'Starving' tank...

[drcb84]

I'm having an issue with brown algae, it's on the decline but wondered if not feeding would help..

Basically I'm really unsure as feel it is a bit mean...

But would it help with getting all the crap out while putting nothing new in..

And how long could I not feed for without hurting the fish.

I have 7 chromis, 3 clowns, 2 engineer gobies, royal gramma, 2 Angels, a Pink spot goby and a small Anenome..

Total water vol inc dump is around 250 litre and a LOT of live rock and a good few soft corals.

All are healthy and no other issues apart from the brown algae.

I have VectronUV, BM E3 skimmer, 3 big powerheads.

I've done water changes, but my RODI unit isn't so quick so I tend to do 25-50 litre changes but doesn't seem to be making a difference on the algae.

I prefer to avoid solutions I can't keep long term so if you stop feeding now and things improve you might have solved it temporarily but eventually you have to feed again. Its all about havign enough filtration and water changes to match the amount of nutrients you are introducing by feeding.
How old is the tank? maybe its still cycling? what are your phosphates and nitrates readings?

Tank is over 6 months... All kicked off after my LED's failed so I hastily installed 5 20w 24" t8's (from 20000k to 6500k) a few weeks ago Ammonia is zero, nitrites 0 but nitrates are high... Phosphates I don't have a kit for but I do run aquaphos and only use RODI water. It may be me over feeding... I've never really known how much to feed anything from 4-6 frozen cubes a day....
