How to make Vortech run at maximum speed

i have a vortech mp20 that i run at reef crest mode. And i am getting growing cyano problem, i know there are other things that causes this algae but first i want to rule out not enough flow. I also keep some SPS and plan to get more. I will be picking up a K3 tomorrow at the lfs so i have even more flow.

And when reading through the instructions i couldnt find out how to make sure it runs at maximum speed. So anybody know how

 

there's a little nob on the side where the mode an reset buttons are. Turn it all the way towards the "+"

I'd try running it at max in constant speed mode and see if that helps

 

ok i will go look for that, thanks lol my sps corals are going to love the increased speed and i hope this makes the cyano go away but if it doesnt ill be forced to setup a HOB fuge because its getting really bad

 

alright its adjusted and sand is starting to fly everywhere fish cant seem to keep up with the increased flow, lol they better get used to it. I think i still need to pick up another powerhead tomorrow, but i think ill have to place it as far up as possible to try to minimize sand getting thrown everywhere

 

LOL, they really throw their weight around! My mp40 is in the middle of my 24" tall 80g and it still makes a vortex from the surface of the water

 

lol thats one powerful powerhead mine is placed as close to the top of the tank as possible. And my "junk" that's been at the surface is almost gone ive got a little bit left but i think once i get the K3 it will all go away

lol the fish are spazzing still trying to get used to it, and the chromis is mad and getting tossed around and is taking his anger out on my mccoskers flasher. lol tomorrow their really wont know what hit them their going to be tossed around even more

 

LOL, that's how you keep from getting fatty fishes

 

lol ive noticed my melanurus has been looking a lil plump, could be from him eating all those ceriths though

 

Strong flow can help prevent cyno, but if you have excess nutrients, then it will grow anyways. I've had it grow right in front of a power head and even on the power head. The sand should be stirring up with that strong of flow, you may want to turn it down.

 

all paramater have been reading 0 so im hoping the increased flow will at least help a ltttle, mine hasnt been on the powerhead yet but its been growing on a rock right in front of it and on other rocks and sandbed. I just ordered a hydro evolution 1050 so i will have a crazy amount of flow in my tank now and the sand was also being thrown around on the lowr speed as well, just not this bad, and ive got it placed as high up as i can
