View Full Version : Does the Mini BK180 come with a skimmer drain?

Hey Scott, I totally forgot to ask this but does it come with a drain? I suppose I could have waited until Tue (when the skimmer arrives) but what fun would that be?:) I plan on ordering a Davy Jones Locker from Avast for the skimmate, and was wondering if it comes with a drain. If so, what size is the tubing? Thanks!

The don't. They have a hole in the drain cup with a removable rubber plug in it. You could fine some rigid tubing and glue it in or carefully tap the hole in the side of the cup and add a fitting. It's a metric sized hole too. You could likely take the cup to Lowes and find some PEX tubing in the plumbing section that would fit in the hole with some persuasion.

That said, unlike most skimmers, the BK Mini cups are very heavy and just sit on the skimmer. You need need to thread them off to get them off the skimmer. Just life which makes draining the cup pretty simple. That's what I do with the Mini 160 I have on my 100 gallon at this point.

I think you will love the skimmer. I have been constantly impressed with mine. It's the best performing little skimmer I've ever had my hands on. I had a brand new Aquamaxx Co1 that I bought for this tank and it was OK. I bought a used Mini 180 which turned out to be too large for the skimmer compartment on the 100. I then found a near new Mini 160 which I jumped on. It works amazingly well and has really impressed me.

Thanks Scott. I'll figure something out with the drain. Perhaps some Weld On and a piece of an acrylic tube?

That would. I'd look for PVC though because the white material used on the skimmers is PVC and the drain hole is drilled into the base of the cup which is also PVC. You could then use standard clear PVC glue.

Ahh didn't know the hole was in the base. How large is the hole?

It's metric. I am not 100% certain. If I had a caliper here, I could measure mine for you but I don't have one here to check with. It's just under 1/2" though. I have a caliper at my office and if I remember to grab it tomorrow, I will bring it home and measure it for you. It's digital so I will need to grab some batteries for it on the way home.

No worries at all. Please don't go out of your way as I should be receiving the skimmer on Tue. Thank you, Scott.

Glad to help. You will love the skimmer! I just cleaned my cup tonight. That is one thing I do love about the skimmer is that the cup just lifts off. It makes it way too easy to dump the cup unlike my Supermarin 250 that is connected to a 1.5 gallon jug since that cup needs to be unscrewed to remove it.

Thanks Scott. So the cup doesn't screw off like the Vertex Omega skimmers? Ahh, interesting!

Nope. It's really heavy and just lifts straight off which makes it really convenient.

Ok, sounds nice! Wonder if it's some sort of compression fitting?

No. There is a special o-ring seal in the bottom of the lid. The water line in the skimmer is best at about an inch below the top of the body (there is a line on the body for where to set the water level) and it's just foam rising up from there. The weight of the collection cup combined with the way the cups PVC bottom is milled to fit into the body egnerates enough compression on the o-ring to form a good seal to prevent skimmate and foam from leaking through. I use a bit of silcone grease on all my o-rings including the one on my Mini 160's neck. You will see tomorrow. The collection cup on this skimmer probably weighs as much as the complete Omega skimmer minus the pump. I think you will be pleasantly surprised. It's built like a tank and weighs far more than you might expect.

Maximus

Sounds great. I have some silicone grease left over from my last skimmer that I will use on the O ring. Thanks Scott!

Didn't glue it it was one of those barb that pushes into a John guest I think it's a 3/8 I just wrapped it with Teflon so no glueing.

Wow, just opened the box and this thing looks like a work of art! Cleaning the cup will be really easy as you just lift it off the base. Scott, is the skimmer supposed to come with an ozone port cover? There's a hole next to the Venturi and I assume that's for ozone? It's uncovered and I cannot find the little nipple that's supposed to plug it. Thanks!

No cover and none needed. If you don't have the ozone tube connected (which you won't), it will draw water in through there as well as through the nozzle instead of just through the nozzle which doesn't change the pumps perfomrance at all. The pump can only draw so much water anyways because the flow is dependant on the RPM of the pump. As such, the pump doesn't care if it comes through the ozone port or the nozzle. Heck, it might even help in reducing salt creep in the venturi port having a bit of water come in through the ozone port.

Beauty and a beast! :thumbsup:

I've been really happy with the Mini I have on my new tank! It performs every bit as well as the Supermarin on my big tank and infinitely better than the SCA and the AquaMaxx Co1 that it replaced. These are great little skimmers. You will really appreciate it once you get your tank up and stocked.

Scott, what is the recommended water level for the skimmer? I am running it in a Synergy sump with an adjustable baffle so I can go anywhere from 6" to close to 10" on the water level. I plan on breaking it in now and will add skimmate from my nano tank.

I also noticed that when I go above the recommended water level, the cup leaks a bit. Is that normal?

Maximus

I couldn't wait so I put it in my sump, added a small cup of skimmate from my nano, and voila! Haha, where or what is this mythical process called break in?:)

I also wanted a set and forget skimmer so I went with the mini 180. I understand that the rd3 speedy is an awesome pump but I just wanted a skimmer that was simple to set up and not have too many options as I'd be driving myself crazy changing water level height and wattage on the pump. I also adore the Askoll based pump.

Man I can't seem to get a foam like that on my bk200 mini. How do you get a dry foam like that? Do I have to lift mine up a bit.

If your wedge pipe is wide open, you may need to raise the skimmer if you have the standard Askoll based pump. A half in should make a major difference. Also, is your 200 one with the RD3? If so, what speed are you running the pump at?

Rd3 at 35watts

35 is a bit high. I would dial it back to 30 watts and try raising the level in the skimmer. The lower wattage will create more contact time and thicker slower moving foam. That said, if your load is really low for the skimmer and the skimmer is oversized for the display, you won't get as good of foam as you could be getting. Also remember that he added some skimmate to his sump so there is an abundance of dissolved organics in the water which is needed for good dense foam.

LOL! I meant 30 watts. Not sure how I typed 200. I went back up and edited my post to correct that so somebody else doesn't get confused. I also meant raising the water level inside the skimmer. Not raising the skimmer. When you slow the pump down, your water level will drop inside the skimmer. You will likely need to counter that by raising the line where bubbles turn to foam back up to the level line on the skimmer body. You can raise the level by rotating/closing the wedge pipe a bit.

Once you lower the pump speed, the foam will be more dense but the water level will drop in the body. Thus you will want to adjust the level again to compensate for the lower pump speed. You will want the line where bubbles turn to foam at the water level line of the skimmer body which is about an inch or less below the white PVC collar that the cup sits on. As I said above, 35 watts is a bit high IMO for that skimmer. Reducing the pump speed will increase contact time and also allow the bubbles to rise slower. They won't burst as fast in the neck and the end result should be more dense foam.
