    Trachyphillia g. ?

    Define progress... Part of the problem though with 'solving' the pH 'issue' if it is related to gas exchange, is that your atmospheric levels of O2/CO2 during the summer and winter may be skewed due to having the house closed up, skewed toward an increase level of CO2. Another part is the...

    Trachyphillia g. ?

    So you're saying that reefs don't fluctuate .2 points daily or slightly more (8.0 - 8.4)? I'm not perpetuating any 'falsehoods', the bottom line is that reefs do fluctuate, are you going to say that temperatures don't fluctuate daily on the reefs, too? In one of my first acro tanks, I used kalk...

    confirm id's please

    I'd also through in the mix that the last pic might be A yongei... As far as the Monipora goes, that is awesome, I'm not in front of my Veron books, but danae, nor verrucosa do not, if my memory recalls, exhibit digitate growth forms. But then again, Montipora are really hard to ID properly...

    Trachyphillia g. ?

    I support that position by simple logic and experience. Sure it'd be great to not have any swing whatsoever. However, naturally the pH swing as CO2 enters the water during night due to respiration and the absense of photosynthesis. During the day, it is the opposite, CO2 becomes depleted due...

    Trachyphillia g. ?

    As long as the pH swings are within the range, you'll be fine. Why would you need to be concerned, if your animals aren't stressed?!? Sure calcification may not be occuring at the optimal pace.

    Trachyphillia g. ?

    You've got T5s, so it may be as simple as adjusting to your light. What lighting was it under at the LFS? Trachy's do not like a lot of direct light....

    Trachyphillia g. ?

    Part of the problem is your ID. In the first picture, there is a trachyphillia and a differeent species either scolymia or symphillia... not sure which. Those don't expand too much, even compared to the trachyphillias.

    question about bio balls in skimmer

    What pump are you using? Sounds like a pump issue, not a skimmer issue, your 800 should have 22 bio balls in it, do not take any out! You need at least a pressure rated iwaki 40, or Blueline 40. I won't run anything less though than a Blue line 55 on downdrafts of this size.

    What was your salinity?

    Trachyphillia g. ?

    Also, most PO4 test kits are crap. If you're interested in testing for PO4 you need either Hanna or Deltec/Merck. Your alk is way too high.... I've got tanks packed with clams and sps and run my alk at 7 dkh. But just as with sps, PE isn't an indicator of health. There are many reasons that...

    Trachyphillia g. ?

    Why would a pH swing be stressful?!? That's not accurate. It swings on the reefs. Unless your pH is swinging from less than 7.8 to more than 8.5, your fine.

    NSW mag is ~1300 ppm... What are the alk and ca levels of the salt?

    question about bio balls in skimmer

    Leave the bioballs in the skimmer, unless you don't want your skimmer to skim. A wet/dry and a downdraft skimmer are two different animals. You need a pressure rated pump to run the skimmer. They are some of the best skimmers made.

    help me identify this bad @$$ tort

    I am 100% certain that this is the ORA Blue Tort. I've several straight from ORA. What lights do you have them under? I've found that under 10K, the blue is.... blue. However, for another system I'm running Radiums on HQI ballasts, and while there is a lot of blue, the inner branches are...
