Lightsluvr's 340G Upgrade

I don't see the Duncans, were they just closed up during the pics?

No, they were in just about every picture:

Look on the front of the LR, right side:

And on the top of the center island, right side of the photo:
FTS0930D.jpg


They're both doing well!

The Sun Coral colony wasn't too happy with me, because I turned off the closed loop to take pictures. What movement you see in the photos os all MP40W!

Apex graphology

Apex graphology

Here is yesterday's 24 hour graph of tank pH (upper graph) and CA reactor effluent pH (lower). I am happy with the swing of tank pH which has narrowed since I began to run frag tank lights in the early morning hours. The CA Reactor pH is interesting to watch as the CO2 solenoid is turned on and off by the Apex controller. When the pH reaches a high of 6.7, CO2 is injected until the effluent falls to 6.41. This keeps effluent in the optimum range for producing ALK and CA from the media.

Sounds like you have the CA reactor figured out. I think I would need a few night courses to figure it all out though.

This is cool.
 
This is cool.

Thanks, Greg.

I am realy enjoying the Apex as I learn more about what it can do... They are coming out with some updates and new hardware that will be really exciting...

I've not posted in a few days, as I have been battling STN on a couple of my SPS. I lost one encrusting colony within three days. The blight spread to an adjoining colony, but seems to have stopped. I cannot identify a cause.

My CA reactor overshot on ALK (peaked at 12.5), but it would have been a gradual increase, so I doubt that was the cause. Other parameters are spot on: CA is solid at 420; MG is 1350-1400. PO4 is .20.

No other coral anywhere in the tank seem to be affected. In fact, I am still seeing good growth on SPS elsewhere in the tank.

I guess crap just happens...

Sorry to hear about the loss!
Never discount AEFW! Those suckers could have been somewhat dormant, or kept in control by your wrasses then spawned like crazy into a mini colony which began to feed on your coral. Keep a close eye out!!!

I examined the coral for eggs and found nothing. I broke off a piece of the colony that was undamaged and placed it in my frag tank. It continued to slough tissue and died. That's why I am thinking STN rather than AEFW.

Thanks for the tips... I'm watching the area closely to see if it spreads to nearby montis or birdsnest.

Dang George, this is irritating :mad2:

Which corals?

I know it's what makes this hobby a challenge, that it's always something... but this SPS thing is really baffeling.

Really sorry.
 
Don't loose heart, in my opinion some STN can be a blessing. I have several colonies that no longer have living tissue connecting the branches so when one branch decided to RTN the death signal never made it through to the rest of the colony and I just lost the one branch. STN is how reefs get built and I wouldn't worry about it too much if it is in fact STN. I find that they tend to come around but if it looks like it is spreading to quickly then cut off a branch as insurance. Good luck.

Thanks all for the thoughts...

The problem seems to have resolved... I may never know what precipitated it...

Time to go do a water change...

This afternoon, time permitting, I am going to break out the PAR meter and get some readings in the tank.
