KH Director Fluid Bottle - how to connect tubing?

[Fisherman Joe]

Hi all.

Just setting up my KH Director, how have you all connected your tube to the reagent bottle or have you put it in another container? Just curious.

Maybe GHL can setup the bottle like Red Sea has with the NO3O4 bottles with a built in doser attachment? Be good.

I drilled a hole in the cap and put the dosing tub down to the bottom

I agree that if they expect us to use the bottle, which they say they do, then they should add an attachment to do just that. I actually put mine in a dosing container.

Have you had any issues? I’m assuming not. I’m about to pour all of mine in a separate container.

@esther I'm doing the same as the folks above and haven't had any trouble with it. On my set up, the end of the line going into the bottle I cut at an 45 degree angle. So if the line bottoms out it doesn't just get stuck to the base. The angle cut keeps it from squaring off and getting stuck to the bottom.

On a side note it looks like GHL changed the bottles to a style that has the ability just to plug right in. (well after you poke a hole in it. @Vinny@GHLUSA is my assumption correct here?

 

[Vinny@GHLUSA]

Yes.
Poke a hole through the cap and drop the tube to the bottom of the bottle.

No issues so far

the cap looks like it has a place but doesn't.. I drilled mine snug to slide the tube to the bottom.. I too cut a 45* on both sides so it doesn't close off against the bottom or side....... after drilling for the size of the tube.. I slightly drilled a little more so its not air tight.. allow for air to enter so it doesn't cause suction..

I dont know why GHL just doesnt sell a cap that has a downward hose and a nipple on the top. That way you can just screw the original cap off and screw on the dosing cap every time you hook up a new bottle.

some things we will never understand.. I think the Calibration 7.5dkh reference solution, I believe should come with it to further calibrate and test.... but nope.. I purchased the bottle today with shipping same price as the item lol

im going to move my sample tube to the very bottom of the Skimmer section behind my manifold pump... see if its more consistent down low and ill zip tie it to a rock or a piece of PVC.. ill report back

I don't understand it either. I guess it would be easy enough to make one from an old cap. The problem is that the plastic these things are made of will typically crack after about two years.

Is it possible to order the reagent tubing from GHL? I’m finding air in the tubing between between the reagent bottle and the kh director. I think it is because I have a tubing quick disconnect installed on the reagent cap. Think the deal is not air tight so some air gets sucked in.

Yes.

I use these laboratory bottles for a lot of things. They come in a bunch of sizes. I use this small 100 ml bottle for the KH Director Reagent. I'm concerned that if you put the tube in a 500 or 1000 ml bottle and it takes a long time to go through the reagent, there will probably be some evaporation that will falsely concentrate the solution. I'd rather just refill the small 100 ml bottle frequently.

Egads, I would hate to have to refill that thing every 100ml. I use 1000ml bottles. The hole drilled in the cap is just slightly undersize of the tube. This allows for a tight seal and extremely little evaporation if any.

Air has to get in to displace the fluid coming out (so it can't be perfectly air tight). If it takes months to go thru that bottle, I bet you'd be surprised to see what can evaporate. But no biggie..... just mentioning what I do.

Just drill a hole slightly bigger than the hose and slide it in. The plastic is pretty thin and might be able to make the hole without a drill. The caps for the 500ml and the 1000ml are the same as well. So when time to change bottles just unscrew and swap out bottles. They don’t put a fitting on the cap because that is an unnecessary connection that could cause an air leak. They want you to use only a single segment of tube so as to keep chances for air in lines to minimum.
