I have a 400w MH on a magnetic Hamilton ballast. Plugging the ballast into my Kill a Watt, it reads 400w dead on. I don't know what other ballasts do but this one draws 400w to drive a 400w bulb.

Right, no way you want to pump it both down and up.

The only way to do it without a sump is to put the skimmer over the tank so it overflows back into the tank as fast as the water comes in. You...

Two options, one already rejected - buy a nice piece of oak, attach it to at least two rafters thru the drywall ceiling, hang the pendant from that.

The other option; find I nice cheap floor lamp...

I got two gulf stream 2's up and running two weeks ago and now one of them no longer works. Probably the prop is hitting the front of the cage. It makes a loud racket that can be heard in the next...

I have a 500 in sump, very happy with it. As stated above it needs a large pump which means higher electric bills. I am very happy with the performance and the skimmer is quite sturdy.

Wait, does your skimmer return to the sump or directly to the return pump? If the latter then you have a race condition no matter what - unstable.

Divide the sump in two parts with a permeable...

PVC trim reef safe?

Has anyone used PVC trim in their tank (or even around it)? Is it reef safe? I'm thinking it would be easier to use than acrylic. Here's a link:...

No experience from me. I assume because of the coloration they will not peacfully coexist with yellow tangs so I've avoided them.

When on a timer you do indeed have to futz with the output, but I only do it a few times a year. I lose about a gallon more water in winter than in summer.

Reefman, what kind of pump are you using for the auto topoff? 3/4 tubing seems a bit much, you want the output to run at a drip drip drip rate, not a garden hose rate.

Keep it simple, you don't...

Is the water dripping into your tank clear or cloudy? If its cloudy the precipitate could easily swing your alk too far. If it's clear it would be hard to add so much that it hurts the tank.

The essential detail here is a 150w 20k looks a lot dimmer than a 150w 10k or 6k. 20k's are dim and blue.

As I understand your idea, it has 4 hi-par lights shining from a line along the length of...

Personally I prefer actinics to 20k's. In my opinion a mix of 10k MH plus actinics beats 10k MH plus 20k MH both on looks and bang for the electric buck.

With 300w of the MH coming from low-par...

Spectrum-wise I think it would still look good with 4x80. But intensity is going to be marginal for some purposes and more actinic could help make up for it.

Intensity rule of thumb for SPS and...

What is the size of your 220?

I would not use 5.5/6.5 Ks in any setup; do they make anything look good? With that much actinic I'd use 10k MH across the board, they put out more par than 14k...
