While fighting dinos, no WC allowed. What elements would be depleted?

[David Cher]

it is around 8 months old. i think it might be due to the reason i removed one of the marine pure blocks from the tank

That could be. More likely stirred stuff up too.
It's still young. So it's hard to balance sometimes. It'll pass.

i tried with cyano clean and also a balance but does not work . i thought when having cyano , the no3 and po4 will be 0

Yours look like diatoms to me

Yea a bit. Did you look at the video? Looked a bit stringy. Wasn't sure.

 

[David Cher]

what i do now ? every day siphon ? do i still do water change ?

Diatoms with a bit of cyano I believe. For cases like this (a little bit of diatoms or cyano or both) I would increase the flow, if possible point your wavemakers at those area (without stirring the sand). It will help (less visible) whilst you take care of nutrients imbalance and establishing the natural biofilters.

Diatom usually will fade away with light. If hardly can be seen before the first light then it is a diatom. Cyano usually remain visible because its a bacteria.

it is the whole sand bed . i am having 2 x 6105 already .

 

[David Cher]

do i need to pick up more pumps ?

 

[David Cher]

 

[David Cher]

It is a peninsula tank

 

[saltyfilmfolks]

do i need to pick up more pumps ?

IMO no. Most of these things really do go away with time. If they hang around then it's a problem.

Diatoms by the way. Will be a dusty kind of texture. Cyano is slimy. Dino's are snotty.

That tank looks pretty good.

 

[Donovan Joannes]

Having more powerheads not really necessary. It depends on direction it points to, rock arrangement. I would advise putting the other 6105 on the opposite direction to create random and turbulence waves. That will ensure a proper flow all over the tank.

If your running filter socks you can stir up the sand bed too the night before you change them.

One of the 6105 or both ???

 

[Donovan Joannes]

As per @saltyfilmfolks, usually diatoms and cyano will go away once your tank matured.

One only. Personally i would place them facing each other at farthest end to create turbulence. It's a try and error as you have to adjust the mode and the speed. The angle they face each other will create kind of flow you and your coral liking. Give it a try.

Furthest end????

Farthest end if rectangular. For cube it doesn't really matter as long as they are facing each other. You have to play around the exact placement. Your current placement (both at the same end) will create a slow flow zone underneath the pumps. Something like this...

thanks you so very much

No problem. Good luck with the pumps. Just be careful with the speed and flow direction. Don't ripped off your corals and blow sands all over. I programmed mine in alternating mode to keep particulates suspended all the time. Cleaner sand and no dead zone for detritus accumulation. Oh... detritus is good for corals too (fine food).

 

[Hans-Werner]

To me it looks like Prorocentrum lima, a benthic dinoflagellate of reef environments, frequently found on algae and dead corals (live rock).
I once had them and fought them successfully by siphoning them during water changes, so water changes must not be the point. I had problems with this dinoflagellate using tap water for setting up the tank and managed to remove them changing to RO/DI water for water changes.
