This is a new one on me but bear with me....
I run an algae scrubber and my nitrate and phosphate is 0.
The tank has been running in one form or other since jan this year and has been completely skimmerless since about june.
Now I've had NO problems with nit or phos relating to the scrubber or lack of skimmer, infact I would NEVER be without one!
my corals are growing like mad and I'm really really happy.
One think I can note is that although some of my sps are pretty bright green and orange, everything else seems a little duller that I expect.
Now.... I was speaking to someone who runs over 30,000 lt of systems and has nearly £250,000 worth of stock, corals and fish (self owned retailer) and he was quite positive about algae scrubbers
He did however say that in a closed system he wouldn't advise running without a skimmer. He claimed that high level of protiens, like in a skimmerless scrubber system, the high level of protiens would cause browning of corals.
Is this true and is this why my corals are pretty dull although they do grow well!!!
Just putting it out there!
