brown algae,someone said to increase low level current in water--i have a 46 gallon tank with an emperor 400 filter i believe??????with about 15 lbs of live rock and 30 lbs of live sand---what should i do to increase water current??i was instructed this was more than enough filter for this tank or is there something else i am lacking?any suggestions appreciated

 

[mh51072]

so what do i need--im new so sorry if i seem a little ignorant--thnks

Its not the filter,its the water flow. You should put in a power head to move more water around.

do you have any powerheads?? if not, i'd get probably 2 or 3

 

[mh51072]

a power head?????what exactly is that???

 

[fshhub]

tang, depending on flow, i like having more smaller onew, for better coverage vs. flow(got 5 in my 75)

and to answer your q they are submersible pumps which you put into the tank for water movement

do they hang in ur tank or what??never have saw one before--and thanks again

 

[fshhub]

some come with suction cup haners, that you hang on the glass and that is pretty much it, hagens are real good, i gout a couple myself, and they do come with hangers, some others don't have the hangers

add more powerheads to increase the current <img src="graemlins//yeahright.gif" border="0" alt="[yeahright]" />

hey mr tang--where can i order those powerheads??

 

[fshhub]

you can always hide some or all behind the rock too, i do agree with you, too and most only have 3 - 4 in 75's
and yes,they will increase circulation, and help by not having any stagnant areas in your tank, i like having a total combined flow(all sources including your filter added) of at least 10x your gallonage per hour, example for you would be 460 gph+, i have almost 20x at different levels facing in different directions(no whirlpool)
