EcoTech Marine MP60 Propeller Pump

 

© Dana Riddle & Advanced Aquarist Magazine

 

This review will report on operational issues of a MP60 that has seen over a year of service. How well did the pump hold up? What problems, if any, encountered? These questions and others will be answered below.

 

This article will conclude the product review series of EcoTech Marine's propeller pumps, and our focus this time will be upon the largest of their currently available pump and controller, the MP60.

 

We'll examine this pump's performance in different operational modes as well as power consumption.

Maxi-Jet Pro Series Pumps

 

© Dana Riddle and Advanced Aquarist Magazine

 

Marineland Aquarium Products' Maxi-Jet pumps have been around for quite some time. Recently, their design changed as well as their country of manufacture. The manufacturer promises relatively high performance while offering them at very modest prices. Is this a case of 'you get what you pay for' or are they a true value?

 

The art and science of reefkeeping continues its steady progression with introductions of equipment that we only dreamed about in the hobby's early days.

 

Early on, it was recognized that lighting was critical while water motion received relatively little attention.

 

Since the reef hobby was such a tiny fraction of the aquarium trade, few manufacturers were catering to the needs of reefers so hobbyists were forced to improvise.

 

Serious hobbyists were handcrafting dump buckets and siphon-based Carlson Surge Devices. One dedicated aquarist, Jimmy Chen, modified a Little Giant™ pump by adding a model boat propeller.

 

This ingenious concept would have far-reaching ramifications and eventually revolutionized the way we move water in reef aquaria.

Mystery of the White Reef Slime: Part III

 

© Coral Magazine and Lance Ichinotsubo

 

Links to Part I and II are available in the article

 

Thanks patback for finding it and posting it

 

This third segment brings to a conclusion almost three months of work, research, treatment and finding cure for what I think of as the “mysterious white reef slime effect.”

 

This White Slime is found in our tanks and the article explains why: you may be surprised when you read the reasons!

If a short etiology would help, this thing that looks microscopic was actually visible, the size of a common flatworm

 

But it was pelagic, floating around in the current and not on substrate like the flats

 

It would actively swim to different areas in the bowl, rest on a rock, then flutter around exactly like a jellyfish

 

My best guess is a brooded planula from either xenia or my alveopora

 

After I put it back in the bowl I never saw it again!

 

Brandon, that looks and sounds exactly like the ephyra of a jellyfish. I would bet $100 on it. They strobilate from a polyp that could have easily hitchhiked in on a coral or rock.

 

 

Very Unusual: Looks like the Ritteri IS Floating ...

Looks like the H. magnifica is trying to get as close to the light as possible. ;) The Trachyphyllia at the bottom of the tank looks pale from not enough light. I imagine that will not end well for the anemone. :angry:

 

Black Snail or Whatever it is ... is Not to be Found this Morning

If anyone has any suggestions on the ID do let me know please. Tks.

Wombat :

 

Thanks for the ID's for Brandon's specimen and also for the Black snail that I suddenly discovered, and yes looking at the link you gave I can find a black strain when I scroll down, although usually what I have seen are the tan colored varieties, but then in nature things do sometimes if not often surprise us.

 

As you said elsewhere, I too wonder what the color adaptation really means for it ... survival? Geographic origin? Who knows ...

 

Agreed on your comments on that big tank ... most of what is on the bottom does not look all that good indeed.

 

Again thanks for your input and the ID's

Stomatella varia ... the Black Snail/Slug in my Tank

 

Wombat ID'ed the Snail as a Stomatella varia but of the Black Color variety ...

 

Below is a picture of one posted and © LynnZ on http://wetwebmediaforum.com

 

Here is some of what LynnZ has to say about them (material is © LynnZ)

 

Color

Varies from mottled shades of green, tan, brown, cream, rust, gray, pink, even blue, to solid black. The shell itself can be mostly smooth or appear a bit rough due to some short, raised, almost papery areas sticking up from the surface.

 

Size

The shell maxes out at about 1.25” for the larger species.

 

Note

The species name most often attributed to these common hitchhikers is Stomatella varia, but there are at least two other possibilities that may be misidentified on occasion.

 

Those two species are Stomatella impertusa and Stomatella planulata. The problem is that they’re all very similar looking, their range overlaps, and complicating things is the fact that they do vary so much within each specie.

 

The species name “varia” in Stomatella varia is indeed a most apt description. Please see the links listed at the bottom for photos and more information on each specie.

 

Diet

Stomatellids are herbivorous grazers that eat microalgae – including diatoms and dinoflagellates, as well as possibly cyanobacteria. They do not eat hair algae.

 

Compatibility issues

Fishes and the usual “pickers” such as shrimps (especially Peppermint shrimps/Lysmata wurdemanni), and crabs will eat these little guys. The Stomatellids themselves are peaceful and pose no risk to corals or other livestock. They'll do fine in systems nano-size and up.

