Need to upgrade the flow on my tank

[sillysidewinder]

I have a 25 gallon 18" cube tank. I have a hot magnum filter and 1 koralia 240 from my previous 12 gallon. I think I need more flow in my tank. Am I right? Would one more koralia 240 be enough. My corals are various hammers, zoos, mushrooms, Duncan, scans, etc...

get a mp 10 you wont be disappointed.

If the MP10 is a little pricey for you I would go with a Koralia 425 or whatever the size is they make now around that. The 240 is for a smaller tank like a 10 gallon or under.

Couldn't have said it better...I use a koralia for my 55 gallon until I get my mp40. But a vortech is an investment you won't regret.

Those would be preferences... flow will help, however just get whatever you can currently afford.
If you feel you really need more flow in a 25 gallon tank... but keep in mind that you may overpower what you currently have in the tank and make things a bit more shocking by adding too much flow. You want currents... not a hurricane in your tank.
:p

Nothing that you are keeping in your tank requires a lot of flow. I thought you said the magnum was putting out too much flow for your system?

i was wrong. i am a bit worried because i re-scaped the tank and lowered everything down. I moved the powerhead down slightly however my hammers are in different sections and neither are getting much flow. also, the flow isn't really getting broken up. the flow out of the powerhead isn't enough to cut across the flow from the filter so the water is moving in a circular motion on the top rather than a sporadic motion.

i'm also getting a light scum on the top of the water around the edges. people keep telling me that it is because i don't have a skimmer. what is it and is a skimmer the only way to get rid of it?

Hard to believe that you need more flow.
I have an Aquapod (24 gallon) and I find it has too much flow just with what comes with the tank. I spend a lot of time figuring out how to reduce flow. Hammers need to sway but they don'y like being whipped around. I have one hammer that barely moves it is is growing very nicely.

Ya I mean my hammers don't move much and are for sure flourishing. I thought it was important to have a cross flow with a random current. Have I thought wrong? Don't zoos typically like to be in moderate flow too?
