Hi everyone , I'm Looking for ideas to secure and neaten up the sump end of my doser tubes ?
Possibly something DIY , here's a couple of pics of my sump , it's the three silicone hoses temporarily tied up , as opposed to just cutting them and leaving them to dangle .

After a rumage through some of my old freshwater bits n pieces I found an old fluval tank bracket , it would normally hold an internal filter , I've simply tie wrapped the tubes to the bracket through existing slots .

I'm now having a little bother with the alk doser tube , the bit of tube that is submerged in my sump is constantly crusting up inside the tube restricting and occasionally stopping the alk mix coming out the end . Does anyone else suffer from this or know of a solution ?

Mine's above the water line but I have the same issue.  I noticed diluting the mixture 50% and doubling the doses helped a lot (I was trying to even out the alk dose through the day).


As for neatening them up, I like your DIY solution but I have one of these and it holds the tubes securely nicely and looks neat.





It came from H20 Aquatics, and is made by Bubble Magus.

Thanks @Amo Manik , I'll may try the Perspex tube and see how that goes to start .
The other option I could have may be to pipe it into my Syphon break pipe for my ATU , I'd been running the tubes below the water to limit any syphoning and emptying of the dose tubes as all are higher that the sump .
@ajm83 thanks yeah I'd seen the bracket , I'll probably order one at some point , I needed something in a hurry to hold all the tubes as I wasn't happy with the way they sat . I don't suppose by chance it's also red sea alk you'd been using ?

TBH i think they're all pretty similar Gav.  Either sodium bicarbonate or sodium carbonate anhydrous  plus a bit of RO water. 

Thanks:

Sodium bicarbonate raises alkalinity a lot and PH a little. Sodium carbonate raises PH a lot and alkalinity a little.

You can turn bicarb into carb by baking it in a hot oven for a bit.
