So far So good!!! Updated.
I received my Classic 100-HOB and feel days ago and on time. Assembly was simple and pretty much self explanatory. I immediately placed it in my 150g tank and plugged it in. As expected, it produced a great deal of foam and the foam overflowed quit a bit. I think no matter what protein skimmer you purchase your going to run into the foam overflow problem when you first start your skimmer.Because I was expecting the overflow I had properly prepared. Having a tile floor was a big plus.After several adjustments I was able to control the foam. As a precaution I placed the retaining cup as high as possible. Also as a precaution I unplugged the unit for the first night.The following morning I plugged the skimmer back up and to my surprise the foam was under control. I am still making adjustments to the cup but I expected over the next few days to get it to a permanent level. I am starting to get skim mate and I am sure it will increase over the next few days.At this point, I am extremely happy with the skimmer. It is powerful, quiet, and fits perfect behind my tank and hidden by my canopy. I will update my review in a few weeks.UPDATE; I love my reef octopus. It has settled down and producing so much skim mate. It is the perfect size and is very powerful. What I like the most is it is ultra quiet. I highly recommend this product.

3.0 out of 5 stars Good skimming, horrible maintenance
Reviewed in the United States on May 31, 2020
Efficient protein skimmer when run wet. I am using it on a 125 gallon reef tank.
Pros:good skimming, not noisy, fits in small places if your sump is full
Cons:impossible to clean with big hands. Since the thing sits on the back or side of your tank and is made out of clear acrylic, algae grows like crazy from your tank lights. The openings are only like two to three inches wide and you have to take piping off to get down in it. Worst thing is you don't know it's super dirty until it starts to constantly overflow.
I would not buy again if I could do over for the maintenance issue alone. I'd go with a cylinder one and just plumb it into my sump

1.0 out of 5 stars Defective product - Buyer beware
Reviewed in Canada on August 17, 2022
Do not buy this product. It's a waste of money and the company doesn't stand by their product. The tiny white propeller shaft broke and rendered the protein skimmer useless. This is not about the money. For the health of my fish and coral, I purchased a new pump and had it installed within two days. At the same time, I contacted the company just to see if it was under warranty. The warranty was useless. They wanted $50 to send out the little white impeller shaft. I would take full responsibility if this broke during cleaning but I just awoke one morning and it was hanging in the tank. It hadn't so much as moved an inch since it was installed 7 months earlier. Buy another brand.

5.0 out of 5 stars Excelente skimmer
Reviewed in Mexico on March 13, 2021
En si el skimmer trabaja muy bien, en ningún momento tuve problemas de que tirara el agua como lo hacen a veces los nuevos. De hecho empezó prácticamente el primer dia a producir espuma. Ayuda que la taza recolectora la he colocado lo mas alta posible para evitar problemas y así continua. Conforme quede "asentado" podre bajarla mas a fin de obtener el tipo de desecho que prefiero (una espuma casi seca para que el liquido que se recolecta sea oscuro).

El mayor detalle que tengo en este momento es que la fotografía que Amazon tiene de la unidad en realidad corresponde al modelo 1000, la principal diferencia entre uno y otro es que el 1000 lleva la bomba fuera del acuario, mientras que el 100 (modelo que adquirí y sobre el que estoy escribiendo la reseña) deja la bomba dentro del acuario. Para esto existen otras diferencias de diseño, pero creo es mas tendiente al acomodo de la bomba en una u otra version. Reporte la discrepancia de la foto el lunes por la noche en cuanto me percate y al viernes de la misma semana (12 de marzo de 2021) sigue la misma foto equivocada en el sitio de Amazon. Ignoro si es un problema de Amazon o del vendedor. Por lo demás, la descripción es correcta, pero vamos, en un momento todos nos dejamos llevar por la emoción y ya no vemos lo evidente (en la foto aparte se ve claro el modelo que no corresponde). Otra situación que me hizo no revisarlo mejor es que estos skimmers antes se llamaban Reef Octopus y ahora son Octo. Malamente supuse que en lugar de ser modelo 1000, ahora eran 100, pero no es asi. El modelo 100 viene marcado para 105 galones, mientras que el 1000 en el sitio del fabricante viene para 135 galones. De momento lo tengo en un tanque de 29 galones que espero cambiar en 1 o 2 años por uno de 90 o 120 galones. Decidi quedarme con el por que finalmente cumple las misma funciones que el que creia que había pedido y pues para ya no esperar mas.

Pros:
Muy silencioso! He tenido varios skimmers y creo que es el mas silencioso que he tenido (otros que e usado: Seaclone, AquaC EV 180 y varios muy antiguos operados por aire).
Tiene un buen diseño que logra que no entren microburbujas al tanque
Las camaras están relativamente accesibles, aunque el skimmer es muy alto, con un cepillo largo si se puede alcanzar para limpieza, este puede ser un problema con otros modelos
La bomba se conecta a la tubería del skimmer por medio de rosca, lo que lo hace muy seguro en su operación, cuando usaba el Seaclone, este alimentaba el skimmer por medio de un tubo flexible que se conectaba a una cabeza de poder forzando la salida en el tubo. Con el tiempo y la vibración lograba soltarse y siempre terminaba con cierta cantidad de agua en el piso por ello.
La entrada de agua esta orientada hacia arriba, lo que permite procesar el agua de la superficie evitando la acumulación de material.
La salida también esta muy bien diseñada, no escapan burbujas del mismo.

Contras (o que me gustaría que fuera diferente):
la taza de recolección no tiene forma de regresar el desecho al tanque. Esto es importante sobre todo por las ocasiones en que pueda aventar "desecho" prácticamente sin procesar, agua pues. En estos casos es importante que en lugar de derramarse, pueda regresar al tanque. Aun mejor seria un sistema que cerrará la producción de desecho si se sobrecarga, pero muy pocos skimmers pueden hacerlo.
Las paredes son de acrilico transparente. Dependiendo de ciertos factores, esto puede contribuir a la formación de alga dentro de la unidad.
La bomba que lo alimenta no es una unidad comercial, así que en caso de necesitar reemplazo, únicamente la original funcionara (vamos, no puedes ir a una tienda local e intentar adquirir un repuesto de emergencia)

La unidad de forma general se ve muy bien construida. Delgada en su diseño ocupa poco espacio en la parte trasera del tanque (externa), por dentro la bomba si es un poco molesta sobre todo para acuarios pequeños, en uno de 55 o mas galones, creo que no seria un distractor.

Otros comentarios, mi acuario lo tengo muy ligero en carga biológica y siempre con arena y roca viva. De hecho lo tuve 2 años sin skimmer sin problema. la decision de colocar nuevamente uno es por que creo que trae otros beneficios.
