I ran one for many years that hung over my sump, and was sourced from the overflow from the display tank. It used two 150 equivalent cfl bulbs inside polished clamp on reflectors. The world is your oyster. you just need water flowing down a roughed up screen with light on both sides.

I made that to run from the pump on my manifold. It flows into the pipe and down the screen. It gathers at the bottom of the container and overflows back into the sump.

I measured it with my par meter, the screen is getting a little over 100 par on each side. With the edges going down to 80. These lights are cheap. If it’s not I can another another pair. I need to look up the formula of watts per screen size for how much food it can support.

bro great minds think alike. I snuck out to the fish room during a really lame conference call. I ended up using that exact tape, strips were provided with the lights to put on the back. I cut little squares and stuck it to the hard Velcro. I got what I’m hoping is perfect spacing for heat...

@Hockeynut Rob, I’m trying to figure out how to mount the leds. My initial plan was to use small squares of the heavy duty Velcro (the type the ezpass is held up with). It would hold tight, and provide the 1/4 or so of spacing to keep the lights off the acrylic. The 3m tape and CA glue...

Welcome to the club!

So we’ve spoken about two different things here. Bioballs and bio pellets (carbon dosing). I mention it in case any new reefers find this (way off humblefish’s topic) thread. Both are nutrient export methods, that work differently. Read read read! Plastic Bioballs have been around for a...

Reef looks great bro!

Sure, but it’s real basic, you can see everything there. The acrylic is a display box, but it may warp from the lights. They don’t give off much heat so I’m hoping it stays. The best part is you can build what fits your need.

Ok so heres where I am with it: The lights are just taped up. I haven’t decided how to mount them yet.

That’s counter to what I’ve read about them...I guess I’ll have to read some more :)

Wait, I thought bio pellets were a nutrient export method?

It’s good. Every time we add a frag, we’re increasing our biodiversity (For better or worse). The longer my system has been running, the more stable it has become. I attribute it to to increased diversity. This is my view based on experience. Now if I can just keep me away from the tank...

Thanks fellas! I think it’ll be ok for the majority of the reef.

So I lost the hydnophora colonies, and a fairly large cyphastrea in the DT. Most of the sps in the frag tanks either bleached or grayed out. I think I’m mostly ok, nems faired better than expected so far, but I gotta figure out what happened to the oxydator. Also, sorry again @Jon but I...

Crazy thing happens early this morning. Something caused my oxydator to overreact and start pumping out H202. It usually pushes 50ml a day out, which reacts in the vessel but some does get into the sump. It pushed out 1000ml. I lost a couple colonies, and everything is pissed.

And I’ll go to 2” If I need to get a bigger pump

1.5 Matt. I’m hoping that I can keep the flow to both side around 900 to 1k gph. If so, I’m in! If not I gotta get a bigger pump.

I’m going to make a new larger manifold to support the new tanks. here is the main line coming from the pump before it separates to the two manifolds. (Current one and new one).
