Thats a good size skimmer chamber for that size tank. It gives you quite a few more options.

I would go with the 5 or 6. Even though they are rated for much larger tanks, they still pull consistently from much smaller systems. The NAC6A has a wider neck so the NAC6 would be better than the 6A for your smaller tank. I have not seen any skimmate shots from the 3.5 so I would stay with something proven at this point.

The Tunze 9002 have more good reviews than bad reviews, but they are not the most sturdy skimmers out there and many complain about the noise and difficulty cleaning. Some swear by them and others are disappointed.

Isn't the NAC6 10.5"X6"? I would lobe to get a NAC6 but just worry it won't fit. Anyone have a used one? Good time to upgrade.

Dimensions: 170 * 265 * 500 mm ( 6.7" * 10.4" * 19.6 ")

>>>>>>>>Water Level :9.5"-11"<<<<<<<<<

Does this mean sump water level has to be min 9.5" max 11" ??????

I run it at 7.5 inches of water, so far so good. running it at higher water (~8.5-9.5) level might perform better.

Yes, approx 10.5 x 6 1/4

It should fit because with the 8 in. you have in width, you could slightly turn it and it should give you at least an extra inch. The intake and output are on direct opposite sides on the NAC6 and 6A skimmers.

If you want, I will cut out a 10 x 8 section of cardboard and place my NAC6 on it and show you how it can be configured to fit.

I'll do it tonight and post a pic tomorrow.

BTW, the nac6 optimal water level range is 9 to 11 inches, so if your sump isn't deep then it most likely will be a problem. I run mine at 10 inches but others have had success with levels as low as 8.

its the UK version and the 3000 is about 300lph more output with the same amount of air (500lph +/-). The 3000 would push more water but wouldn't process much more.

I'm not sure if the collar on the intake is 1" or bigger but the 3000 is more watts, so with about the same air, I would stick with the 2500. If you want to go nuts then put a 3/4 in uniseal over the intake hole on the side of the skimmer body and toss in a .040 tunze hydrofoamer (600+lph).

Just my .02

I'm modifying mine right now to use a Bubble Blaster HY-2000. I will post picks when I have it all together. I'm waiting for parts.

 

[reeftivo]

should work great! You may have micro problems with that though because it's 550gph at 45scfh. You may want to put a JG fitting off the air line to tune the air down if need be.

Good luck

Post those pics!

Ive been wondering if my NAC6 is performing as well as it should. I have the skimmer in 10.5 inches of water now. Ive also had it in 8.5 inches with pretty much the same results. Below is a pic with 4 days of skimmate. It is a 50G tank, i would say with the sump my total water volume is 50g. I have 6 fish, Large engineer gobie, Mandarin Gobie, Kole Tang, Royal Gramma, Bicolor Blenny and a small Clown and its a mixed reef. i feed 1 frozen cube a day. Would you say the amount of skimmate for 4 days is about average? Any suggestion to make it perform better?

 

[moondoggy4]

I say it is normal, I have a I-Tech 200 and sometimes I hardly get any skimmate for a couple of days and then on the third day it gos to work.

Thanks for your generosity, but you really don't have to do that. I have decided on another skimmer. Thanks

Next time you take the pump apart to clean it, remove the bubble plate and give it a shot. You'll notice that the bubbles don't fill the body until a couple of inches above the bubble plate in it's stock set-up. If you remove it, the bubbles will fill more of the reaction chamber with no noticeable difference in turbulence. If you don't like it, you can always put the plate back in.

 

[Doe]

Did you take out the whole bubble box or just the plate on the top? I took out the whole box and seem to have a lot of micro bubbles exiting the skimmer but my bubble trap seems to be getting them. Seems to be working well this way but its only been an hr, i will post a comparison pic in 4 days.

Look no plate. Is that like look mom no hands I am assuming the black is a sponge bubble trap.

 

[sneeyatch]

Plate and box - take it out. The skimmer performs much better IMO without it. The box is just too small IMO for it to be effective.

Some have replaced them with a large plate / box and have had good results as well.

 

[reeftivo]

strange,

looks like the output T would direct the flow downward. Wonder what the sponge is for? Maybe the T is blocked at the bottom or the wedge pipe is cut at the sponge. Or maybe the water returns out the top like an ASM. If thats the case then every time you adjust the wedge pipe you would have to get your hands wet.

 

[TheFishMan65]

I thought maybe the outlet was behind the sponge to catch bubbles.

 

[reeftivo]

must be the outlets at the top or near the sponge because it is a hang on skimmer and with the outlet at the bottom there would be no way to completely control micros.
