TOM Aquarium Overflow Box with Auto Start and Stop, Hosing incl.

I just got this. I did not know that this is not a stand alone unit. It is suppose to be attached to a sump unit that has a pump made to match this. So I have a refugium and a pump but was looking for an "awesome" overflow box. I was misinformed. I don't know if it was me or the way the product was discribed. I see how the "auto start and stop" would have worked if it was attached to the sump pump and tightened with a hose clamp but without the other unit (which cost like $250+), I don't have an overflow box with all the bells and whistles. Hope my information helps others like me. If you are a aquarium guru who knew better than me, than this is my mistake.

UpdateOkay. This unit sucks. Now that I took it apart to see how it works, I can clearly say it could have been made better. Save your money. This unit is made with weak plastic (yes, I considered that many aquatic products are made weak and costs a lot but this is weaker). For $100, it should be stronger, designed better and easy to take apart. I did not break mine but even the instruction book warns about breaking it while taking it apart to clean it. Then I realized two of the parts are very hard to remove. I gave this unit a good try and was disappointed.

Let me say this, if your tank isnt drilled and you want something that does the trick in both a compact and quiet way this is your overflow box. I had the Eshopps PF300 and couldnt deal with the noise, even when I used the modification tips. That thing made all sorts of noises and it was a real pain to get working. This thing is awesome, you simply plumb it (mine wasnt shipped with hoses but i had my own so didnt complain or request them), pour a little water in the resevoir and start your pump. Power goes out no problem, i tested it a bunch of times to be sure it would start back up. Compact no question in and out in the same box cant be beat. Adjustable outlet could be a little better but you are supposed to have powerheads in a reef or saltwater set up so this isnt even an issue worth complaining about. Very adjustable when it comes to water level, I can drop my tank almost 2 inches or I can raise it to the brim, each adjustment can be fine tuned easily. Each click up or down takes about 20-30 seconds to see the change in water level.

Ive been in the fish hobby for nearly 40 years. Ive have probably 5 or 6 different types of overflow boxes through the years and this one just works great. Very easy to set up and to use. And it's self priming! Been using for about 3 months now. If it holds up it will be a best buy!
