Verrrrry oceany :exclaim: :cool: :smile: Looks good Darren. I think a pair of captive bred orchid dottybacks would look awesome in there.

hi Darren,

How do you like the background being blue? I painted mine blue also, and wish that I'd painted black instead. What I've found is with blue, some of the colours (especially blue, purple, pink) get washed out. When u take a picture, the colour just don't stand out. Oh, well, too late for that!

Just my 2 cents!

I hung a piece of paper spray-painted black on the back of my tank. I would recommend this course of action to anyone who hasn't yet painted their tank. It works very well.

Kai,

I really like the blue so far. I am hoping that with only VHO's on there right now I'll get a nice growth of corraline on it. Who knows

A small change to the equipment used on this system. As I sold the MAK4 and 2MD, plus a few other pieces of junk I had around here, I put two Velocity T4's on the tank.

niiiiiiice... man are they ever quiet. Don't even know they are on.

Now to quieten down the flow noise in the overflow. and this will be whisper quiet. Unless someone can come up with some 0dB fans. ;)

This thing is a dream now. awesome flow.

I am guessing about 55x's turnover with the two pumps. Hmm what next?

Ahh .. I was kind of curious as to why you switched the pumps. So it was for noise levels? Are there other reasons as well? How do these new ones compare in terms of consumption?

No turbulence in your sump from the (I presume) increased turnover?

... more questions

Weren't you using a LG2 as the sump return? Isn't a T4 a HUGE step up in terms of flow? Now I'm really curious about how turbulent that sump is.

How hot do the T4's run? I thought when they came out there was some noise on the groups about heat issues (but I could be remembering wrong).

Tony,

noise was the main thing here. I don't have an enclosed stand to hide the pumps in and reduce the noise. So outside they went.

The MAK and the 2MD both were and are awesome. But silence is golden.

There is a fair bit of flow in the sump but the baffles are far enough apart that there really isn't much in the way of turbulence. The flow is up yes. But noise or bubbles isn't. Which is nice. I made the sump with an increase in return pump size in mind. I just didn't expect it to be so soon. ;)

With both T4's going the tank temp has gone up just shy of two degrees. Right now I am sitting at 80. Which is nice. I'll probably add a fan over the sump that comes on when the tank temp gets past 80 this summer. Just need the thermistor and build the controller.

Darren,

I'm interested in the T4 size compared to you MAK4, you got me thinking I should switch out my almost new MAK4 and my MAG18 on my closed loop/chiller.

Question 1 size, they look smaller on J&L pictures.

Question 2 how or does the flow look any different on you closed loop from the MAK4 to the T4.
