diy skimmer build!!

Yeah, It's going to be a recirc. I've never heard of the 6oolph of air per 100gal of tank volume rule for SPS. So, I hope someone can chime in. How do I convert scfh to lph? How many layers of mesh are you going with?

this is oscar and he would like to say thanks to all for input on this skimmer

 

[freetareef]

i used 4 layers of mesh. i think that 500lph was a manufactures recomendation and every one on the thread was like "whoa, 600 at least" i'll see if i can find it.

my hand hurts. lol

500 lph per 100g display for sps quality water is what i have always prescribed, and will be plenty...
deltec reccomends like 300lph or so for sps tanks.

 

[rlugo29]

So, for my 55g that has a total water volume of about 75g, I should be looking for 275lph? How do I convert scfh to lph?

Scroll down, near the bottom of THIS page is a scfh to lph converter that you can save.

I don't have excel and do not want to buy it for one time use

SCFH*0.472=l/min *60 =l/hour

The wp1000 needs to have its pw dremeled down in half, then 4 layers of flatback mesh should be added, then a 3/8" air hose barb should be used with a slit in the one side and you should push it into a 3/4" pvc male fitting. It will give you 30-40scfh done correctly. It needs a 3/4" restriction to pull the most air. A 3" neck is going to top out at around 20-25scfh. You can push around 40-45scfh through a 4" neck.

The wp 700 isn't a good pump because it has a 1/2" input. It'll pull 10-15scfh air max. If it had a 3/4" input it would pull 20-30scfh but it doesn't.

 

[rlugo29]

Thanks Don, but I'm not the brightest creature on the planet and have no idea what that means.

 

[luke33]

yeah, 4.5" would be even better, agreed, but 4.0" will do 35 scfh fine, that's what a modded octo nw-200 pulls through 4.0"

NW200 original has a 3.75" neck

yep 4 inch neck it is.

 

[rlugo29]

Willy, Thanks for the download.
Useing the converter 10scfh=283lph & 15scfh=424lph
So, if Luke is correct about the WP700 only doing 10-15schf & I go with 500 lph per 100g display for sps rule, I think I'm safe with the WP700 on a 3" neck for my tank. What do you all think?

 

[rlugo29]

freetareef, how many gph do you plan on pushing through yours?

 

[rlugo29]

So, according to the chart the WP1000 @ 30-40scfh will give you 850-1132lph

 

[freetareef]

yea!!! lol!!!! that should clean er up huh!!!! i haven't decided on flow yet... i want to utilize my overflow lines as to not add another pump... if i use both lines i'll have 300gph and one will be 150... maybe skimmer or luke can chime in once again... i'll do some more reading tonight. oh yeah here is a pic of my hand lol!!!

 

[luke33]

For a feed pump or overflow feed you want 1.5-2x's the display volume so if its a 180g i'd push around 350gph flowthrough.

Rlugo, the wp700 will be plenty for a 55g.

 

[rlugo29]

Thanks Luke33!!!

freetareef, That's one nasty cut. I'm glad you're OK. Here's some info on feeding recirc skimmers.

Is 6" PVC available at most Lowes or is this a store by store thing? I am thinking of playing around a little and the cost of PVC is much more appealing than acrylic.
