  3. Water movement (pumps & wavemakers)
    I am in the middle of planning my closed loop on a 75g and could use some advice. The pump I am looking at is either the Sequence Snapper or Dart. Which would be the better choice for the 75g? Also, how many, what size and where should the holes go for a closed loop in a 75g? Keep in mind my...

    there is an input to the Geoff skimmer near the top of the main tube ... on the inside you could just leave the nozzel pointing in straight or you could install an elbow and point it down or you could have the elbow point left or right and create a tornado in the chamber .... anyone experimented...

    I have had my tank going for about 9 weeks now when I first set it up I used tap water (didn't know better) I now use RO/DI for WC and auto top off. I have a skimmer rated for 150g and I'm really not getting anything out of it at this point. When the tank was new I got a few cups in the first...

    I need some help/advice for SPS. I have noticed that everytime I try and keep a purple colored sps it turns brown slowly. I have tried a purple tort, purple monto cap, and purple digi, and all are more of a purple brown color than the original purple the started out as. My tank perams should...

    all righty folks- working on the build tank and could use some imput. I have only ever had maxi jets and mag pump and even then I know very little about them. I am working on a 29 gallon sea horse tank that needs to be lower flow than most reef tanks. I also need to be very aware of heat...

    I am getting one for my 75 gallon. Does anyone have one? Do you like? Is it hard to install? If so, Kelli will have to come over, drink beer and help me!;)
  14. Substrate Free Tank Husbandry (Bare bottomed)
    I was thinking it might be a good idea to have my overflow dump directly to the skimmer. There is nothing wrong with what is going on now...just wondering if this wouldn't tweak it to being better. The thing is how do I figure out if there is enough to flow through the pump to the skimmer...

    I built a Geoff skimmer awhile ago and it worked perfectly for the first month that it was set up. Yesterday I changed around the return plumbing and now it isn't functioning at all. The water flow is the same as before, but the bubbles flowing through the skimmer are all far too large (1/4"...

    I use a MJ 1200 in my Bak Pak. A few days ago I took it out to scrub and run in FW to clean out gunk. It ran great in the FW rinse. When I put it back on the skimmer, I didn't have it pushed all the way into the intake and it fell out! I don't know how I unplugged it a quickly and safely as I...
