It's time for another water change

Rate this Entry
I've been performing 50g water changes every 4-5 days on the system, and observing the corals for indications of improvement. There are still a number of corals that need to regain their former glory, but overall things look pretty good.

The calcium reactor needs new media badly and it should arrive any day. I've been supplementing alkalinity with baked baking soda.

This acan in the Anemone Cube has been a boring brown color with only some orange around the front leading edge. The change from running a very clean system with the eventual overdose of bacteria really played havoc on some of the corals pigmentation, and as they heal the rainbow-like series of colors showing up now almost make them look like designed hybrid corals. Not my intention of course, but it has made the healing process interesting.

This blue ridge coral has been growing over the rockwork for the past 10 months. It started from a two-lobed piece in the center.

Another pigmentation change. Look at this cyphatrea, with green one the left edge, but this beautiful blue area between the pink polyps. It looks like I painted it.

Two acroporas that survived the ordeal are still regaining color. Polyps are extended, which is a good sign.

The smaller chalice on the right in this next picture was so pretty before. Now it's brown, and receding. Ugh. Hoping it will turn around.

More green is appearing on the montipora coral.

This cactus pavona is regaining its color. It was quite pale for a while, losing almost all its pigmentation.

These guys are doing well. Even that aiptasia that I need to get rid of.

While two acan fraglets have perished, these two look great.

And the Bubble Tip Anemones seem very happy and vivid.

For a long time, this one coral was a boring brown blob. It's turned purple and I'm not about to complain one bit about that.

    Wow, some great color changes from those corals. The silver lining of this ordeal I guess? I was wondering, have your nitrates crept up at all since you've stopped the pellets, or maybe your large water changes have kept them in check? Later down the road do you forsee running your pellets again? With or without dosing bacteria? Or are you going to try another route?

    I'd planned to go back to running biopellets and prodibio as before, just at the right ratio this time.

    50g water changes on a 450g liquid volume system isn't large, but since I'm doing them often, it does add up. I've done about 300g's worth of water changes in the past 6 weeks or so.

    The goofy colors are interesting, but historically when I watched corals go through the rainbow they died. My assumption is that with how I was running the system all this time, the colors I was seeing were results of the total bacterial load of the system, and now that that has been altered greatly, the colors are shifting to adapt.

    I do have one large chalice that is doing quite poorly right now. I think it got damaged by a fallen pump I was about to test, but that's just a guess. Seeing exposed skeleton patches in the center is disheartening, but quite a bit of it still looks to be okay so far.
