JBJ 30 gallon rimless cube

[JBarnes]

Hey guys, hope somebody out there has one of these tanks. I just got mine and was wondering if any of you have drilled the glass that divides the tank and the filter? The China quality returns they put in that tank are pretty cheap and have no articulation. Wanted to put a 1/2" thru the wall fitting to replace those two return lines. Glass looks thick enough but not sure drilling that close to the edge will work out.

Or, if you have other ideas on more functional return line I'd be welcome to suggestions.

Jerry.

Hello,

For what it's worth, I wouldn't bother with modifying the return line(s)--they won't, in the end, be the primary source of healthy movement in your tank.

For my effort, I would concentrate on choosing a good wavemaking source, like an MP 10 or the like; lots of options here that don't require drilling.

Secondly, you don't want too much flow being directed through your filter area--unless you have a really small tank, the return flow will not be a good source of water movement for healthy coral growth.

Hope this adds to your efforts,

Gordon

I did find that a CPVC fitting will fit over the outlets of the thru the wall fittings by sanding the inner diminsion of the CPVC fitting slightly. The fitting is a exact match to the knuckle fitting supplied by JBJ.

However, the pumps supplied by JBJ are pathetic. They are rated at 200+ gph and I get a trickle out of the outlet. I'm going to replace both pumps with a single MAG 5 pump Teeing off to the two outlets. Not sure what they were thinking with those two pumps and two overflows that barely move water?

I got the new JBJ LED clamp on light. Plugged it in and it did not work. Touched the fixture and immeadiatly got a shock. Appears as somebody got the ground wire and power wire mixed up. Called Marine Depot and they are sending me a new light.

The problem is that I don't even think the flow is enough to keep the tank heater happy in the Winter. Got a MP10 on it also.

You must have something clogging your pumps or restricting flow somewhere. I have two of the 266gph Accela's in my NC28 and they put out a lot of flow even with one of them running a chiller loop. 500+ gph turnover rate is more than adequate for a 20-30g tank.

Can't offer you specific advice on the RL30 though, never seen one in person.

Are you going to use a SUMP? what is your live stock going to be like? I would love to see some pictures of the rimless setup.
