Enough to make an overflow box that is 10"x6"x6" i'll take what I can get.

Reef crystals is considered a "higher end" mix by many aquarists, and ranked well in the borneman study. Borate alkalinity is not bad. It can become a problem in aquariums that benefit from a calcium reactor. This is why people use tropic marin pro. Aging saltwater is a topic of debate. If many brands are mixed at too high in salinity and with improper aeration, they can precipitate various cations (alkaline earth metals) including but not limited to ca, mg, barium, strontium etc. Here is some info on whether to use tropic marin pro or not. To decide which of the Tropic Marin sea salts are appropriate for your tank please use the chart below to compare the specifics of your tank and count the plus for every sea salt. Pro there is a wide variety of organisms; your tank is a mixed community tank. there is a slight additional demand for calcium and carbonates, which is satisfied by modest additions of calcium through supplements or by a calcium reactor. the number of hard corals is quite high: you have a reef tank with a high demand for calcium and magnesium. buffering and calcium supply is done by high quantities of supplements or by a calcium reactor with high flow rate. the alkalinity tends to increase to more than 9?dKH. To use regular Tropic Marin the alkalinity (KH) tends to drop below 6?dKH. the number of calcareous animals is rather low, so the calcium level does not vary strongly even without additional calcium sources. there is a wide variety of organisms; your tank is a mixed community tank.

Glad there is so much interest. Here are a couple of pictures of the type of joints that I make. But don't worry, I don't test all of my sumps/tanks in this way.

John, you forgot to mention the unlimited free beer and dozens of hot chicks running around the store "fetching snails from the colder tanks" like in duece bigalow. Only in a perfect world...

Does any one have any black acrylic, I am working on a project and Regal is closed for the weekend. i can give you cash or some kick *** frags.

A. echinata have the ability to have fused coralites at the fringes of the coral polyps where A. lord coralites do not fuse, but spread as individual polyps. Their flesh makes both appear similar similar, but echinata is more colonial.

If your fittings are still leaking, replace j.a.c.o fittings with John Guest fittings from lowes.

Since so many people got green slimer frags of roughly the same size lets hold a contest. If you got a frag, bring a picture to the next meeting and we will compare color and growth. The person with the best picture will be crowned reef master of the universe!

I'll talk to andrew about it. I wonder if it would be better to hold the auction at meeting, or a few days b4 somehow. This would give a little more time for planning. We will start to hash out details.

I was thinking that at the next meeting, we could start it by having a raffle (selling tickets to raise money) then building a sump for the winner in conjuction with a DIY acrylic class that I could teach. We will donate the materials. Thoughts?

Great meeting. What a cool tank, with great color and rockwork. I certainly hope we can have one in 4 weeks or so. I am trying to talk my friend into hosting it so we can check out his 600g sps tank.

I guess my previous post will only make sense to those that have have tried to do acrylic work before. Any interest in an acrylic workshop at the next meeting??? i saw a cool underwater camera box at macna made by melev that I can dudlicate.

Great posts, so I think that the consensus is that the coralvue Reeflux 12,000K bulbs without actinics, (or with if you like it extra blue) is what most people are using these days.

Macna tip: When building tanks/sumps with acrylic using weld on #4, glue joints indoors with the A/C set to 70 degrees for 4 hours to cool down the glue and materials. Then using 15/1000's piano wire to add a little space to the glue joint, add the weld on #4 with a syringe through capilary action. Then after the glue is in the joint, remove the piano wire from one end to another for a bubble free glue joint. When using the two part weld on #40, cut the material at a 5 degree angle and inject the WO #40 into the joint using the piano wire method. Then , once dry, route off dried glue with a laminate trimming bit.

I like the current dual daylight alot, but i have found that their dual actinic (which is a good bulb) is not enough to balance out the dual daylight enough to give you that crisp "12000K ish" look that everyone is looking for. i would suggest that you buy an all true actinic that peaks at 460nm. Yall will have to bear with me on the technical posts, its just that at macna everybody talked like a reef geek and it just rubbed off on me.

I have installed a few super skimmers of each size, and I have noticed that the work well as long as the water level is kept as constant as possible. And I agree with Gabe, the 220 is worth the little extra.

Word!

Hair algae growth can often reduce nitrates, but are usually sparked by elevated nitrates, go figure?

I said this before, but i'll say it in a more controversial way; Borneman's salt study sucks, and is not that applicable to a reef. The study should be called: How various salt mixes effect small tanks with virtually no live rock. Live rock introduces so many chemical and biological factors that are not taken into consideration in this study. The biggest flaw that i see in this experiment is that the test aquariums are two 48" 55g tanks divided into 4 cubes with 48" light bulbs over the top. Fluorescent bulbs are much more intense in the center than at the ends. So, the cubes in the center recieve more light and may have shown higher algae growth rates. Plus, it is irresponsible for any scientist to post inconclusive results from a study that isn't even finished. (I am still switching to tropic marin though) Gosh i'm such a hippocrit.

I just picked up a few Coralvue reeflux mogul based metal halide bulbs that I absolutely love. The color is great and it is quite bright. Anybody else out there using these? If not, what does everyone like?

This type of algae is very common. It is a simple single celled green alga or dinoflagellate. This may or may not be the case, but it is common in aquariums where fluorescent (or esp. PC) bulbs age and begin to emit more of a yellow to red spectrum than the blue/violet spectrum. If your white bulbs are over 10months or actinics/blue over 8 months I would suggest you change them. ' Check phosphate and run some carbon. These simple algaes can often bind to activated carbon. (Good carbon that is, like hydrocarbon2 by two little fishes)

My bad the CS8-2 is now called the CS165, and it still sucks!

Euro reef may be a great alternative for some/most people. There are some issues with some of their products. First and for most customer service is not very good at all. The company has grown very quickly over the last 2 years, and they have become very busy. It can often take 2 weeks to get a response and thats for vendors! Try calling as a hobbiest. The CS6-2+ (now CS135) is awesome I love it so much sometimes I often talk to it and tell it how beautifull it is and how much I adore it. But the CS8-2 (CS135) is the most overpriced piece of junk on the market. As is their 12" diameter skimmers over 2' tall. Euro-reef was not an option for most aquarists 4 years ago when they all ran on expensive eheim pumps. After switching to sen, sedra, then finally dolphin pumps, people could finally afford these skimmers. All of these skimmers are now discontinued!!! You may be able to get one for a few more months, but then the new model kicks in. All new Euro reefs will be recirc. skimmers with EHEIM pumps, which is great for performance, but I think that we will all see a drastic increase in price. Sorry, i am starting to rant, i'll shut up now.

Q1: I am just regurgitating things that I heard at macna, again. But what Bruce at rowa recommends is that you do not constantly remove and add phosphate absorbing resins. You regulate the phosphate in your tank by adding a small valve to your 2 little fishes or kent reactor. You adjust the flow while testing both the tank water and the water coming out of the reactor (the effluent), much like you would a calcium reactor. Q2: And yes, I worked at Aquatek for about 6 years during college. (and yes I went to college for 6 years) Q3: The tank that I am finishing up on is about 600 gallons, it is a custom made acrylic tank that is 96"x48"x30"tall. It is home to mostly stonies, clams, and lps. Due to time and budget constraints, the tank and support stand have been set up for some time, but I am just now getting to finish building the cabinet and canopy. I will post a ton of pics in 2 weeks when it is done.

Coralvue's new HOB looked good yet cheap at macna http://www.coralvue.com/hob.html
