    Need some advice on a T5 fixture

    Jason, I was in the same bad electric bill situation as you before, until I installed solar panels. It effectively rid most of the top tier charges, you feel good that you are not damaging the earth as badly with this hobby, and it is a good showoff in the neighborhood. Funny thing is that this...

    Has anyone experienced this before: six line killing mystery wrass

    The mystery is still hiding under the same rock, not coming out for food :(. I am thinking more about it, could it be that she is getting too old to reach the end of the candle, and the sixline just smelled it? The mystery was very much full sized when I got her 3 years ago. Sad to think this...

    Has anyone experienced this before: six line killing mystery wrass

    I have a mystery wrass who is full sized when I got it at the beginning of this hobby 3 years ago, and she is close to 5" now. For those who have seen my tank, you know I also have a six line wrass which was pretty big. Recently, the six line grew even more, and it is between 2.5" and 3" now...

    Royal Exclusiv Vertex Alpha 170 Cone Skimmer

    The red dragon pump that comes with the alpha skimmer actually says Bubble King on it. I went through so many skimmers, and I think I will stick with my Alpha 200 for many years to come. I would not say it until I used one.

    DBTC: The chalice previously known as Tong's Miami Hurricane, but is more likely a mummy eye or something similar...

    Yea, the color on this piece shifts a lot. At one time, it was just like what Jason described, green with pink eyes. So I checked with the original seller (Jose with RC handle name guppy0210, who has a lot of good stuff in his little tank), and he confirmed that it is miami hurricane, and he...

    Foam around all pumps, WOW!

    I put on the foam cover over the vortechs when I first got my sea hare, but I have to take them off everytime when I feed, or most of the food got sucked onto the foams. I eventually gave up and don't put on the covers anymore. Cross my fingers that the sea hare will not get into the vortechs.

    pH probes, HUGE discrepency

    But even if you calibrations were off due to above reasons, shouldn't the delta between the two be more or less the same if your ph is not swinging wildly? You said sometimes they differe by 0.1 and some other time differ by 0.8, I would be worried about the readings.

    Recommend an Electric Generator

    I have a Honda EU3000i and love it. Quiet, long lasting, and even looks good. But it is much heavier than I expected. So i installed wheels on it. Now I can roll it around, but lifting it into trunk is still a back breaking risk, so I might never take it onto a trip :(

    DBTC Zombie Sea Hare

    Hey Garvin, I gave the sea hare to Arnold around 7pm, and you are probably on your way picking it up now. Again, thank Garvin for the sea hare, and thanks Arnold for helping me passing it back.

    DBTC Zombie Sea Hare

    Hey Art, Thanks for your description. I was wondering what happened to the sea hare, and it is good to get a confirmation of the behavior from you. When I first got it from Gavin, it was eating algae really fast, and it slowed down significantly in a couple of days. Probably due to it was...

    DBTC Zombie Sea Hare

    Hi Gavin, The algae in my tank is not going away as fast as I thought, so I bought a small sea hare today that I plan to keep for a while. Unfortunately, I do not have plan going up to SF in near future. If you are coming down, please let me know 2 to 3 days ahead of time so I can fish out...

    DBTC Zombie Sea Hare

    Hi Gavin, The sea hare is working slowly on my algae, and it might take a while to have everything cleaned. I can give it back to you to work on your HA, and I can get a sea hare from another friend soon. LMK and thanks.

    Please Help Us Track Down These THIEVES

    Sorry Robert to hear something like this, I can't believe people would steal corals. Ian, even though the pic is of the same frag, it was posted on 10/3. I think the person just grabbed Robert's pic.

    LED actinic for a 70G cube

    Yep, I am not kidding when I said the pop hurt eyes. But once the MH turns on, most of the pop is washed out, which is what I wanted.

    LED actinic for a 70G cube

    Thanks Mike. I think for constant current driver, there is a voltage range it can support. For the driver that I used, it SHOULD support between 3v to 30v according to the spec. Given each LED takes about 3.5v at 700ma, it should be able to drive anything between 1 LED and 8 LED. If you go...

    LED actinic for a 70G cube

    Thanks Phong. One of the bad things about this hobby is your tank is always too small doesn't matter how you upgrade :D.

    LED actinic for a 70G cube

    Thanks Jar. Here are a couple of actinic pics. Somehow the camera cannot capture the neo pop of the actinic light. In person, the neon orange on fungia is so bright, it actually hurt eyes if you stare at it for a little while, which I do often after I install the actinic (I am not kidding)...

    LED actinic for a 70G cube

    I am getting tired of posting these DIY threads, so this will be my last one. It is for a 70G (30"x30"x18") starfire ringless tank, and it is fitted in a DIY hanging light box with a Lumen max elite MH reflector and the box is cooled by 4 120mm fans. Total of 24 royal blue LEDs are mounted on...
