FTS. Can not get one straght on so this will have to do. No phone filter.
Notice the slimer on the 50g' back wall. Zoom in for a look.

Man I love the halide look. I had a 120g with them and loved it. Didn't get the best part and never really played with getting more before breaking it all down but I'm going to be looking for a gieseemann fixture now for my cube build. You see any 36" fixture let me know please. Going back now to read up on this thread to learn more about running a sps system.

No need to zoom in on that slimer as it's spreading like wildfire.

I got down to one nice LT in my 35, nem system, there were 9. It just split the other night again, now I have 8 again.
I remember in the 90's I had these green bubbletips. They just grew large like dinner plate size and never split while stretching out a foot or more from their base.
Pic is from my big screen recliner.

What are the cubes dimensions?
I wish I would have kept all my old halide gear.
This is a 20" hamilton running a 600 watt 7k and a link to my old 120 running halides.
This reflector would have been great over my current 112.

I pulled this from the back of the 150 a month ago. It looks good under the halide at around 200 par right up front.

Are you dosing kalkwasser? Calcium reactor?

This system runs on kalk only.
Kamoer running at 1.5mlm currently keeps alk at 7.5.
You can see the drip into the oveflow in the above pic.
 
I have a few of these HPS bulbs. They are Phillips retrowhite, they are white compaired to the standard HPS yellowish bulb.
What do ya think?
They advertise it as a 2K with blue.

Nice! I have another S51 im going to modify with the different ignitor. The S51 with the HPS was at 449 watts on my meter today.
Also note: I went back to the Ushio 20K. Although less par it has the look I like currently with the edge bars at 50%.
The above pics are the 20K.
 
I'm still waiting for the spectra to arrive...it had few delays...
I already got the HQI ballasts
Cant wait to see that fixture!
It will be interesting to see how many watts those hqi's put out vs the others.

I will update soon as possible!
My GHL power bar have the ability to measure howany watts each ballast will consume.
