Any sugestions for a new setup

Hi All, as you were asking some pics of my tank.... any sugestions will be welcome, this tank has been running for 3 months now with that one fish, starting to get some brown alge is this normal?





My Tank maturing friend " colbie"



Filtration System


Dont have a clue what this is"? spot it on one of my rocks in the tank.

 

Hi Nick - If you don't mind me giving constructive critisism.... The rocks are going to end up "gathering" detritus, and causing a LOT of hair-algae, due to the detritus "breaking up" and releasing nitrates and phosphates (and other chemical compounds as well).... Otherwise, your tank has a LOT of potential.... I would rather want to suggest getting live rock (kenya, fiji, malaysian, etc) or at least "bio-rock" or similar man-made rock....

You have the right thinking with your sump - skimmer's cool....etc... do you have a DSB in the tank or sump? I cannot make it out....

 

OK Nico

The FW plastic plants need to come out

I would paint the background a nice blue.

I assume the water runs through that course crushed coral, read here same goes for the BioBalls DSB vs Bio Balls - Marine Aquariums of South Africa - wiki

That skimmer is it normally that empty?

OK having said that, with a bit of work and a few changes it could be a nice little system
