flow in SPS tank , confusing

[chercm]

i am very confuse how much flow is enough for SPS tank . i have 2X wp40 running else mode 3/4 way and 1 x WP25 on the same setting.

I am kinda of paranoid that there are some brown algae on the rocks and some of them have tiny bubbles on it too . should there be some growing on it ?

should i be directing the flow on the rocks or just hitting some glass ? when i direct on the rocks , the no3 and po4 increases . what should i do ?

sounds like could be dino's or carbon source (zeostart 3) overdose

i have been running zeovit for 2 years . for the past 2 weeks i have lowered the dosage for start3 to 0.5ml from 1ml . i have rescape the rocks 2 weeks ago .

my tank is 586l

Does not seem like a flow issue...
Run some tests so you can see what your water chemistry is like.

If you are having cyano issues add some coral snow every three days for a while.

i stopped using Rowa phos and using concentrating on Zeovit . the issue is that the no3 kept getting stuck on 5ppm when i look from the side

Is it cyano ?

looks very similar to cyano

looks very similar to cyano

it is brown only not the red stuff

seems that my radion is running at 100% intensity , if i lower the intensity to 55% will it reduce cyano ?

I'm having the same problem, zeovit slime and all. Coral snow after three doses reduced the slime to 20%. Mix it with some zeobak and try it.

this morning i got the brown algae when the light came on . can i scrub it and does it spread ?

 

[chercm]

Anyone ?

I have had success scrubbing that film algae away. Keep with the coral snow/zeo bak or biomate dosing.

 

[chercm]

Is it due to cycling process or it is due to lighting too bright ? I am using led

You do have a clean up crew right?
