View Full Version : Coraline dying? in my FOWLR

08/13/2008, 08:10 PM
These used to be covered in purple.
Pretty rapid decay of algae in the entire tank - every rock has this problem. Has been going on for about a 2 month period.
I've had tank up for about 11 months. Added a fuge with calupera(sic) about 4 months ago.
I do not dose anything; all parameters are NORMAL. What should I do? Have you seen this? Do you have any questions that could help you identify my problem?
Take a close look at the pictures. If something looks wrong ask me about it and I'll answer the best I can.
Plesae help. :confused:

edit: sorry about the images not showing up in thread.

What are your water stats?

08/13/2008, 09:21 PM
ph 8.4
salt 1.025
temp 83
no phosphates nitrites
running a carbon reactor, skimmer

does that answer your question?

Thats horrible. What kind of lights are you using, and water changes.

Calcium levels?

I didn't ask the question, but no it doesn't answer it.

Need to know the Cal, Alk, and Mag levels.

Also, if you recently switched lights to something more powerful than the coralline is used to, this can happen. I've seen it on friend's tanks who have gone from T5 to MH, the coralline dies off on the tops of the rocks where it is exposed to much more light and different spectrum than it was used to having, but still continues growing well on the sides and bottoms of rocks.

Is it realy such a bad thing, I thought live rock with heavy coraline coverage get choked and dosen't work aswell. I hate the stuff and was glad when my urchin ridded the tank of it.

I don't know the Cal, ALk and Mag levels as I do not have a test kit for those things.
I'd pick one up if you could recommend one on-line.

The lights are about 3 years old but I haven't switched anything from 4 months ago when everything was good.

I started putting 1 cap of purple up (2 weeks now) every 3 days (75 gallon tank by the way). I haven't noticed any help yet. Maybe I should put more?
I do a 15-20 gallon change once a month.
I want to set up for coral eventually but obviously I'm not ready to. I've read and read but I can't seem to find just a simple guide of: "here's what you need, here's how you set it up, here's when/what you test for"

This looks really bad, if you don't get it rectified soon, your fish might be next.

I don't like a ton of coraline in my tank either, urchins are the answer... not bad Cal, Alk, and Mag levels! Be sure to check those soon.

Good luck with it, hopefully its nothing major!

Answer me this.
Do I need to even check Cal, Alk or Mag levels???
Would you suggest I just start dosing the Purple Up a little heavier?
It recommends 1 cap for every 50 per day...of course that depends on the load.

What would actually deplete those things other than time?

I have 2 fish and no coral in 75 gallons.

Don't take chances! Get a kit or take a sample to your LFS and see if they will test for you.

You really need to know what is going on before trying to fix it.
