Reefers with 10+ yrs - what's the one thing that was thought to be true 10 yrs ago but is now in current times DEBUNKED?

.......................................

For me, 10 yrs ago it was said over and over again in posts:

"White light makes the coral grow. Blue actinic light is ONLY for human eyes and ONLY makes corals 'look good'....doing little to nothing for coral growth"

Then Kessils came out and changed everything... LMBO

 

[GoldeneyeRet]

Nitrates needs to be 0.

 

[C. Eymann]

LEDs can grow wicked SPS, maybe not as fast, but color development is much more intense

 

[Thaxxx]

Doing DIY things make reefing affordable.. Ummm not.

 

[Vinman]

Coral was expensive.........

 

[Tahoe61]

Only 2 clowns a female and male can co exist in 1 tank.
Vacuuming a sand bed is forbidden.
All phosphates must be removed.
PC lighting is not appropriate for any SW tank.
Bacteria in bottle do work, yes they do.

 

[Roosterjack]

You can’t keep marine fish in a small aquarium.

 

[HB AL]

Leds won’t grow acropora’s.

 

[HB AL]

So called not reef safe fish can’t be stocked in a reef tank, tell that to my triggers.

 

[RevMH]

I knew at least 80% of all reefing. Every year, as I learn more, I realize how little I know.

Who said blue actinic was only for human eyes? I have never heard that.

For me it is ULNS is the way to go. That may have been more than 10 years ago...lol.

It was the mainstream thought on TheReefTank and ReefCentral circa 2007/8/9.

Opinions changed in a 180 degree swing when Kessil lighting became popular in 2010/11/12. Orphek soon followed.......then all the major Mfgrs broke loose with deep actinic light systems by 2014.......By 2015 Chinese Black boxes took off like wildfire on eBay

This was more than 10 years ago... people used to say you couldn’t color up acros with t5 lighting.

Interesting. In the 90's it was well known that actinics were essential for growing corals. I started reading forums about the time LEDs started becoming popular. No wonder people thought they were better. People were giving out wrong info.

100% debunked:

-when removing a sandbed, one must remove in portions to give time for live rock surfaces to take on replacement bacteria.

False.
If a given amount of live rock alone is enough surface area to handle X bioload alone, without sand, then removing sand or six extra canister filters we may have opted to run immediately doesn’t automatically make that same rock surface area lacking. If it’s not enough surface area, partial sand removal doesn’t make it gain surface area and stacking bacteria on top of bacteria doesn’t increase surface area it lowers it. rocks don't take on replacement bac from missing sand, their spaces were already full before the sand removal.

Surfaces self regulate bacterial density through actions like water shear and space competition

Removing surface area that is gross in excess of oxidation needs doesn’t leave the remaining surface area weaker.

The impact of the change is freedom to do things with your sandbed so it doesn’t kill your aquarium, without hesitation. we’re free to act now.

Work example

Went bare bottom!

Was tired of detritus buildup and ugly algae and gunk built up on my rocks so I took out all my rocks and scrub them all except the one my Nem was attached to. All sand removed and inhabitants was added back after the tank was thoroughly cleaned. Hope nothing goes wrong. All fish and corals...

Things that have changed from when I started 20 years ago:

No such thing as a frag, a full colony cost $30-$80

Damsels were the only way to cycle a tank

No one had a tank without a sand bed and I don't think I ever heard about anyone cleaning their sand bed because that would "disturb the good bacteria".

There was no such thing as LED lights for reefs, power compact and/or metal halide were the only way to go.

The more bio balls the better.

You had to actually carry around pictures of your tank if you wanted to show someone.

No hugely active internet forums to ask questions.

 

[tony'stank]

Measuring ORP was important and adjusting your ozone to achieve ideal ORP was vital for a reef tank

 

[biecacka]

SPS cannot grow in ”dirty” water. N03 and p04 MUST be zero


corey

 

[dnahas]

Bio-balls and bio wheels what a vhs tape of greatness.

 

[2Wheelsonly]

alk swings wipe out a tank. They are not good but having one here and there does no harm if your reef is healthy.
