Hi all. I'm not so much new to saltwater, probably just out of touch with current methods and equipment. I have short term memory issues so often forget much of anything I've done I recent years.....including my fish keeping exploits! Anyway, after a 3 Yr break I treated myself to a drop off tank for Christmas and did a freshwater fully planted set up. However, it doesn't challenge or hold my attention. After years in the hobby it's just too easy after keeping a mixed fish/sps tank.when discussing my intended change back to saltwater with my lad, also a fish keeper, he reminded me that I had multi stage r/o, mixed my own water, had 4 channel dosing, auto top up, refugium etc, none of which I recall.
So, my questions are simple. On the clear seal drop off I have a relatively small 2 chamber sump. Lighting wise I'm not sure what to go for. I am on a low side budget of £800 for lighting, wave makers, atu, possibly doser and upgrading my return pump. I've also got to factor in maximising my small sump space. I'm undecided on a skimmer at this point. I will be using live rock and stocking will be more focused on the corals than fish. Tank capacity is 250ltrs. Thanks in advance for any suggestions.
