  1. So I went home for Christmas and my reef keeper decided to stop working, wouldn't read the temp or the water level. So the Heater and ATO never came on. I had turned my apartment heat down to 60. I came home to the smell of death, my tank was 60 degrees and missing 5 gallons of water. Lost all of my livestock, even macro algae. So I cleaned and cooked my rock for a few months while i was in the hospital for 28 and recovering for the next 28 or so. Got new live stock and going to do a softies tank this time. Got the reefkeeper all setup and some livestock. Guess what the reefkeeper started crashing on its own. Tank got down to 70 but thankfully nothing died. I decided not to trust it with anything but the lights. I add water on my own and the heater is plugged into the wall. I have 2 thermometers to check. Should I just got low tech or save my pennies and buy an apex? I dumped atleast 750 into the reefkeeper and am ready to give up on it. But 550 for the base model is alot to spend. Low tech doesnt seem to bad. I might be able to sell some of the modules and get some of that back.
  2. FS-a whole s#!t ton of stuff...

    Do you have a SL2 for the reefkeeper?
  3. the number refers to the diameter in 8ths of an inch. so t5 is 5/8ths. t8 1in, t12 1.5in. Overall in aquariums (and industry) it boils down to efficiency. t12s were first on the scene, fairly low power and inefficient large diameter does confer an advantage over t8s. t8s are widely used for lighting but are low power but more efficient that t8s. T5s are tricky. there are two types of t5s t5 and t5ho. t5 is just a slimmed down t8 not a good or a bad thing depending on application. t5ho however emit a good deal of light (and heat) but in a very small package their small diameter allows them to have a good reflector that reduces re strike (thus increasing efficiency) in a small package. t12 are end of life. t8s are near theirs, t5s are in their mid life. I buy around 500 t5s a year for a building. pretty much any new fixture is going to use t5s while older ones use t8s. anecdotally 1 t5ho is about as bright as 3 t8s
  4. Too powerful LED's?

    you could put a screen over the light short term to block some light. such as window screeen or nitting mesh.
  5. skimmer would be best. there are some decent HOB skimmers out there. live rock in a canister is kind of meh, would be better off putting carbon or something useful in it. DSB discussion is always interesting, i like the look but end up siphoning alot of it out over a year or two. Airstone skimmers are alot quiter than venturi designs ( i use a cpr skimmer with air stones instead of the venturi and it works better and is far quiter). I havent tired other skimmers so i cant comment on them. I dont think that UV sterilzers have a real place in a healthy system, this is opinion and not fact.
  6. Cleaning pumps, etc...?

    straight or 50/50 with water. I soak 1-2 hours, more is better. Costco is the cheapest place to get it FYI
  7. MEN

    http://reefkeeping.com/issues/2007-09/eb/ A month I think is about good. I had some in my tank and wiped them out with a few dips of potassium permanganate. Its the nuclear option but it worked. Now one of my motni colonies that was affected is slowly wiping out a zoa colony.
  8. Chaeto turning white?

    is it touching a heater or light? that can kill it too.
  9. Need Help with led lighting

    Check your wiring and soldering first. that driver should handle around 6 leds no problem. Thats also a dim-able driver so make sure that is wired correctly.
  10. Bubbles on Zoa Frag