Of course ever since I saw it last night, I have not seen it again however hard I looked :-)

Matt and Albert thank you for lending some support to this id quest! Now that you mention it Matt I think I remember you saying that a few years ago when I was looking around for it, hard to remember thousands of posts ago lol

 

I was fascinated by what looks like zooxanthellae packets in it, perhaps an early nutrition booster as the larvae prepares to settle and transform

 

Makes me possibly regret removing it for id with a McDonalds straw siphon lol, too much stress for it along with dorsal ventral compression from being put under a cover slip lol

 

Really a nice collection of work Albert, id also never seen the black snail as well.

Indeed Brandon it is amazing what one finds in one's aquarium sometimes and how difficult it can be at times to actually identify what it is ... but here we got two ID's ... so thanks again Wombat.

 

Yes pity maybe that you did remove it ... who knows how it would have turned out in the end.

Skimmate from my Red Sea Prism Pro

 

 

Guess that based on the color, the skimmer is working well and that the water did contain quite a bit of matter that needed to be removed after I blew and squirted water on, behind and inbtween the rocks yesterday.

 

What you see is just a portion of the liquid it took out but the color is what I wanted to show.

The Diversity and Biogeography of Western Indian Ocean Reef-Building Corals

 

A Research Article by © David Obura and plosive.org

 

This study assesses the biogeographic classification of the Western Indian Ocean (WIO) on the basis of the species diversity and distribution of reef-building corals.

 

Twenty one locations were sampled between 2002 and 2011. Presence/absence of scleractinian corals was noted on SCUBA, with the aid of underwater digital photographs and reference publications for species identification.

Hey Brandon, if it really was a jellyfish ephyra then it would never settle down again and just continue growing into a jelly medusa. At that size you would have needed to do twice daily feedings of rotifers for a while to rear it successfully.

 

That does indeed look like zooxanthellae inside. Lots of tropical jellies are zooxanthellate--Casseiopeia, Catostylus, Rhizophyllia, Mastigias, etc.

More on Stomatella Snails and Pictures

 

Since we saw pictures of Stomatella varia, and since their are other species, here are a few pictures of those snails which by the way as pointed out in a previous post are not always "black".

 

- S. planulata

- S. impertusa

- and a few more of S. varia

There Are Many Myths In Our Hobby and No One Really Knows Where They Originate

 

Some get posted on a Forum and read by a few, who then go on and post them on other Forums, and so on and sooner rather than later, the Myth is to be found everywhere and, unless one is or has been in the Hobby for a long time, many readers of those posts will believe them and repeat them.

I came accross 3 Articles by Eric Borneman that demystify the many Myths that are going around in some Hobbyists circles. Here are the Links to them.

Aquarium Chemistry: Regeneration of Granular Ferric Oxide Media

 

with Sodium Hydroxide

 

Copyright: Matt Wandell, Laura Kormos and Advanced Aquarist Magazine and Blog

 

For aquarists who keep non-photosynthetic corals that require massive feeding, have large tanks, or a dense fish population the costs of regular GFO replacement can be significant.

 

With a few simple tools and techniques we can easily regenerate GFO so that it can be reused several times over.

Eric is particularly infamous for writing this line:

"Myth 5: The "K" rating of aquarium lamps plays an important role in the coloration of corals."

 

NOT a myth!

Agreed Wombat ... and as it drops in spectrum level it creates other issues too, e.g. outbreaks of undesirable growths in tanks as quite a few have experienced when they do not replace certain types of bulbs soon enough.

 

But ... I just posted the links to the articles, and as I have always maintained ... hobbyists should read up on any information they find, and check various reliable sources and then make up their mind.

 

Some of the other ones he brings up are IMO not totally myths either ....

 

Thanks though for pointing it out .... I appreciate it.

Venomous Velvetfish: Caracanthus spp.

 

© Felicia McCaulley and ReefTools.com

 

Some of my all-time favorite fish are fish in the genus Caracanthus. There are four species in this genus, though only two are common in the pet trade — Caracanthus maculatus from the Indo Pacific and Caracanthus madagascariensis from Africa.

 

Some common names for these fish are Velvetfish, Velvet Goby, or Gumdrop Coral Croucher. Velvetfish are often called gobies, but they actually belong to the order Scorpaeniformes like scorpionfish and anglers.

 

The specimens from Africa are the most colorful, having pink bodies and red spots to resemble the Pocilloporid corals they inhabit.

Aquarium Chemistry: Calcite, Aragonite, Limestone, and More

 

© James W. Fatherree and Advanced Aquarist Magazine ( 10/2011 )

 

It's been said a million times that aragonite helps buffer aquarium water, or helps maintain calcium concentrations, while other (carbonate) substrates do not.

 

However, to the best of my knowledge this simply isn't true.

 

Essentially everything solid in our aquariums that isn't made of tissue is made of calcium carbonate, so it's worthwhile to know a bit about it.
