Do I have enough water movement?

I just made my own Spay bar and not there isnt much water movement in the tank, is this a problem? Do I need to get a power head to create some movement? What are the Pros and Cons to not having much movement

I can only think of cons. Maybe your water won't get filtered completely and it might be easier for algae to take hold with less flow. I dont really have any pros. I have a fluval 305 and two powerheads running in my 60 gallon. One of the powerheads even works as a mechanical filter.

Depending on the size of the tank your using, I highly recommend a Hagen Mini Elite. Its a pretty powerful powerhead / mini filter.

Shoot for the stars...If you miss, pray your not close to the sun.

i should have asked this too. did u make a intake pipe with ur new spraybar?
how many holes?

it looks like the cannister is rated at 340 gph. i'd try 1/16 holes. and about 30-40 of them

No i am using the intake from the fluval its perfectly fine. i have 36 holes, What would making them bigger help with? would the smaller hole force more water out?

when reducing the diameter of the hole. for instance going from 1 inch to 1/2 u don't cut the flow by half. its more than half. i don't know the exact numbers or calculations but i know that it is greater than u think. 1/64 is a terribly small hole. i looked up a few calcs and it ranged between needing 200-2120 holes at that size... i'd drill them at 1/32nd and see what happens. and go up from there if neccessary i made my own intake pipe to be scrimp safe and i drilled about 300 1/32nd holes and used 3/4 pipe..

I believe a dead spot in the tank with no circulation can cause rotting in plants, a less from what i see in my tank.
