Water changes and exposed coral

[Neptune1707]

Looking to upgrade my 90g acrylic tank to the new Red Sea S Series 650 (175g) in spring 2015. I will use my existing live rock, but will be buying more. When aquascaping, I noticed a lot of these beautiful reef tanks on your site, have rock/coral going right to the water line. Are there issues with exposing coral to the air when you do 20% + water change? Should I plan on aquascaping up to where the tank water level has 20% taken out. What is the rule of thumb here. Oh currently only have mushrooms, chalice. Would like to get into Acrapora and others to diversify tank.

Corals sit out of the water when tides go out so it's not a huge deal for alittle bit.

I agree, they are out for fragging, bagging, etc as well.. I have a couple now that stick out during water changes, and have had several in the past with no harm... if too worried you can do water change from sump too

I have a couple of acros that are out of water for 5-10 minutes during water changes. I reach up and splash a little water on them every minute or two while the tank is filling back up. Never had any problems.

Welcome to r2r!
I agree with everyone else. There's no issues with that.
In the wild as the tide rushes out they (mostly SPS) will be exposed for quite some time with the hot sun beating down on them. That's what the slime coat does, it acts like a sunscreen. They've developed a natural behaviour to avoid harm while exposed to air

I used to know a reefer that would drain off about 15-20 gallons from his 90 and THEN go to the fish store to get fresh salt water.

My corals always get exposed during water changes for more or less 5 minutes,

What in the heck is that giant jelly looking thing in the second pic?

my vote until clarified is that its a big elephant ear corallimorph

looks large lol

It has been rumored that corals can actually benefit from short periods when exposed to air. When exposed long enough they will secrete a slime coat.

That is a Red Planet sps that is growing against the glass!! Needs some fragging!! Look here from the side of the tank.

nice one luis, nice




neat fact about corals and glass

lps dont bond to glass

sps do
amazing

Now that's a frogspawn!

Ten years in my tank. Around 200 heads!

I kept a Anthelia Waving Hand Coral that I kept out for a half or so that was not too pleased with me. It stayed in a half deflated state for 6 more or so until it finally rebounded a returned to normal.

this is a macro of blue sps perma bonded in my reefbowl, and contrasting red war coral skeleton creeping up glass appearing bonded but not
its striking physiology, allright whos grad thesis is it going to be to tell us why lps wont adhere at the microlayer level to glass while the sps/glass bond is stronger than the glass itself so to speak

look at how sps lays down in an amazing squared cross hatch ability, natures fractal squares.

and, predict who won the turf war

not what you'd expect ~

My answer.

Also, amazing frogspawn colony!

 

[brandon429]

Ha
That rocks


A million bucks worth of retail priced sps all at a cool 80 degrees emersed for countless thousands of years daily. Dang.
