Will the refugium flow rate be 300 gallons per hour in the illustrated setup? Also, will the return section be the section which water level lowers with evaporation thus requiring and ato? I think this will work and the refugium flow will somehow correlate with the skimmer net flow (400) and...

I just threw out my three outdated (10 - 15 year old) saltwater aquarium books and decided to get another, as a reference to supplement info available online. Does anyone have any suggestions on a useful book?

Does anyone else have extreme pH ranges dependent on time of day? I am considering dosing my tank at around 11ish (at night) as the pH starts to drop, concluding at around 10ish in the morning as it starts to rise again. I'm worried that the upper value would go above 8.56 though. Does anyone...

I recently purchased a pre-plumbed 90 gallon acrylic tank (with sump/stand) from someone. I noticed that the return line went up through the bottom, back (in the back plumbing housing area). The return pipe goes up near the graded overflow, does a 180 degree turn, goes back down, then goes out...

Not sure what this is growing on the back of my 24g aquapod. I have a pepermint anenome, zenia, kenya tree, polyps, and unfortunately hair algae growing thriving in this tank. Around 6 weeks ago, I noticed a small, soft, "blob" growing on the back and I thought that it was part of an anenome...

I'm taking down my 20 gallon and putting the false perc and small goby into my 110 which has a 4" maroon clown and another false perc. After an hour, the 110 gal perc started shadowing the new perc and doing a fluttering dance next to it. The new perc was/is breathing heavily and trying to...

Although my 5 peppermint shrimp are eating aptasia in my 110 gallon tank, they can't reduce the aptasia numbers which are reproducing at a faster rate. Unsuccessfully using chemicals (lemon juice, Joe's Juice, etc) I then tried to assist by removing a portion of the live rock and power washing...

As a followup to the "if anyone cares about fish. . ." thread that someone posted, I've asked myself if it is moral to keep fish in an aquarium, especially after something died in my tank. I don't know if the life expectancy of aquarium fish exceeds that of fish in the wild, but I don't think...

Does anyone know how to prevent anenomes from getting sucked into filter intakes? Online, I've found the recommendation of using a mesh bag but haven't found a pet store that carries them nor any substitute.

Does anyone know how to prevent anenomes from getting stuck in filter intakes? I looked online and a mesh bag was recommended but have had no luck finding a pet store that carries such things.

Suspects: coral branded shrimp, sally lightfoot, and cream angelfish Background: I haven't seen either of my porcelain crabs in over a week but noticed a couple claws in the corner of the tank, where the coral banded shrimp hangs out. According to the description on SWFs site, these shrimp, as...

Has anyone tried or atleast have more information on the Eco-aqualizer system which is on the ecoaqualizer.com website? I am considering buying this instead of a protein skimmer.

My SW fish/reef aquarium has been running for over 3 months now and everything is in specs. I have crushed coral on the bottom and wondered if the benefits of having sand would offset the process of switching to sand. If so, does anyone know the best way to switch to sand. . or should I just...

Does anyone know the process for adding live rock to an established (cycled) tank? Not fully aware of the benefits of using live rock, I used damsels to establish my tank. I currently have crushed coral and coral (was dry) rocks all of which have algae (and likely bacteria) growth. I'm not...
