Hi I've been battling digitate hydroids for a few months now. It started off as a few here and there, and I used to pluck them, or scorch them with boiling water. But after a few months, they've really come back with a fury... The don't seem to sting like I've read, and they also don't seem to...

Jeff: Here's the parameters, I tested just before a 15% water change (weekly change for the last 6 weeks) Nitrate:0.5 (Salifert) Phosphate:0.08 (Hanna) Ca: 400 (Red Sea) Alk: 7.6 (Red Sea) Mg: 1320 (Red Sea) Salinity: 1.023 (Red Sea) PH: 8.34 (Apex) Ingy: Interesting. I looked around for a...

might be too late since the tank is setup, but you can try painting the back of the tank (or at least get some blue or black aquarium background wallpaper). I should add come color and draw attention away from the 'wall of white' you got there.

I've been thinking about a DSB also, but since my nutrient levels are so low, do you think it would make a difference? Also about the live rock, or rubble. What benefit would that have? I have about 45lbs of dry BRS rock, not sure what the is in terms of wet rock. I thought that would be...

Hi All I've had a 10g sump under my 36G bowfront for over a year now and I haven't been able to really make use of it. In the first chamber, I have a filter sock and a skimmer. In the last chamber, I have the return pump and a MJ1200 pump for a GFO reactor. The middle chamber is my problem...

I thought about the skimmer too, but I only dump out a 1/2 cup every few days.

I'm using the same instrument to test the mixed incoming water and the current tank water. If the baseline calibration is off, it'll be off for both. What I'm seeing is a relative difference between the two, which indicates it's not a simple calibration issue. That said, I'll check and...

Thanks for all the responses. I'm not using an air stone nor do I have excessive salt creep. I am using a refractometer for both the mixed saltwater and the tank water, so they're both calibrated to the same source. The tank is on hardwood so it should be pretty evident if there was a continuous...

Hi I've had a strange trend occurring the past few months, tipped off by my corals lack of growth and eventual shrinkage. My tank's salinity levels are dropping and I don't know where it's happening. So, rewind a few months back. My tank's already been setup, but I add my first coral, a Pom...

Looks like I have the same tank you have. I have a 4in yellow watchman goby. Gets along great with my pistol shrimp. What kind of plumbing do you have?

That's good to know... I was going to take all the rocks out and scrub and rinse it. Was also starting to look at buying a bunch of chemicals and possible a shrimp. So they just pop up during the first year and slowly go away?

Never really noticed it till the wife pointed it out. After that I realized it was on all my rocks and on the glass too. Not sure what they are... Just a brief description... they're really small (less than a 1/4 inch, most were about 1/8 inch) and white. It has circular opening, with what...

I have an Neptune Apex Controller with 8 outlets. When I first started, I thought that this was going to be more than enough (I only used 3 for my freshwater setup). It didn't take long for me to realize that I was going to need a lot more outlets. Now I'm wondering if I need to get another 4...

I didn't think the Taotronics had a timer option... the only ones I saw with with dimmer and without. I think the with dimmers was an extra 50 dollars.... I just bought the dimmer last month, if I knew there was one with a timer option, I would've definitely bought it...

I set them as low as possible, which is still pretty bright... I do wonder if I should get night lights of some sort... it does get really dark at night... it'd be nice to somehow simulate the moon.

Hi all. I have a set of 120 watt lights. Currently, I have them on from 3pm to midnight. My rationale being that in the morning and afternoon it would be fine with natural light. I just got a pom pom xenia. A few nights ago my son woke me up at 4am and I noticed that the xenia was closed up...

here's an updated picture

Hey faye Thanks for the help. it's the best picture that I have... I'll try to blow it up. But from what I remember, you could see most everything, the little pinchers, a few legs, and in the back it looks like tissue. I originally thought my pistol shrimp tore it out of it's shell to eat it...

I've had this happen every now and then. Just noticed another casualty today. Is this my hermit crab? Why is this happening?

Thanks for the info... For the cyanobacteria patch, it seems like either lighting or nutrients are the main cause. I have an ordinary T12 full spectrum bulb right now and that's only on between 6pm to midnight. I don't have anything powerful, yet. I was going to wait a couple more months before...

Hi All, I have noticed over the past weeks a couple of strange growths. The first picture is of a big purple spot, about 2x2 inch across. At first I thought it was the coloration returning to the fiji rock, but after wafting the rock to clean it, I noticed it tear near the top. The second...

Jmkb02 Would sand or mud get sucked up into the return pump? Can would the detrius really be cleaned up be the snails or would they just be hidden in the sand? As for the sump, I originally had a piece of glass where the eggcrate was, but my original pump (Mag5) and my second pump (Sicce...

That's a lot of poop... i thought the skimmer was supposed to take that out.

Sorry about the crappy picture... here's a better one

Hi all I've had my aquarium setup for about 1/2 a year now. The refugium is about the same age. I started noticing this brown gunk a few about 3 months into it and I'm not sure what it is. It's getting worse as time goes on. Anyone know what it is and how to deal with it? I currently have the...
