Peer Review database in the hobby?

[Pankney72]

Hey all. I’m a guy with a science (biochemist/cell biologist) background and I’ve been reefing with a pretty minimalist system for quite a while now. That said, I’ve finally got the resources to do a custom build 250 gal before I move for work, and my question is this.

I’m sure peer reviewed stuff for our hobby is out there. @Humblefish , @randyBRS , and @Randy Holmes-Farley mention studies in their advice but I don’t usually see the references.

Where do you guys get your science from? Any good newer books out there like The Conscientious Marine Aquarist? I want to add bells and whistles to my new tank but I want to make sure they will add QOL to my system. Thanks a ton!

(by the by minimalist is my moderately stocked 125 mixed reef with good LEDs, skimmer, filter pads and religious water changes.)

Personally I just skim the studies on google scholar some great studies on chemistry in reef aquaria and trace elements in salt water. I find every book I see is outdated on taxonomy and modern lighting, filtration, and sources for livestock. If you have research credentials at work/school you can normally access the studies for free through your institution.

 

[NoahLikesFish]

i learn from experience and i use basically the same method you would in the 90s/2000s except i dose seachem & i run leds. no skimmer, filtration, water changes, just biofilter and flow can work miracles.

 

[NoahLikesFish]

i read on some stuff concerning like fish biology and reef biology and stuff but i just keep it simple and it works well. walstad's book on the planted aquarium is good for learning what makes algae tick & paul b's book does a good job talking about diy & its funny.

That’s what I typically do, and I do have the access through my employer. Google scholar kicks the teeth in on other search engines haha. To be honest I posted this because I was looking at UV sterilizers for ich management but I couldn’t find a paper with information that would be transferable to a home system.

 

[jcolliii]

GS is pretty good, but if you have a large local university nearby, the databases that are paid for by some university systems will directly link a TON of full text stuff that GS won't. You can also sign up for an account on Research Gate - lots of folks share their work on that site. Also, if you find an article on GS that you want or need, email the lead or second authors - they usually have a pdf that they can share.

 

[flagg37]

You’ve got all the peers needed to review your stuff right here.

I use Google scholar to find what I need, then swap over to our systems for full text. Thank you for the quick response!

Try searching under mariculture journals. They have much more funding than reefing.

Imo the biggest hurdle to us hobbyist is not the lack of research (there are plenty) the issue is that hobbyist equipment is less transparent.

For instance, we know from some literature that ich can be reliably killed with exposure to UV radiation above 300000 uws/cm2. However there is no way for us to know, or measure that a given hobbyist equipment produce such irradiation.

I was going to say the same thing aquaculture\mariculture, using the same equipment just on a bigger scale.

 

[N.Sreefer]

I would say recirculating aquaculture but not mariculture or flow through aquaculture. We don't have the advantage of exchange with the ocean.

Exactly! I’m a bit of a purist in translating research into something applicable on my scale. Knowing that a battery that produces the UV fury of a thousand suns kills ich or some other industrial/commercial grade equipment equivalent doesn’t necessarily help me make purchase decisions for a 250 gallon home tank

This company sells various sized units commercial and smaller, they used to have data sheets, but I noticed the pages weren't found.
The company used to be Aquatic Ecosystems, https://pentairaes.com/. I know they used to do local display type installations in Florida so they were knowledgeable in smaller scale operations.

Coral-excavating sponges are the most important bioeroders on Caribbean reefs and increase in abundance throughout the region. This increase is commonly attributed to a concomitant increase in food availability due to eutrophication and pollution. We ...

Aura-biomes are present in the water layer above coral reef benthic macro-organisms

Aura-biomes are present in the water layer above coral reef benthic macro-organisms - PubMed

As coral reef habitats decline worldwide, some reefs are transitioning from coral- to algal-dominated benthos with the exact cause for this shift remaining elusive. Increases in the abundance of microbes in the water column has been correlated with an increase in coral disease and reduction in...

Establishing a Healthy Microbiome in a New Aquarium Using Live Rock

About this article This article describes an experiment documenting the effects of live rock in a newly established aquarium. While I’ve tried to tell the story as briefly as I can, it’s the story of a month-long study of replicated tanks, with analysis of both water chemistry and the microbial...

Elemental Analysis of Skimmate

Elemental Analysis of Skimmate: What Does a Protein Skimmer Actually Remove from Aquarium Water?

Department of Chemistry, The Pennsylvania State University, University Park, PA 16802. The chemical/elemental composition of skimmate generated by an H&S 200-1260 skimmer on a 175-gallon reef tank over the course of several days or a week had some surprises.

Bacterial Counts in Reef Aquarium Water

Bacterial Counts in Reef Aquarium Water: Baseline Values and Modulation by Carbon Dosing, Protein Skimming, and Granular Activated Carbon Filtration

What are the bacteria populations in the water column of reef tanks, and how does that value compare with bacterial counts in authentic reef water? Does carbon dosing indeed increase water column bacteria populations (i.e., is growth carbon limited)? Does mechanical filtration (protein skimming...

Amino acids a source of nitrogen for corals

Uptake of dissolved free amino acids by the scleractinian coral Stylophora pistillata

SUMMARY. This study was designed to assess the importance of dissolved free amino acids (DFAA) as a nitrogen source for the scleractinian coral Stylophora pistillata. For this purpose, experiments were performed using 15N-enriched DFAAs, and %15N enrichment was measured both in animal tissue and...

Urea a source of nitrogen for corals

Urea uptake by the scleractinian coral Stylophora pistillata

Urea can be one of the major sources of nitrogen for phytoplankton, but little is known about its importance for corals. Experiments were therefore de…

Diazotrpophs a source of nitrogen for corals

Diazotrophs: a non-negligible source of nitrogen for the tropical coral Stylophora pistillata - PubMed

Corals are mixotrophs: they are able to fix inorganic carbon through the activity of their symbiotic dinoflagellates and to gain nitrogen from predation on plankton and uptake of dissolved organic and inorganic nutrients. They also live in close association with diverse diazotrophic communities...

Nutrient enrichment can increase the susceptibility of reef corals to bleaching:

Nutrient enrichment can increase the susceptibility of reef corals to bleaching - Nature Climate Change

Increased dissolved inorganic nitrogen (DIN) concentrations in sea water have been linked to a reduction of the temperature threshold at which corals bleach, however, the mechanism underlying this change is not known. This phenomenon is now explained in terms of increased phosphatase activities...

Ultrastructural Biomarkers in Symbiotic Algae Reflect the Availability of Dissolved Inorganic Nutrients and Particulate Food to the Reef Coral Holobiont:

Ultrastructural Biomarkers in Symbiotic Algae Reflect the Availability of Dissolved Inorganic Nutrients and Particulate Food to the Reef Coral Holobiont

Reef building corals associated with symbiotic algae (zooxanthellae) can access environmental nutrients from different sources, most significantly via the uptake of dissolved inorganic nutrients by the algal symbiont and heterotrophic feeding of the coral host. Climate change is expected to...
