How much gph do I need

[dangerfish]

I want to get a saltwater reef tank but im going to keep some soft corals so i don't know how much gph I need. Ill list my corals I want so you can get a idea.
Bubble Anemone
Feather Duster
Orange Montipora Digitata (Aquacultured A&M Aquatics)
Toadstool Leather Coral
green Polyp Toadstool (Aquacultured A&M Aquatics
German Blue Polyp Digitata (Aquacultured A&M Aquatics
Green Nepthea (Aquacultured A&M Aquatics)
Pipe Organ Coral
Anthelia (Aquacultured A&M Aquatics)
Ultra Zooanthid Polyps (Aquacultured A&M Aquatics) im still working on this type because I want a Zoa garden(if you want give suggestions)

Can't say without knowing the size of your system.

For the coral you listed I would use a 15X turnover rate but anywhere from 10X to 20X would probably be fine.

Just for clarification, not all of those are soft corals. The Digitata is an SPS. Not a very demanding SPS but they will need more waterflow than the others.

ok

 

[dangerfish]

so would that be 1500 gph

 

[bang guy]

so would that be 1500 gph

Like I said before, I can't say because I don't know the tank size.

 

[dangerfish]

my tank size is 75g

 

[bang guy]

Then a 15X turnover rate would be 1125gph.

 

[dangerfish]

What if I got one that did 1050 or one that did 1400

 

[geridoc]

Either would be fine. My preference would be 1400, and put a ball valve on the pump outflow so you can throttle it back if necessary. If you have the 1050 and need more flow you can't make an adjustment short of a new pump.

 

[dangerfish]

what if i got it for 1150 would that be fine

 

[dangerfish]

so would it be fine

 

[geridoc]

1150 will be fine.

 

[bang guy]

1150 is fine but don't disregard geridoc's suggestion.

Will this be a closed loop?

 

[dangerfish]

so im getting a Hydor Koralia Evolution Water Circulation Pump and i was wondering what size should i get
1150
1400
1500

 

[dangerfish]

and if i was to get a 1400 or higher where would i get a ball valve.
