even if you use only one pump, consider running two pipes from your pump up to your manifold. Then install two valves in the middle of your manifold (one between where your two pipes join the manifold and the other across the tank from the first valve) which effectively will enable you to have...

My false floor is leaking !! Sorry for the long introduction, but the question (at the end) won't make sense without it. To increase circulation rates, I have converted the "dry" overflow chamber on my DAS tank to a "wet" overflow. My tank is 7 yrs old and its overflow is comprised of two...

Thanks for the pointer Liquid. The link that you specify takes me farther than the other two, but I still get stuck. At this point, all I am trying to do is figure out how to pay for the calcium reactor course. MACO and Brian were kind enough to allow me to register my email rather than thru...

I have made repeated efforts from two different machines to complete my registration for the DYI calc reactor course, but can't get thru the entire registration process. I typically run Netscape on a MAC, and am even willing to try a PC if that is what it takes to log-in. Anyhow, since today...

The sticky note that describes the course lists a variety of sizes of calcium reactors. What size would be appropriate for a system that has 250 total gallons between tank and sump? Since I haven't set up my tank yet, if I build a calcium reactor for 250 gallons, and end up with a smaller...

Shindog asked about installing a short overflow box in the upper 1/4 to 1/3rd of the tank, rather than devoting an entire corner from top to bottom to an overflow. This makes sense, but there is no need to have the outlet of the overflow box come out of the bottom of that box as depicted in his...

Instead of devoting tank space to the durso and its container, why not cut some slots in the back of the tank near the top of the tank and then build an oveflow container onto the back of the tank. This container could be identical to the ones that are built into the corner of the reef ready...

Questions for Nelliereefster: Can the seagrass lagoonal refugium that you describe handle the same flowrate as the sump, or should he split the flow from the sump's pump so that some of the flow goes directly back to the main tank with the rest passing through the sea-grass refugium? How would...

what would be the dimensions of your (realistic) dream tank? I am more interested in its height and width than in its length. Everybody seems to want a longer tank, but I am curious to know people's preferences re depth (front-to-back) and height. Thanks.

I have two 55 gal FW tanks of angelfish because they won't stop breeding! One of the tanks doesn not have an undergravel filter, and the angels in that tank periodically get white growths on the outside of their eyes. I have been told that this is a bacterial infection and have successfully...

My post last week, "How much would you pay for a sustainably caught fish," has yielded many interesting and some surprising responses. After responding to some of those amazing answers, I realized that my response really should have its own thread. So here it is again as a new topic. In the...

In the face of no nets to divers begging for a means to catch fish without cyanide, and wholesalers retailing in L.A., maybe it is time for conscientous hobbyists to align with one wholesaler who aligns directly with AND trains/certifies one or more collection communities. As a hobbyist, I am...

Two identical fish in two identical tanks in one LFS: Fish #1: has a "Green" Certification that confirms proper collection and handling -- nets, no damage to reefs, optimal shipping arrangements, etc. Fish #2: looks identical to Fish #1 but does not have any indication of origin, mode of...

Thanks for all of the responses. I can understand the ease of attaching an acrylic box to back on acrylic tank, but what would you do with a glass tank? Wolfman, I would love to see pictures of your device. Thanks.

Is it possible to purchase a tank that has overflows built onto its back? If not, is it possible to cut slots in the back glass pane of an aquarium and then build an overflow onto the back of the tank by attaching glass or acrylic onto the backside of that pane? Obviously, I am nervous about...
