Would this pump be good for 75???

[thirty5]

Glad to know that some people,on here, have a sense of humor. Thanks buddy.
I was told by the old school that 10 is the minimum. The more turn over, the more oxygen for your animals.

Damn do you mean you are going to charge me for that one??? Dammit!

But correct me if I am wrong, the actual tank turn over into the sump is really only for skimmer and reactors??? So if my skimmer cannot handle a 10X turnover what is the point??? I will be running an mp40 in the tank for flow in the tank...

On a pump that has a max head pressure of 13' running at nine foot, what do you think you'll be left with. 35, you should go with at least the 55 model.

looking at their curve charts,
BL40HDX- 9.5gpm at 10'- 570 GPH
BL55 -14gpm at 10' - 840 GPH
You have a 75 gallon tank, a 10x turnover would be 750 GPH.
I like my turnover to be 3-5X.
This decision would be totally up to you.

Richie did the calculations... He calculated that at 10' that pump will push 570 per hour so on a 75 gallon tank that would be 7.6X per hour. I guess I can goto the bigger pump and get more out of it. But my skimmer can only handle so much... what is the point of pumping water out of the skimmer that has not really been skimmed>?>

The lower floor system explains the few feet. Good luck.

Well, if the pump is to supply the skimmer. Then that's another story. I thought it would supply the sump. My bad.

Lmao... That's funny.

HAHAHAHAHAAH Its not for the skimmer! LOL

But isn't the point of a sump to hold your skimmer and other components to clean the water??? If your skimmer can only run at X gal then in theory shouldnt you run X gal through the sump?

Run your main pump at a certain GHP and then use powerheads in the tank for flow in the actual tank? You dont necessarily need to have the turn over through the sump. I have heard of people who actually use just flow and a HOB skimmer on a tank, there is no difference here..... So in that case you would not push more water than the skimmer could skim.

BTW this is healthy thread, someone can read this thread and learn alot!

great choices. imo in the order from least favorite to most
ts-790
bl-55
bl-40hd-x
my reasons are as follows.
Bl-40 is very quite compared to the other 2
bl-40 has more gph than both
1" in and 1" out, this is great
you loose a little on head pressure, but you had mentioned only about 6' oh head.

Bl55 is a tsd louder but not much compared to the bl40
you gain an head height but loose on gph at 0' head., but only 170ghp.
1" in and 1" out this is great.

Ts-790
best on power consumption, but loss of gph.
A lot noisier than the other 2
3/4" in and 3/4" out.
I try to stay away from this just because of my stupid mistakes of not putting netting on my drains, and having small snails getting stuck.

these are only my opinions.

Like I was saying, I like a slow flow thru my sump, and other like a fast flow thru a sump.

Here is a link to the flow charts of the BL pumps

:scratch:So, what you're telling me that an internal skimmer has a flow rating ?:scratch:

:scratch:So, what you're telling me that an internal skimmer has a flow rating ?:scratch:

Well since the Bubble Blaster Pump that comes on my skimmer is rated for BB2000s ? 25watts gph=300

So I guess yes, there is a flow rating..

 

[pauliwalnuts]

:scratch:And the same flow rate should apply when using an external internally ? :scratch:

WHAT?? You are losing me!! HAHAH :smash: :smash: :smash: :smash:

 

[pauliwalnuts]

Dude, you must be pulling my leg. That's the pump's rating, not the skimmer.
Btw, I did see that 90 rimless the other day at Aquatic Obsessions (all jokes aside).

don't change the subject now Paul bout the 90G rimless tank lol

You mean a Deep Blue 90 rimless?

this is the way I look at it. A skimmer whether internal or external, would remove more pollutants from your water if the sump has a slower flow thru it.
For example if water is flowing thru a skimmer at 900 gph and you have a pump on the skimmer rated for 300 gph, you are making contact with only 30% of flow. Now if you had 600 gph flow thru sump and the same 300 gph for skimmer you are making 50% contact.

 

[thirty5]

Right but if the pump can only pump that much water through the skimmer lol.

Whatevr I will prob get the bigger pump either way

DB make 90 but I have never seen a 90 Rimless

This is why I love richie! He made my sump and I set it up as he recommend, it's been flawless ever since! I pull out some nasty juice from my skimmer every day. My turnover is only about 4.5 - 5x but between the fuge and the skimmer my parameters are nearly always perfect. Listen to his advice you won't regret it!

PS: DB doesn't make a 90 rimless that's why I asked.

 

[pauliwalnuts]

Nearly always perfect

OK

I saw it with my own two eyes. Unless you're calling me a liar.

Cheap shot time. Lmao...
Rich, where's your NO3 and PO4 at ? Because last time I checked your tank, they were pretty damm high.
