Apologies if this has been answered before, I searched and saw some very old posts on it, so thought I’d ask as the tech has moved on?
I have previously had a marine tank, I currently have a tropical setup in a Juwel vision 450 and want to convert to Marine. 1) I have a fluval 407 external filter, is that enough? Add another additional filter? 2) should I add the Juwel protein skimmer? 3) I have the Juwel twin T5 light units x2, is this enough or convert to LED? 4) And still run a UV light?
As far as I know, we no longer have any marine fishkeepers on this forum. Hopefully I'll be proven wrong and someone may be able to answer your query. However, if not, it may be worth having a hunt around for a specific marine-keeping forum. [See my response to https://www.fishkeeping.co.uk/modules/ ... wtopic.php?topic_id=41155 for some potential pointers to some.]
