tank too sterile

[smalltime]

I transferred my 90g tank to a 55g tank 2 weeks ago

Old 90g: had 1 inch sand bed, asm g-3 skimmer, 2 mp40w and a koralia 1400 behind rockwork, mag 5 return and 6 fish

New 55g: bare bottom, Tunze 9005 skimmer, 2 mp40w and a koralia 1400 behind rockwork, mag 5 return, 6 fish and 25watt uv run 6 hours a day with MH

Problem is the 90g tank glass had to be cleaned every 2 to 3 days

New 55g the glass has not been cleaned once in 2 weeks. All sps are maintaining color and showing new growth

I feed my fish twice a day and once a week(Saturday night) I dose aspartic acid and Cyclop-eeze blend

My tank has a couple softies but mainly set up for sps

Any advise? This does not seem natural

If your sps are still growing and have good color then what are you concerned about? Sps like very clean water, po4 at or near 0 and no3 <5. A new tank is going to be cleaner for a while. You will most likely have a small algae cycle soon.
