Index of Species
This is a chronological log of all measurements, changes, and observations
relating to this tank. Also check out the coral growth log for the Acropora Challenge.
- 1993 log entries
Add algae blennie, Salarius fasciatus
- Changed actinic bulbs, replaced failed QuietOne pump. Water
testing: S.G.=1.0205, temp=77.5, alk=7.0 dKH, pH=8.1, nitrate=0,
- Missing log entries
- Did water testing to fill out forms for Acropora Challenge.
S.G.=1.026 (high!), nitrate < 0.25ppm, pH 8.2 (a little low, should
add more buffer & kalkwasser), alk=7 dKH, Ca+ = 500ppm (this
is surpisingly high; good thing I've quit using CaCl2), temp 78.
Following testing I dropped the salinity a little by removing
a gallon a saltwater and replacing with freshwater, and added
more buffer and kalkwasser. Lobophyllia seems happier an hour
- Received coral fragments of Acrpoora microphthalma, A. elseyi,
Pavona cactus, and Montipora digitata. Also added 4 very small
limpets and 8 astrea snails.
- Attached new coral fragments to rocks with rubber bands. Shot
video pictures of them with rulers to document growth. Tested
pH = 8.3, alk = 7.5 dKH, salinity = 1.026 S.G. (still too high,
will have to adjust)
- Pavona coral came loose from rock. It landed near the elegance
coral, but I don't think they touched. I replaced it, wrapping
rubber bands more firmly this time. If it slips again, I will
find marine epoxy. I added another powerhead for greater current,
but it was actually too much (yellow polyps and elegance were
unhappy, tang was even skittish), so I shut it off. I think I
need more current, but a less powerful PH than the one I used.
- Added a Tridacna crocea clam. Also finally got a wavemaker,
currently set to randomly switch 3 power heads at 1 minute intervals.
- Now dosing with Combisan instead of separate iodine and strontium
additives. The bottle says to start at a drop per gallon per week,
and work up to a final dosage of 2-3 times that; that works out
to about 1 teaspoon for my tank/week.
- Dosing the Combisan at 1/2 teaspoon every other day now.
- Added 3 Astrea tecta snails, Cladiella soft coral attached
to live rock.
- Added mandarin fish. Used marine epoxy to glue down the coral
fragments, which weren't staying in place well enough with rubber
- Performed a 6 gallon water change.
- Tests-- pH 8.4, alk 6.0 dKH, Ca+ 516 ppm, Nitrate < 0.25ppm,
S.G. 1.026, temp 78F
- Discovered something has been attacking the Pavona cactus coral.
Numerous small chips are missing from the upper edges. A number
of them are littering the live rock below the coral. Don't know
what's doing this.
- Replaced the almost 2 year old MH lights with new bulbs. It
is much much brighter, and somewhat yellowish as well. Hopefully
the bulbs will soon stabilize and be less yellow.
- Water tests: pH 8.4, temp 77.2F, S.G. 1.026, nitrate < 0.25ppm,
Calcium 567ppm, total alkalinity 7.56 dKH.
