Day 6 results and will be testing day 7 in about an hour... Day 7 is going to be my last daily test as I will be hitting water change time anyway.
Nitrate: 0 PH: 8.4 (I need to get up early an give an am reading for this, its on the "todo") Am & Nitrite: 0 Observations and other info: -Largest clown is acting very odd for two days, it does not want to swim at all and I thought it would be dead tonight but all is well so far. It does not seem hungry either, I have no idea here. I have had all three for a week and a half or so and the other two seem normal. I will update. -Increased salinity by .001 SG last night over a two hour period, and will match whatever evaporation has gotten it to by tomorrow when I do a water change. My assumption is that I will be hitting 1.025 by then and allowing up to a max of 1.026 between top-offs thereafter. -I will be switching out carbon and further decreasing its flow this weekend. Does anyone know off hand if carbon will 'catch' hydrogen sulfide, before I have to go do a bunch of chemistry research? (Just in case here) -very low algeal growth and bryopsys remnants seem to be gone. (turbos and no nutrients is best assumption here because alk is not that high) -Have decided not to risk running GFO or AO since I cannot get a positive test. There are too many posible detriments I see from reading Holmes-Farley's articles on the two. Plus, I may drip a light solution of Kalk top-off to bind any up that may exist outside of the accuracy of the liquid kits being used. I need to eventually get in on that meter you told me about Jon, but later. |

Off hand, the other tank (the 8 gal Biocube) tests out at 20 now without those stupid bioballs in it.
Also, since this is a reduction I double checked the kit in case it is going bad. I have some LR curing in a bucket with a Rio 1700 circulating it (yep warm) and it has not seen a water change- it tests off the chart, so I know that the kit will still read red. |

Does anyone know off hand if carbon will 'catch' hydrogen sulfide, before I have to go do a bunch of chemistry research? (Just in case here) I would expect that activated carbon would not bind H2S, as its structure is actually quite similar to water- and it does not have large nonpolar constituents. Have you experienced any odor from your unit? I would expect that the H2S will either be released as a gas, or would form at a pace slow enough that it would be able to dissociate in solution to HS- and a weakly acidic H+. If the latter is the case, be sure to watch your pH and alkalinity carefully. |

No odor, H2S is just a concern of mine with the rdsb over time. If carbon cannot do anything about it, I don't think I have too much of a reason to run carbon. At least not as much as I have been, going to cut flow and volume of carbon in half each.
Day 7: Nitrate: 0 |

Day 10+: (morning results)
Nitrate: 0 PH: 8.2 (0.2 shift from pm reading) -seems good to me! |

Remember pH scale is logrithmic so .2 is a good sized swing. I try to keep mine at .1 FWIW I tested my nitrates today (1 week since the last water change) and they are somewhere between .2 and .1 ppm. Its getting harder and harder to see the colors.

Good point. Maybe I should go back to running a 'fuge/sump light overnight. I am glad still that the PH is on the higher side with a 0.2 swing than being on the low side with the same swing, even if my 0.2 represents more variability though. Would you disagree?

I have given up trying to make the pH be high enough all I do is try to reduce the swing. I think an inverted light schedule goes a long way to keep your pH stable.

Finally here are the pictures. I'll warn you that this thing is UGLY, but it works just fine.
IN - Supplied by a Maxi Jet 1200, this 1/2" flexi-tube comes from the last section of the sump to give the cleanest supply water.  OUT - 3/4" return line. Straight slope back to the sump. Having the end of this line underwater, and a formerly long line backed up the bucket a bit.  UNDERWATER EPOXY CLOSE UP - I also used PVC primer on the bucket after roughing up the area around the holes I bored, both so that the putty like epoxy would bond better to the bucket.  SIDE SHOT - The mild algae in the line suggests some phos but that has tested 0 as well.  TOP VENT & NO SALT CREEP SOLUTION  This was needed so that the bucket would drain properly.
