Do you consider this as high bioload?

[ahchung]

I have a 50G tank. Currently I have the following livestocks:

- 3" Naso Tang
- 2.5" Yellow Tang
- 1.5" Clown X 2
- 2" six-line wrasse
- 2.5" algae blenny
- 2" Cleaner shrimp X 2
- Blue-legged hermit crab X 2
- Some SPS colonies and frags

Tank shot is shown as below:

I am running a Remora Pro skimmer.

Currently I am encountering cyanobacteria on the sandbed. I don't know whether this is related to the high bioload or not. NO3 and PO4 are zeros.

Should I remove some fishes to fix the problem? Please kindly advise.

 

[clkwrk]

IMHO yes

 

[ctxmonitor]

as long as you have a good skimmer and the color of your sps is popping, then no. you might be even able to add more

 

[clkwrk]

I guess you missed him saying CYANO problems ?

+ two poop producing Tangs .

ahchung- What po4 kit are you using?

 

[Wiskey]

I have to agree with Clkwrk, sorry. For reference I have a 50 gallon tank too, and I have

2.5-3" yellow tang
1.5" Fase perc
1.5" six line

and I have been told by most that I have a med-med high bio load, because tangs are "poop macheens" and the yellow tang will get bigger.

Not everyone agrees, but that is what most say.

High bioload... yes, that's what I am thinking. Some of the high requirement frags lost their colors. I need to fix this.

I think I will get rid of the Yellow Tang, six-line wrasse and the algae blenny since they are not doing their jobs (i.e., consume Dictyota and various macro algaes and pests).

How do you think if I just keep:

- 3" Naso Tang
- 1.5" Clown X 2

Should I drop the two clown fishes as well?

 

[ahchung]

I am using Antiphos Fe and PO4 minus. But from the well beginning my PO4 was zero using Salifert test kit. So I guess the tank has sufficient PO4 to feed the cyanobacteria even though majority is skimmed out.

[johnvu713]

IMHO i'd ditch the tangs and keep the rest

 

[ahchung]

Trust me the algae blenny produces a lot of poop as well.

 

[MiddletonMark]

I'd dump the tangs as well. They'll only grow bigger ... and IMO that's a lot of bioload in that tank.

IMO, get the corals popping - then start adding the fish.

You do realize that Naso will grow to be 8" or more, right? Its a beautiful fish but it needs more than a 50 gallon tank even if you have no bioload.

The cyano may be a product of low water flow in the bottom of the tank. Increase flow and put a polyfilter in to deal with the cyano. You should be able to make it go away quickly.

 

[RichConley]

8" is a tiny little naso tang. They get huge.

The bioload isnt bad now, but it will get HUGE with those fish.


Also, is 2x bluelegs all you have for cleanup ccrew? You definitely need more of that, if so.





PS. I love the aquascaping.

 

[turtlespd]

you can always get a larger skimmer or go with a refigum with macro to remove organics is you want to keep a high bio load. I keep a high load also and things look ok. Alittle algea but i refuse to give up my fish. You can also feel alittle less. Once a day or twice a day but with small feedings.

 

[SunnyX]

I would ditch the Naso Tang, tthey grow up to 18".
The rest of fish should be fine.

 

[DMK]

i agree w/ SX.

 

[jay24k]

I'd keep the yellow personally. JMO though. The naso I wouldn't. They get big and big quick.

 

[ahchung]

I keep Naso because I had a Dictyota outbreak and only Naso in my tank consumes Dictyota. If the Naso grows too big, I will release this back to the sea.

According to my understanding, Naso exists in our ocean area.

 

[clkwrk]

No PLEASE DO NOT RELEASE INTO THE WILD . That would be irresponsible IMO . A fish brought into the aquarium trade and into hobbyist tanks should never be returned. As they can take diesease back and other things.

 

[shadofax69]

I agree if you want to get rid of the tang take it to a store or give it to a friend but never release something like that back into an ecosystem. Like clkwrk said it could release a disease or other parasite that is not common to those waters and decimate a ecosystem. JMHO

 

[shelburn61]

Why release it? Better to trade or sell it so that 10 more aren't taken from the wild to replace yours in someone else's tank.
