sump/fuge size

[renogaw]

hmm, only playsand i could find was made by us silica company. I'm assuming that wouldn't be very good. so i went to a store on my way home, and they had 30 lbs of semi moist carib sea argonite sand for $30 but was dated 4/06/06 and brown.
so, i got 30lbs live sand from the auction site for $25 LOL.
we'll see how it is next week.

 

[renogaw]

also got 15? lbs from team2jndd (no, i didn't accept it for free so now my dilemma is this:
45lbs of sand being usps'ed to me, i'm assuming i'll have some die off. I think i'm going to put it in my unused 10gallon with some water and a powerhead/heater to let it settle and see if there is any die off. i also have some rubble rock coming from nakadoc so that will go in as well
I am contemplating putting my piping all the way to the bottom of the sump and angleing the pipe so it sorta swirls the water along the bottom so there's nothing sitting in one place, then building a shelf for the rubble rock so the water rises up through it, gets skimmed out, then goes up and over the baffle to the fuge area.

GDI i'm ticked

team2's sand is great, the sand i got from E--- was totally misrepresented and i'll probably stop paypal payment. was supposed to be pure white sugar sized oolite sand, and it's brown almost CC sized sand.

this seems to complicated i have bought a tank tryed makeing it i gave up and im going to buy one

 

[renogaw]

nah, once you set yourself to do it it doesnt take much

The egg crate you used in your sump... is that the same stuff everyone talks about putting in as a tank lid? BTW this is spinning my head! I have an overflow already and the rest coming next week to build my sump and... well no way it'll look close to that good but I hope it still functions!

 

[renogaw]

yes, its the same eggcrate, you can get it at most building supply stores, or the big box stores like Home Dumpster and Lowes't Quality

 

[larryndana]

i'll also point out that its in the lighting section and isn't called egg crate, i forget what they call it.

 

[renogaw]

actually, i've asked for it in 2 different stores as eggcrate and they both knew what i was talking about

 

[larryndana]

wow, i feel like idiots are following me around. no one knows or understand what i'm saying, then again....maybe it's me.

A few dumb questions:
Will a 10 gallon sump not be enough for a 75 gallon? A calculator thing said that 7.5 gallons would be enough.
Can you not use plexiglass for the baffles?

 

[renogaw]

the bigger the sump, the more volume the water you can have through it. also, the more room. if you can fit a bigger one, try to.
as for plexiglass: i used it in my 10 gallon fuge, and it was always bending in the middle, and it was most likely going to crack if i kept on using it. some people say silicone won't hold it to glass, but i put enough silicone on it where it did.

im building everything the exact same way you did refugium, overflow everything this post has really been an great help thanks to all

i'm wondering if your siphon ever brakes, and what do you do? or if its possible to brake?

 

[renogaw]

i'm thinking that's why the tee is above the water level.

 

[larryndana]

yeah, mee too. i'm wondering if the lenth in the tank should be shorter, incase of a power outage....all the water from the dt would end up in the sump/fuge or on the floor.
sorry don't mean to highjack your thread.

This is a great solution... siphon wouldn't break due to the double "U" design that takes the water down then back up. Also, power outage wouldn't be a problem either as the height of the 2nd "U" coming up determines the water height in the tank. If you notice, it won't go below it's current level because the function of a siphon is to make all segments the same level. Since the overflow portion of this concept where the PVC is open, that level is as far as the tank would level to in event of a power outage. Great idea that I will definately use in the future! Thanks!

i beg to differ. The siphon can break. You raise that out of the water, then put it back in it will not start right back up. I tested this out last night with some PVC pieces i had(surprised i had all the elbows) it does break, even if you shorten or lengthen the sump side pipe.
and yes, it will overflow if there was a power outage. See the reason this was going to be used was to attach a sump to a fuge. if the power went out, the return pump for the fuge would cut off, the tank would continue to drain, filling the sump, while the sump is filling, the fuge would continue to fill.
inevitably causing a overflow.

 

[larryndana]

I think i see now. it wouldn't overflow. the open end on the the pvc is just like if you were draining water with a hose and lifted the hose to the waters height....it would stop the flow and would stay at the height of the water level in the tank.

Wow, I see it now. Thanks.
