Folks, if you've recently upgraded or renewed your annual club membership but it's still not active, please reach out to the BOD or a moderator. The PayPal system has a slight bug which it doesn't allow it to activate the account on it's own.
I would not use the presence of Asterina as a indication of water quality. It certainly is a good sign that they are alive, but you really can't take the place of doing the proper testing for water quality using your test kits.
Sounds like you have Asterina starfish. There is a love/hate feeling about Asterina. Some folks don't have a problem with them....others want them out. Note that a very small percentage are known to eat certain corals. The general belief is that white is safe....colored Asterina could...
Wait one minute......wasn't this a tank with sharks, rays and lionfish???? Guess what.......trichlorfon should not be used on these guys. So death would have happened anyway. Something smells fishy here.
Here's the warning right from drug information:
DO NOT USE ON FISH THAT ARE...
The smaller (male) isn't ignoring the anemone. It's the mean, overbearing, dominant female that's hogging the anemone saying, "This is mine! Keep out!!!" My male us to try and sneak a feel from the anemone by swimming and staying underneath the anemone.
Go Glass-Holes overflow. You need to drill the side glass.....and the kit comes with the drill bit. Here's the 1500 gph overflow with two 1 1/2 inch drains. The 700 kit only has one 1 1/2 inch drain.
Welcome Nikki. You've found a great site. I'd suggest starting a Tale of the Tank where you can post info on your tank and ask away with questions you might have.
You also may wish to consider a refractometer over a swing-arm hydrometer. Swing-arms tend to be accurately inaccurate. What I mean by this is that a swing-arm will consistantly give you the wrong number. Because of this, as a minimum, consider calibrating the swing-arm to someone who...
Yes! You get three fixtures. Search ebay and you'll find quite a few that are very similar....around 87 - 90 each....with free shipping. And I know nothing specific about these fixtures......but I'd give them a shot at that price.
Your budget and whether or not you want full controllability will help determine the fixture(s) best for you. If you want least expensive, full spectrum, two channel, manual control......you can't beat THIS deal.
Now you could most likely get away with just two of these fixture, but I'd go...
Here's the trick about bottle traps.....you cut a small hole in the side to fit the end of a turkey baster. Put the trap in your tank....actually leave the trap in your tank so the fish become use to it. Now fill the turkey baster with some delicious food.....I use mysis. Put the turkey...
Well HERE is the extension Y cables I was talking about:
You can also get similar three or four versions of these....
But if I'm not mistaken, I thought you had six fixtures. You might just want to use two power strips and tie all the blues togother and all the whites together.
Karen, you can also combine thhose cords using "Y" or even triple or quad short extensions. I'm not home right now, but when I get there, I'll post what I'm talking about.
I wanted to reply to a post I saw on The Reefer's Lounge and to do so I had to sign up.....and be approved. I was supposed to first post as a guest in POST HERE, but there was no way to do this. The last POST HERE was from 2013. So I submitted my info anyway, about three weeks ago, and...
I would definitely buy a new sediment filter and carbon blocks (and DI). I'm not directly familiar with this unit, but if it doesn't have TDS capability, I'd pick up a TDS tester and use it to check the membrane. Most good membranes for 75 gpd have a rejection rate of about 98 percent...
Do you see small little tubes....about 1/16 inch diatmeter? If so, these are vermetid snails....that can't move like a conventional snail. They put out sweeper tenticles that look web-like. Do a search on vermetid snails and look at the images. That's my guess.
