Yes, a pic would help. It might be coralline algae, but it could be encrusting sponge. Won't know for sure until we can see it.
+1 Definitely go with the Hanna.
Excellent video, link248... K+ :) Yes victor.m, your overflow is supposed to never lose it's siphon. Is it possible that you have the U-tube on the...
FWIW, I've seen larger reef tanks (40g+) that have been running for 6 years+ without a skimmer, so regardless of the reason, it most certainly can be...
Looking good. :) Lots of nice frags in there. They all seem to like your LEDs, too.
Yes, this is true. However, most can thrive in a range of light levels, and they can also be acclimated to higher lighting if done properly. :)
I'd be concerned with the possible effect of suddenly removing that much of your bio-filter. Vacuuming the sand bed periodically will keep it...
Possibly vermatid snail feeder threads. Can you get a pic?
Welcome back to the hobby. :) Personally, I would remove the bio-balls permanently. Your live rock does the same job only better. Also, if bio-balls...
Hi, and welcome to 3Reef! For a FOWLR tank, any light will work. If you think you might want to add corals in the future, I would recommend the...
I also have a glass cover for the very same reason, but others hang their fixture high enough to prevent spray/splatter from reaching the light.
The rating only specifies the maximum flow. Only proper plumbing can prevent floods, not the pump size or actual return flow rate (as long as you...
I usually just use a sharp knife. A file would also work.
First, you will want to use PVC cleaner/primer on the inside of the fitting and the outside of the pipe at each connection. This will soften the...
That does look pretty extreme, although it would depend on how much was in the tap water to begin with. For the sake of knowledge, I would suggest...
Kudos to you for having the heart to save them. I don't agree with flushing a live animal just because one decides they don't like it anymore, even...
Hmmm, if you don't know any reefers in your area, you may be stuck with buying a small bag of live sand. FWIW, if you have a shallow sand bed, you...
If you have detectable ammonia in the 10g, then the tank is still cycling. You most definitely should wait before putting anything in there. Both...
Oh, now that just makes me jealous!! <jk> ;) Good luck! :thumb_up:
There are several species of asterina. AFAIK, it's the only one you will find with four legs because of how they multiply by division (Mine all had...
