    Water movement without closed loop

    It is a 75G tank, 48x18x20, with a 40g sump. I have yet to decide what pump I will use as return, but one limitation is that there will be a 3/4" sea swirl on the return, and it's maximum flow is 850gph. This will likely be place in the back left corner, near the overflow. I have committed to...

    Water movement without closed loop

    Thanks Don. I have a deal on a 6080 I am thinking about, and may just go with that for now. I may consider upgrading to the Vortech or controllable Tunze's in the future.

    Water movement without closed loop

    Is it possible to get back on track? :) I appreciate the discussion, but it doesn't help me make a decision. I am too lazy to mod a MJ. I am likely going to purchase a Tunze 6080 unless someone tells me that another (non-mod) setup up would be better. I like the fact that I can swivel the Tunze...

    Water movement without closed loop

    75 gallons. Sorry, should have said that in the first place.

    Return pump flow rate

    I will soon be setting up a 75g tank with 40g sump. Is there a limit on how much flow should be run through it. I seem to recall reading somewhere that flow through the sump and the flow rate of the skimmer should be close to the same, is this true?

    Water movement without closed loop

    I am in the process starting a new tank. For a number of reasons I do not want to create a closed loop system. So that leaves me with needing to create flow. I want to put some SPS in my tank, but will also have LPS and softies, along with a few fish. I am very intrigued with the Vortech pumps...

    What company is right for me???

    Where do you live? Brian at Innovative Aquarium over here in Kitsap County (WA) makes great tanks.

    No skimmer system

    I think this is a great idea, and exactly what I plan to do when I get my large tank. It is also what slickdonkey is doing on his new 240g. The sump design I plan on using (and slickdonkey has already built) will be a knock off of the model F sump/refugium from Melev's Reef, built to fit my...

    Help me design my new 240gal setup!

    I think you chose well with the model F design. When I get my new tank up and running I am going with the same model. I like that design exactly for the reasons you mention; it allows for a higher flow through the skimmer section, while you keep the refugium area with lower flow.

    Kent Salt Mix Has Low alk

    I'll bet is was your alk and not the temp. My nano tank varies during the day from 79-81.5 and so far (knock-on wood) things are going great. However, I recently almost lost my favorite coral, an alveopora, when I let the alk get >20. After all the reading I have done since, I am convinced that...

    My Aquarium Pics

    A big thanks has to go out to Eric at the Shark's Reef. I have obviously been remiss in thanking him publicly. :lol: My tank wouldn't look so great if it wasn't for Eric and Will and all the time they have spent answering my questions. I have asked 20 times more noob questions at the Shark...

    My Aquarium Pics

    Still a very young tank. It was set up in early February. I target feed it twice a week with frozen mysis, at "dusk" (just after the daylight bulbs turn off). That picture is from last night, about 30 minutes after feeding. The rest of the tank gets liquidlife bioplankton and coralplankton...

    derasa clam

    Great Pics April. I think I'll have my new tank up and running before yours is swapped out. :D

    My Aquarium Pics

    And here are my larger corals. The first is my daisy coral (alveopora sp.), then my hammer, and finally my sunflower. As an aside I added the sunflower to the coral gallery, but since there was no specific category for the tubastrea species, I added it to the turbinaria category. It was the...

    My Aquarium Pics

    After asking lots of noob questions, and a recent scare that I was killing my favorite coral (thanks to a dKH of >20, see this thread) I have decided to post some pictures of my tank and a few of the inhabitants. They show the progression of my tank, from first adding water with a few LR...

    Sun Polyp - Tubastrea sp.

    Like the Turbinaria spp., they "sun" or "sunflower" polyps are asymbiotic; that is, they do not possess zooxanthellae. The polyps are large and extend mostly at night, although well fed and/or trained polyps may emerge during the day as well, especially if food is present. These

    coral ID help

    Well, I think I am on the right track finally. Polyps stayed open all day. Alkalinity has stayed constant at 16.6. I dropped a venturi airline onto a powerhead to blow some bubbles into the tank and the pH tonight is 8.0. Calcium is steady, dropped to 340 on tonights test. Will change water...

    coral ID help

    Yesterday, before any water changes it was 360. Did not recheck today. I figure that my salt mix (Instant Ocean) generally has a Ca level in the 300's so I am not worried about the Ca right now. I never have understood the whole pH, Ca, dKH "balance". If you have a good link that explains it, I...

    coral ID help

    Thanks for the words of encouragement. dKH this morning is steady at 16.6. Polyps are all visible, and appear to be opening. Will retest tonight and do another water change and feed the tank.

    Power compact sockets

    C'mon Dan, Ad hominem arguments really aren't needed. Criticize constructively, but not this way. Liveforphysics methods are unconventional, and if he did this in a tank with livestock, too risky for my taste. I would hope that he tested the waterproofing of his silicone in the sink or tub...
