I've had 3 pigmy angels together in a 55g reef with no problems at all- a Coral Beauty, Flame Angel, and a Bi-Color Angel. They were all introduced...
In my own personal experience (and a few others here), they have attacked LPS corals and some anemones. OTOH, I've read from several places that...
For the most part, corals prefer that the lighting not be changed unless they're unhappy with what they already have. IOW, if your corals are opening...
Not knowing the history of the tank, the sand may be loaded with detritus and nutrients that can pollute the tank when disturbed. I have moved and...
Did you not appreciate the answer you received in this thread? FWIW, Matt tends to give excellent advice. He also asked questions that you failed to...
+1 to Pineapple Sponge. FWIW, there are many species of sponge that seem to crawl out of the sand or rockwork. All are equally harmless and...
It was the opposite for me, but I guess it depends on who's in the tank first. If you want multiples, cleaners are the way to go. The CBS are loners...
I've had featherdusters for years and have never target-fed any of them. They are filter-feeders and will get plenty of nourishment if you are...
Hi, and Welcome to 3Reef! I've seen several members post about MarcoRocks.com claiming them to be the best that they've ordered from.
It depends so much on your individual system that it's impossible to define what's right for you. I.E., for smaller tanks (40g or less), I prefer 10%...
+1 to all the above. Also, underwater creatures can, in fact, sense barometric pressure and many other atmospheric conditions, even in a glass box...
Exactly. Most die-cast metal models are made of cheap alloys. God only knows what's dissolving into the water...
Had a friend who purchased an existing, 6-yr-old reef tank a few months ago- he got it moved and set back up the same day. That one did have a sump....
If you need to upgrade your existing light fixture, you'll save in the long run with T5. PC is old technology, and there are reasons why it's being...
Looking great, Steve!
Yes they can be mounted in a canopy, but I'm curious why you would DIY a PC unit. For any application, T5 bulbs are cheaper, last longer, produce...
+2 You NEED to feed enough to keep everything healthy, whether it 2, 3 or 5 times per day and take the other aforementioned measures to combat cyano....
+1... A fuge with macroalgae is always a benefit to any system. You may want to use an oversize skimmer though, maybe one rated for 200 - 225g to...
First, let's determine exactly what you're using: Your 20L is 30". A 30" T8 fixture uses 24" 17 - 20W bulbs; 30" T5s are 31 - 35W; 32W T8s are 48"....
ROFL! That's funny. Nice video too, BTW. :)
