyone else here - so I tend to add all the "exceptions" to my posts to avoid people dwelling on them. See? I just did it again and didn't realise it. I was just imagining someone reading that original post and writing, "The OF has intakes as well, you know." I wanted to avoid that.

Also, I didn't have sponge or floss on the egg crate when the anemone went over.

That goes back to what I was saying about Every tank being different. If you do not want to use Powerheads, consider a closed loop. An intake is real easy to guard. Best thing is T the intake off a few times, then there is little suction at all the intake inlets, not just one. If you flow to much through a sump, regardless of skimmer, your going to introduce microbubbles. part of a sump's design is to be slow enough, add time/passages to let the microbbbles escape.

[banditpowdercoat]

No, don;t use sponges, Nitrate factories. Use Egg crate. If you have 1 1/2" CL intake, but you split it to T's. you now have 4 intakes, each one had a real low suction. an amemone won't get sucked in if you cover the opening with egg crate.

But were getting off the OP's topic here I think.
