A while back we had read a post from someone here on RS about changing out their bulbs. That jogged my memory and made me realize that the Corallife 50/50 PC bulbs that we run in the plastic canopy on the fuge needed changing. And..... that would explain the increase in algae growth as well as the beginning of a cyano outbreak on the top of our cheato. We have discovered that these PC bulbs colour shift very early and require changing out around the 4 - 5 month mark. I can't remember the last time I changed them (Ooops!! I have been remiss on my duties!!) We started to clean the fuge by isolating it from the main display and removing all of the live rock and fuge critters.
Live rock and critters are placed in buckets of siphoned off tank water.
Once we disturbed the substrate by removing the rock the water became real brown.... I wish we had thought of pictures before we started the cleaning!
The fuge was emptied and taken outside for a good scrubbing. This thing was disgusting!!
All of the live sand was scooped out and many small critters were discovered in there. We saved as many as we could find! We found four peanut worms and relocated those to THE 23 along with a bi-coloured bristle worm of some type. We think they are peanut worms? They tunneled into THE 23 substrate right away. Tracy was the brave one and she was doing the rescue work while I stayed a safe distance away acting the ninny that I am, (someone has to take the pictures!!) My girl is so brave!!
Once all of the critters were rescued the substrate was agitated and the debris was rinsed away in another bucket of siphoned tank water.
The bucket rinse water became brown very quickly!
The return pump had a good amount of "YUK" growing on it!!
The fuge was cleaned and returned to the stand.
The substrate was returned and filling it with clean change water began.
The cheato that showed signs of cyano growth was removed and separated from the good stuff.
The live rock and the clean (I hope!!) cheato was placed back in the fuge along with one hitchhiker crab and two hitchhiker urchins.
We had prepared to run an HOB filter on the fuge to polish the water from any residue that might have been in the substrate but everything appeared clean and clear. So we started the return pump and things stayed clear looking.
We kept everything in salt water and nothing had a chance to begin drying...... so we're hoping that we don't experience any type of mini-cycle. All in all it has been over a year since we installed the fuge and this was the first big cleaning that it has received.
