In the event of a power outage. What is critical to keep my fish alive? Where is the oxygen coming from? I have a power head inside the main tank that points up just high enough to make a ripple at the surface of the water. I had thought by breaking the surface, that this was the source of...

I have noticed that the aquarium water has a smell to it. Also when I stick my arm in there, I got to wash my arm wish soap to get the smell off. I used to run a canister filter but have switched to a sump with skimmer. Do I need to hang a net with carbon in my sump...

I have a 75 gallon tank with a 10gallon sump. I like the Danner Mag pumps. What size pump do I need to circulate from the 10 gallon to the 75 gallon. I tried using my mag 7 but it pratically sucked my 10 gallon dry. The single overflow box could not keep up with it.

My u-tube in my overflow box is always collecting bubbles. I have to run a piece of air line up from the bottom and suck the bubbles out ... along with a mouth full of saltwater. I am sure something aint right here. Is it common to have to purge the air out of the u-tube every week? Is there...

My skimmer does not seem to be working as I had expected. I bought it used from a member. I have a mage 7 driving it. I have never had a skimmer before, so maybe I am missing something here. Do I want the water level in the sump at the same hieght as the outlet port of the skimmer? Do I...

I got little patches (1/2" diameter) of what appears to be tall grass. Well over the past 2 weeks it has gotten worse. I have been somewhat successful in drag a neat over the sand and picking it up, but it comes back. I tried the 3 days no lights, I think the green stuff actually liked it...

I just got a salinity refractometer and it read 1.028. My hydrometer reads 1.024. I assume the refractometer is correct. Would you have expected the hydrometer to be so far off? I even tried some rodi water on the refractometer to make sure it reads zero and it did.

I have had this guy for over a month and I dont think he is growing. I try to hand feed him a brine or mysis shrimp at least once a week. Any ideas? I think he is a bleached out bubble tip. I have vho lighting. The other 2 bubble tips are looking great. alt=""> .

I guess I should have asked this sooner, but do anemone's sting hurt humans? I hand feed my anemone once a week and he looks as though he is trying to sting me (perhaps just tasting), but he soon finds the food (silverside filets) in my hand and directs his interest to it. I have a big hatian...

I want to make a refugium out of a 20gallon high tank, or am I just dreaming? Do you think there is enough room for a skimmer, refugium and a return pump area in this tank? Or should I scratch the refugium and just make it a sump? Why do refugium have 3 partitions as a bubble trap, wouldn't...
