Does anyone know anything about the Blueline bulbs? Especially the 250W 10K mogul "Superwhites"? I found some data by a guy named Dr Sanjay. His data gives the PAR values for tons of bulbs. For each bulb he also gives the numbers using the different styles of ballast. His data shows that...

Im at work and I was planning to drop off my new sump at the glass shop to get drilled but I can't find how big the hole needs to be for the auto top-off float valve. I'm using the Pure Water Club one but their site is blocked at my work. Its that little white float valve. Dang. Does...

I have had a small urchin for about six months. Its got short purple spines and its inside is white. It eats algae and when I have had a Chromi die, it ate that too. I accept that it knocks down one of my frags every week. But recently several of my zoanthids and palythoas have suddenly...

I am going to be deployed and away for 6 months. A 12 year old will be in charge of my 150G tank while Im gone. (sigh) I'm replacing my frankensteined together 10g sump and 15g refugium with a new refugium/sump (30 gallon long) and I was wondering if a filter is really necessary? So far I...

Im freakin out. My 6-stage Pure Water Club RO filter just up and quit putting out water. Is that typical? Anyone had theirs just quit? My wife was trying to fill an ice cube tray and no dice. Now its only a matter of hours before I start to run out of water in the tank. Should I order a...

Hey I got a beautiful open brain about two weeks ago. Looks like this: Its on the sand right under a 250W MH. My tank is pretty deep and it likes being directly under the light better than to the side. I have it between rock islands so it gets as low flow as possible but, if any flow hits it it...

A few days ago I found a tiny white snail on one of my trumpets. They're about 2mm in diameter. Tonight I see there are at least 20 on my center rock structure. I researched it a bit and found that it may be Pyramidellidae snails but I haven't found much info. Are they pests? :shocking:

I have a big fat Golden Head Sleeper Goby that is constantly dropping sand on my open brain and Acans. Both of these corals are recent additions. My tank is six feet long and I have moved them as far as I can from the gobys lair. But still, Mr Bo Jangles will look right at me, take a huge...

Two of my nass snails were rolling around in the sand. It looked pretty intense. One just slithered off and the other is just lying on its back now. Looks as though it is dead or injured. Do they fight? They do seem more intelligent than the other snails.

My return pump's hose has no clamp because the original clamp rusted. When I shut the power off the pump often refuses to restart until I bang on it. While doing this the hose blows off and a geyser shoots up and tries to soak me, causing anyone nearby to laugh hysterically, which sucks by the...

2 Q's. I have a Red Sea Mg test kit. I used it three times and I just don't know if its working right. I don't have any trouble following the directions but I am not getting the blue final reaction. It goes from red to purple. One time when I dumped in the whole ml it got pretty close to...

I have been worrying about the possibility of a flood caused by my auto top off float. I have a pure water club ATO float in my sump/refugiums pump compartment. Recently my filter sock got dirty enough to restrict the flow from the DT into the sump. This caused water to back up in the DT and...

This weekend I noticed my chaeto had gotten dark and is heavily coated with what looks like some sort of dark green algae. The chaeto is starting to die and fall apart. I tried to rinse and rub off the algae, but it doesn't want to come off. I have two 26W CFL floodlights on it. Could it be...

Hey do you guys (girls) typically do hypo or copper on all of your new fish coming in while they're in quarantine? Tangs especially? If you don’t, then how often do they turn out to be infected? I’m getting something good tonight (wahoo) and I am going to quarantine it.

I just picked up two little emerald crabs. They're probably each the size of a dime. They're cool looking. I was going to put them both in my DT. But, I have all sorts of undesirable algae growing in my refugium and was thinking of putting one in there. Seriously its like a scary jungle in...

This guys tests are interesting. Especially how he found that a glass top reduces PAR. -Chris ___________________________________________________________________ Photosynthetically Active Radiation (PAR) measurement In order to keep lighting at constant levels optimal for coral growth it...

I'm upgrading my macro-algae's light today. I just want a little more power .Going from a 23W to a 26W CFL. My options at Target just now were 2700K or 6500K. Which do you all think will work better?

I found this thing in my filter sock just now. I can't find a match online. Im sure its not a stomatella. Its long and slender with spots, antennae, and no shell. And...in the time it took me to log on and write those words it already slipped away into the rocks. I hope it just eats algae.