    looks like bubble algae
  11. Letting the corals grow

    I have experienced some weird battles. I have intervened on a few. Here are some i have had: GSP encroaching on zoas, gsp dies back some, then grows around the base and sides of a few zoas Frogspawn 'killed' a sps frag that fell into it, flesh was gone skeleton, was white sps looked like nothing happened within a few weeks acro and encrusting monti grew up against one another both had a 1-2mm band of dead flesh, both started growing a 'wall' along the line encrusting monti encrusting over zoas acro damaging pollicora with tentecales By far acros seem to be the most deadly. I have watched sweepers from galaxea hit soft corals and the softies recover within a day or two. with acros it almost always involves some death.
  12. set it to auto off at 5:00pm on at 5:05pm
  13. A very interesting read on Clams: http://www.sciencedaily.com/releases/2014/10/141002123728.htm Evolution in extreme environments has produced life forms with amazing abilities and traits. Beneath the waves, many creatures sport iridescent structures that rival what materials scientists can make in the laboratory. A team of researchers from the University of Pennsylvania and the University of California, Santa Barbara, has now shown how giant clams use these structures to thrive, operating as exceedingly efficient, living greenhouses that grow symbiotic algae as a source of food. This understanding could have implications for alternative energy research, paving the way for new types of solar panels or improved reactors for growing biofuel. The study was led by Alison Sweeney, assistant professor in the Department of Physics and Astronomy in Penn's School of Arts & Sciences, and Daniel Morse, professor emeritus in UCSB's Department of Molecular, Cellular and Developmental Biology and Director of its Marine Biotechnology Center. The team also includes lead author Amanda Holt, a postdoctoral researcher formerly at UCSB and now at Penn, as well as Sanaz Vahidinia of NASA's Ames Research Center and Yakir Luc Gagnon of Duke University. It was published in the Journal of the Royal Society Interface. "Many mollusks, like squid, octopuses, snails and cuttlefish," Sweeney said, "have iridescent structures, but almost all use them for camouflage or for signaling to mates. We knew giant clams weren't doing either of those things, so we wanted to know what they were using them for." While the true purpose of these iridescent structures, cells known as iridocytes, was not known, the team had a strong hypothesis. Like neighboring coral, giant clams are home to symbiotic algae that grow within their flesh. These algae convert the abundant sunlight of the clams' equatorial home into a source of nutrition but are not particularly efficient in the intense sunlight found on tropical reefs; sunlight at the latitude where these clams live is so intense that it can disrupt the algae's photosynthesis, paradoxically reducing their ability to generate energy. The team members began their study hypothesizing that the clams' iridocytes were being used to maximize the usefulness of the light that reaches the algae within their bodies. They were first confounded by the relationship between these iridescent structures and the single-celled plants, until they realized that they had an incomplete picture of their geometry. When they made more precise cross sections of the clams, they found that the algae were organized into pillars, with a layer of iridocytes at the top. "When we saw the complete picture, we understood that the pillars are oriented exactly the wrong way if you want to catch sunlight," Sweeney said. "That's where the iridocytes come into play." The team relied on Amanda Holt and Sanaz Vahidinia to model exactly what was happening to the light once it passed through the iridocytes; the degree of disorder within these cells bore a resemblance to structures Vahidinia studies at NASA: the dust of Saturn's rings. Their analysis suggested that the iridocytes would scatter many wavelengths of light in a cone-like distribution pointing deeper into the clam. Red and blue wavelengths, the most useful to the algae, spread the widest, impacting the sides of the pillars in which the single-celled plants were stacked. To test this model, the team constructed fiber optic probes with spherical tips the size of an individual alga. Threaded through a section of clam flesh alongside the native algae, this spherical probe was able to detect the angled light scattered by the iridocytes, whereas a flat-tipped probe, only able to sense light shining straight down, detected nothing. "We see that, at any vertical position within the clam tissue, the light comes in at just about the highest rate at which these algae can make use of photons most efficiently," Sweeney said. "The entire system is scaled so the algae absorb light exactly at the rate where they are happiest." "This provides a gentle, uniform illumination to the vertical pillars consisting of the millions of symbiotic algae that provide nutrients to their animal host by photosynthesis," said Morse. "The combined effect of the deeper penetration of sunlight -- reaching more algae that grow densely in the 3-dimensional volume of tissue -- and the "step-down" reduction in light intensity -- preventing the inhibition of photosynthesis from excessive irradiation -- enables the host to support a much larger population of active algae producing food than possible without the reflective cells." Mimicking the micron-scale structures within the clam's iridocytes and algal pillars could lead to new approaches for boosting the efficiency of photovoltaic cells without having to precisely engineer structures on the nanoscale. Other alternative energy strategies might adopt lessons from the clams in a more direct way: current bioreactors are inefficient because they must constantly stir the algae to keep them exposed to light as they grow and take up more and more space. Adopting the geometry of the iridocytes and algal pillars within the clams would be a way of circumventing that issue. "The clam has to make every square inch count when it comes to efficiency," Sweeney said. "Likewise, all of our alternatives are very expensive when it comes to surface area, so it makes sense to try to solve that problem the way evolution has."

  14. Making salt water from scratch

    Its possible. probably not worth it. the guy saying you need a $1k balance is being dramatic. I load rifle and pistol rounds on a $60 dollar scale and it is accurate and precise enough that I shoot tiny little groups and have never been hurt. You can find the various reagents if you get creative. lab grade chemicals are expensive and not what you need/want. Food grade should be fine and a lot cheaper. Unless you are making a ton of salt it would still be easier and less hassle just to buy it.
  15. Aqua Clear 70?

    the filter is fine for media, not so great for water flow. you will still need some kind of power head. There are many options for power heads and the pros and cons can be debated with no end in sight. A simple, cheap , reliable solution is a maxijet or aqueon powerhead. More expensive options exists and their benefits can be debated. I have run aqueon power heads on a wave maker and was happy with them. I now run mp10s and am extremely happy with them, the over all difference in 'tank quality' is not apparent but aesthetically the MP10 is nicer.
