ASM skimmer

[YE||0W TA|\|G]

For a 155 gallon tank, which would be better? I have about 150 lbs of rock and 80lbs of sand so this will reduce the amount of water in the tank so its less then 155 now.

ASM G-1 does 100 gallons

or

ASM G-1X does 150 gallons

There is only a 50 gallon difference.

I have a g-2 on my 75 gallon, it is good to get a skimmer rated for 2x the tank volume.

A G3 or G4 would be better. I use a G3 on my 125 and it is OK. A G4 would be better IMO. If you have a little more money get an Octopus or MSX skimmer, they appear to be made a little better.

This one looks promissing and has a great price.

The link does not work. Go to skimmers and look up Vertex IN 180. It's $284!

I use a G3 on my 75.

I wouldn't use a G3 on a tank any bigger than a 125.
ASM skimmers are "ok" but not great unless you MOD them a lot. I also think that the ratings for them are flawed.

Look into this skimmer, best bang of the buck out there IMO

I have a G3 on my 150 and feel like it's too small. I'm thinking G4x

[rgrobe]

I use a G4+ on my 180 with LR, Sand and a 55g sump. I am happy with it. I agree that the G3 at a minimum might not cut it. IMO the G4 would be the way to go.

Get an MSX 200.

Had G-3 on 90g with heavy feeding, it didn't keep water clean. Replaced it by Turboflotor 1000 (recirculating).
But ASM has a large reaction chamber and if you can afford risk of making recirculating and mesh mods, it should help significantly.

I've had an ASM G-2 on my 90 gal for over 4 years and it's worked great. I definitely believe you need at least the G-3 or G-4. The G-1 & G-1X are too small for a 155. JMO

[Capt_Cully]

G4x on about 300 gal system. I wouldn't go smaller than the G3 on that 155. Personally I'd shoot for a G4.

[danecook]

I set up a 75 gallon tank, I have been told for the money, go with the ASM. But, looking on the forums, all I see is how they need to be modded to work. First, would a G1 (rated for 100 gal) work for my setup? Secondly, what kind of mods are necessary, if any?

[MileHighFish]

I'm using a G3 on my 100, I like it. I will be trying the meshmod to get a little more kick out of this week.

[mikeatjac]

There is no way I would use a G1 on anything bigger then a 55. Way over rated as most of the ASM line is. Just to make a G2 work you would have to mesh and gate mod it.

For the most bag for your dollar look at the MSX160.

[betamed]

G4 on my 150.

[Doahh]

G2 on my 90 and it pulls gunk out... Hope to upgrade to something bigger soon (Reeflo Orca or something custom Like the Bubble Matrix? Maybe even an H&S....)

[reefrf]

I use a G3 on my 150g. Works well. But I can see why a G4 may be a better choice.

[mikeatjac]

I met the MSX160 for the 75 for a 155 I would look at a MSX200 or 250.
