    Alright everyone who has or hasn't been following me. As some of you may know I've had some struggles over the past 8 months with my tank. At one point almost shut it down. But I'm glad I didn't. Anyways I'll get to the point. About a month ago I remember looking into my overflow because I was...

    So it looks like I now have white sponges growing in a few places in my rock. My rock is the fake LR type that is made in California and impregnated with red dye that contains bacteria. It eventually becomes like LR but without hitchikers. I am wondering how my sponges came. I don't think...

    OK, I need for someone to tell me exactly what these are. They are purple in color and are currently 4-5 inchs tall. They started growing out of my live rock about 9 months ago. At first I figured that they were some type of algae, so I would clean them off. After a few times I decided to just...

    Hello, I'm moving tomorrow and I have a 45-50 gallon reef tank. I have a two inch sand bed. The tank is two years old, should I change my sand? Can I use 50 % of my water in my tank to keep for the new house? Should I keep more water than that? I don't want to spark a cycle. I planned on doing a...

    Does anyone know what water requirements are needed for generally good health ? Ultra clean water or higher nutrient water ? What type of lighting exposure ? What should I look out for when buying them ?

    Hi there! My tank is looking healthier and I have had a lot of recent growth. The reef is two years old. It's a 50 gallon. It has a skimmer, rodi unit, I use instant ocean I think for salt. I got a new t5 daylight bulb, 12,000k. Looks good just thought I would share:)

    I started a 16g saltwater tank 3 weeks ago. I added a live rock 2 weeks ago and I'm finding all sorts of fun stuff on it...most of which I don't know what it is. A few things I have been able to identify (I think): halimeda, coaralline algae (hithohamnion and hildedronia?). I thought most of the...

  9. SPS Coral Forum
    Hello everyone I run my reef for about 2.5 years now. There is about four months since I introduce my last coral (an acro digitata). The rock I got was a dry rock that is seeded with coraline over time, however I experience a some sort of Sponge invasion recently. I have no idea where they come...

    As you can see, I have a nice group of sponges on this one piece of LR - they are ONLY on this rock. They've really been taking off and I'm wondering if I should remove them or leave them be? Is there any reason not to remove them while still in the tank? Thanks! angie
  11. General Reef Discussion
    Hey guys, Just wondering what everyone's thoughts were on pineapple sponges. Who takes them out immediately and who leaves them in and lets them work? I know the sprout up because of high silicates, but in my opinion, they're performing a service and aren't really a "pest". I use RO/DI water...
  12. Pests, Hitchhikers, and Diseases
    I need help figuring out what these are - I got a small chunk of LR and these were attached. These are the best photos I could get as they are small. Any ideas? The black one actually looks almost like a brillo pad (if that makes sense) THanks! angie

    These things are growing like wild fire, all over my back glass, and all over if I dont keep the glass scrubbed. Along with these nice looking white feather dusters, NO clue where those came from. Just got some new LED lights, that are pretty low now to acclimate some of the corals i have...
  14. Pests, Hitchhikers, and Diseases
    I have what I believe to be a sponge infestation that I can't eradicate! I am posting a pic so maybe someone can tell me exactly what this is and what to do about it!
  15. Non Coral Dominated Systems
    Does anyone know anything about sponges in a reef tank? im looking to buy a Australian White lightning sponge, but i cant find much information about them. i know that sponges can be iffy and can kill the whole tank if they are stressed or die, and they can do the same thing on the way into the...

    I have a green sponge it was all bright green at first and now it's slowly going black underneath.. Don't understand why it's changing colour is if dying ?
  18. General Reef Discussion
    Does any one have real sponges like the ones from liveaquaria? If so are they easy to take care of (after a good acculamtion (sp))? I really like they way they look and add color to the tank.
  19. Pests, Hitchhikers, and Diseases
    I think there sponges? What is the best method to remove them? What eats them? and why do they grow? Thanks for the reply. Tanks been up for 6 mo. Levels up and down. Once a week 10% water change. Fish and reef mix. UV, LEDs lights.

    Hey those little white things in my sump overflow I finally figured out were called pineapple sponges. Are they all right to keep in there? They sure did repopulate quickly.
