    Algae Scrubbers

    Here's another paper showing algal exudates are allelopathic to corals: http://www.pnas.org/content/108/43/17726

    Substrate

    My favorite is CaribSea's Fiji Pink but any coral sand with a grain size between .5mm and 1.5mm I would be happy with.

    Algae Scrubbers

    Here's what he said ". . . for reasons unclear, the algae has never outgrown the filter and has never had to be removed or harvested, . . ." Here's the link to Palletta's review of Leng Sy's Ecosystem in 1997 Volume 14 Seascope if you want to read his whole article. The .pdf has all four issues so you'll need to scroll through them to get to the summer issue it's in. Here's the best example I have: Initially Calurpa growth was pretty robust and was a fair amount was harvested from the two ~40 gallon refugiums 3 or 4 times the first two years. It was harvested only one more time after that and the last two years even though there was a fair amount that showed some growth with new runners overall there wasn't any significant changes in volume and none was harvested. And here's a video of the system.

    Automatic feeders

    Thank you!

    Automatic feeders

    The feeding tube creates a venturi effect that sucks the food directly into the return pump intake. You can see a 90° elbow at the bottom with the intake side of it pointed down. This elbow is attached to the intake of the return pump. The slots in the side of the tube are cut at an angle to help crate the venturi or whirlpool swirl that keeps the food from building up on the side of the tube and rotting. The bottom of the tube is sealed with a peice of acrylic so all the water has to go through the slot on the side. The slots I cut with a cordless circular saw held at a bit of an angle but it would be easier I think to cut them on a table saw but I imagine could be made with a 1/4" drill and a small handsaw to connect the drill holes. I have tried dumping food into a sump above or next to a pump intake and a lot of it does not get sucked into the pump. This will end up rotting and can smell pretty bad and using a feeding ring in the sump doesn't prevent it from happening.

    Not surprised at all. Micheal Palletta back in the mid 90's observed the same thing when looking at Leng Sy's "Ecosystem" method and I've seen the same thing every time I've put macros in a refugium. My guess is you've been seeing a fairly decent coral growth recently (if you haven't completely stripped out PO4). Before you go through the work of installing an ATS I'd suggest you read these papers on the competative and antagonistic roles corals and algae have, for both nutrients and microbial processes: Algae DOC: https://peerj.com/articles/108/?utm_source=TrendMD&utm_campaign=PeerJ_TrendMD_0&utm_medium=TrendMD https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0027973 https://www.nature.com/articles/nmicrobiol201642 Carbon dosing kills coral: https://www.int-res.com/articles/meps2005/294/m294p173.pdf https://www.int-res.com/articles/meps2006/314/m314p119.pdf

    Automatic feeders

    I'm a huge fan of Ehiem's single hopper autofeeder. I'll use one or two on systems with NLS 1mm and 0.5mm pellets. With fish like Lyretail Anthias or Vanderbilt Chromis I'll mix ZoPlan and Reef-Roids can be added for corals. A trick I learned with Elvis, my 25+ year old Sailfin Tang since he was getting pretty fat compared to his tank mates was to use the 0.5mm pellets in two autofeeders synchronized to feed at the same time, It takes longer and is more work for him to go around and gobble up the pellets giving the other fish more time to eat and helps keep his weight down. I also use a "feeding tube" attached to the input of return pumps to broadcast food throughout a tank so one fish can't dominate an area where food is dumped.
  8. My guess, since salinity of brackish water is going to be variable depending on rainfall and tides a 25% change in salinity over a 12 hour period wouldn't be a problem.
  9. Fascinating Pocillopora damicornis' genome is so unique. A coral's innate immunity to bacteria is certainly a deciding a factor in it's response to changing environmental conditions. Research like Wright's paper presented at C4 2016 and Bock's paper show significant differences in the immune response between genotypes within a species. Understanding which genes provide inhanced immunity and looking for those genes in other species/genotypes would go a long way to selecting and growing corals for restoring reefs.

    Rimless 180g "2nd child"

    The Sun System's PAR meter is a rebranded Apogee MQ-210 marketed to the hydroponics industry. It will read be about 10%-15% low on the blue spectrum.

    Austin Boil Notice

    Keep in mind there are quite a few water utilities in the area. At least some are using wells which I would think would be unaffected and some of the private utilities are definitely better at filtering their water. Those who have posted TDS reading it would be helpful to also post the water utilities water source to get some idea of why there's such a wide range of readings.

    Water pik to clean coral

    Pretty cool! Anyone using a waterpic definitly needs to heed the warning about it removing tissue. I've read research papers where waterpics are used to remove all the live tissue from coral skeletons for experiments. I also have the same concerns Stoneroller mentioned. I QT EVERYTHING unless I have a personal history of a system and know ther've been no problems or additions in a very long time.

    How long to keep aggressive tang in time-out?

    If they've already been together that long I would be surprised if you have any problems. They mature around the 5 year mark and when an aquarist gets a group all the same age that's when problems can arise if crowding hasn't been an issue already.
