Apologies, I didn’t mean to be flippant. I was only meaning to suggest usually, where there is profit available to be made, commercial entities will find a way to exploit it, and I imagine once the technicalities of Brexit have been resolved retailers will find a way to supply to all the areas they did before hand.
In your case if this has been the situation for some time, perhaps there are other factors at play (costs of delivery and returns, general logistics etc), though it does surprise me that internet focused businesses like ProShrimp and APS aren’t willing to deliver to Ireland.
Thank you for the clarification, I appreciate it.

My experience is that the situation in Ireland with regard to purchasing specialist goods (such as aquascaping and aquarium supplies) has always been extremely variable in a way that people elsewhere (UK, USA, continental Europe) wouldn't appreciate in the slightest. Goods that anyone in the UK would expect to find easily often cannot be obtained at all here. It's better now than it was ten years ago, but there has been drastic movement backwards in the past year.
For Ireland in general, it is actually the case UK retailers don't like to ship here. That was true in 2018, and it's far more true today. I am unaware of the exact reasoning. Plant and livestock suppliers have told me that it's because they can't guarantee live delivery, but I can buy plants from Aquasabi in Germany and get them next day, so this argument seems spurious at best. The very best UK retailers (like Aquarium Gardens) have never shipped here at all. I'm sure each retailer feels very justified in this and I suppose it's their decision. As a matter of fact, I have never taken delivery of dead plants, and the one time I took delivery of dead livestock, the parcel was sent from within Ireland.
Back to the topic at hand- the Blau DC came from an Irish LFS, which stocks that and the traditional. I reckon Aquasabi sells the JBL, but I won't order from Aquasabi unless I can manage €150 for free shipping, and my aquascaping budget for the year is spent. Luckily the year is almost over.
