cracker

Beautiful job mate!

Has anybody got any excees reef rack laying about. I need a little bit to raise my skimmer. Or where do I get it from?

My phosphates are down to 0.02 and Nitrates 8

No.

Brain still not quite right, but everything else awesome.

You will probably find that the skimmer removes a bit more when the material is removed.

I used to run a 10 micron filter material in my sump as a pre filter and the crap it collected was amazing. Cant use it now as I have turned it into a refuge and it grows too much hair algae if I leave it in. (Fuge lights 24 hrs) The good thing about this material is it is too thin to harbour nitrifying bacteria, so you can pull crap out without producing nitrate. I have nowhere to use it now, but if anyone wants some PM me. I got quite a bit left.

local...my nitrates are dropping 2 ppm every 4days.

I dont feed mine either. I have a BTA and an LTA. They get some through filter feeding.

Nice tank westy, impressive.

I have moved her up to just under halfway in full light. Heres hoping.

I agree that a clean tank with minimal or zero mechanical filters along with heaps of LR would be the most efficeient way to remove DOCS etc.

I realise there is lots of oxygen in the tank water, but in comprison with something similar to that and a trickle type system, the trickle type system is going to house 20 times as much nitrobacter then the tank water. In other words, the production of Nitrate from a small internal submersed powerhead filter, (If stupidly used for something else), will produce such a small fraction of nitrate IMO, that it would be barely noticeable on the grand scale of things when it comes to Nitrate production.

Wife invasion in this hobby is standard issue I think..... :-?

Cheers, so it is making a big difference then? I might have a nosey.

I have to agree with Alois on that one Steve. Whats your point?

Sometimes the obvious just clean escapes me. Sign of intelligence they reckon!! I will try this thank you Chim.

...and fresh salt water.

It indirectly produces them.

Oh, of course, simply through trapped decaying matter. forgot about that!

Nah! I moved it away because it went like that up high to start with. Now it wont go back to normal!!

I know they shouldnt be used, but I am interested in this topic!

How do they produce nitrate under anaerobic conditions? Nitrobacter needs oxygen to convert trite to trate. you think maybe from small amount of bubbles perhaps caught in the filter?

The good shot is when the coral was really high in the light. It went horrible and I moved it under a ledge down the bottom. Bloody thing, It was awesome before.

Nah, she is well away from the light. No sign of decay.....maybe needs less nitrate. Which is moving downward quick.
