HOB Skimmers

[js38311]

I am looking at HOB skimmers for my planned 70 gal mixed reef setup. I know that the use of a sump is preferred to the hang on back variety, but I have certain limitations that are pushing me towards the HOB. First, I have an existing freshwater system that I need to keep under the reef tank. I also have very real concerns about the additional risk of leakage with sumps and having water drawn out of the tank in general.

I am looking at the following two models.

1. Red Sea Berlin Skimmer Classic- Hang On
2. AquaC Remora Pro

Additionally, it appears I'll need to attach some sort of surface skimmer in either case. I saw that Rob referenced the Aquaclear surface skimmer or I might go DIY for it.

And one last thing. Can I "over skim"? Would either of these models even come close to skimming too much with a 70 gal setup?

CPR bak pak dual skimmer

the cpr is the one i think im going with if i dont do a sump. i have heard alot of good things about it also.. not sure if it would be good for 70 gallon or not though

the remora, is probably one of the most recommend skimmers, but since i have never used any of them listed i cant comment on there performance.

as for over skimming, i think its "technically" possible, but i have never heard of anyone doing it of complaining that there skimmer over skims, so i wouldn't worry about that, especially with the units your looking at

the Berlin requires a much larger pump.

I have the regular AquaC Remora on a 12g tank. From the reviews I did, everyone was saying this was the best for HOB skimmers (the pro is prolly better). I wouldn't expect it to keep up on a 70g tank though.

I don't think its possible to overskim a 70g tank with a HOB skimmer- would be very hard.

Why are skimmers so expensive? Also, how much cash might you save if you go DIY?

when i was going to duplicate a $150 in sump skimmer i figured up all the parts, acrylic tubing, acrylic sheets, and all the little tubing. i think my cost came to around $90. now that wasnt including the glue and the little nuts and bolts i would of used. so i figured i should just buy the one already built and not worry about it. now i didnt try and cut costs at all. so depending on the design you should be able to be under $90.. and i feel skimmers are so expensive because there so simple. but there simple to a point that not everyone can make one themself. but thats just my 1 1/5 cents
