Hi
@ChrisD80 I thought I'd try and pick up on your input also.
Was the check valve definitely the correct type, installed correctly and sealed to the hose and good itself; it sounds a little strange to allow air in with and (assumedly) function fine without. Did you ever try it the other side of the dosing pump itself? - I'm not advising this if the rep has suggested otherwise.
You make a good point about the build up of crystallization but that is something I think you agree is easy to resolve as part of weekly maintenance and isn't within the actual pipes itself. As I mentioned before a flush through with some clean, warm water from time to time is a good idea and one easy to carry out also.
Interesting to hear about the time 'slipping' - does it auto correct the time when you connect it to the app?
D-D are normally quite good with customers so hopefully you will get a straight answer from them, fingers crossed.
Hi
@Deano3 I think storage depends on a couple of things - budget and what space you have.
I've used a whole host of different container types along the way, most recently 'TMC EASI-Dose - Dosing Containers' which fitted nicely under a 600 I had and also some 5L rigid containers (that I made sure were safe with the chemicals), with these I used a push-fit bulkhead union fitted through the lid with an acrylic rod down into the container and then simply connected the pipe to the top with a tube-barb connector, although this wasn't strictly required. The 5L is a big size and unsure I'd use them with a small aquarium but if you can find a small, suitable container with lids then is a route of going that doesn't cost so much.
*I did speak with the company who make the push-fit fittings to ask about the insides and tolerance to chemicals etc.
I know there was/is a craze about using Voss water bottles, something that may, or may not be worth looking at.
The more expensive types used mainly with marines are good and rigid but the price isn't wallet friendly, it makes me cringe when I think how much I spent on them.
