Day 1247: Three years, 5 months

If you follow my youtube channel, you've probably heard how I have to get my arms wet and really cull the 400g reef because the growth at the top is shadowing everything beneath, and those things beneath have little chance of living. I hate to have to rip out these big colonies, but there's no choice. Here are a bunch of pictures of the tank today. I've also included some images of the Anemone Cube. Biggest thing to happen recently was an alkalinity dip. When I see some coral turn white and bleach, I always think it's because of shadowing instead of being a smart guy and testing alkalinity, and yet it again I was wrong and water quality has dropped somewhat. Alkalinity was measuring 7.5 dKH and the big acro at the top took a hit. I was able to correct that mistake, and dosed some buffer to bring it up while adjusting the calcium reactor's melting point a bit lower to increase the total alkalinity of the tank. The effluent coming out of the calcium reactor measures 20 dKH which is perfectly good

Robert LaFlure’s towel.

This week’s topics are Robert LaFlure’s new towel and algae. Robert’s towel is an entertaining story and Christine cooks up an idea that can help spread the word about our hobby.
Algae is a problem for everyone at one time or another. In response to a listener request, we address algae growth in our aquariums and what to do to keep it in check.

Cruise ship crash causes major damage to pristine Indonesian reef

The Caledonian Sky, owned by British company Noble Caledonia Damage accidentally ran aground on a pristine Indonesian coral reef could total well into the millions of dollars in damages, according to environmental groups working in the region. Researchers for Conservation International Indonesia (CII), Papua State University and the Regional Technical Implementing Unit (UPTD) found that the grounding of the 297 foot Caledonian Sky cruise ship on March 4th caused massive damage to several reefs that are unique to Raja Ampat, a remote and idyllic island chain west of Indonesia’s Papua province. “The types of reefs that were damaged by the ship are Genus Porites, Acropora, Pocillopora , Tubastrea, Montipora, Stylopora, Favia and Pavites. It will take decades to restore the reefs,” Ricardo Tapilatu, who headed the research, told

This week is a short follow-up discussion about marine fish breeding. We talk more about Todd, Kathy Leahy’s work and her Reefs Magazine article, and look at all of the captive-bred/raised fish that are now commercially available from Diver’s Den and several wholesale sources. We encourage everyone to buy captive-raised marine fish whenever possible. You’ll save money. Download the podcast here, or subscribe to our podcasts at iTunes.
