Having moved house I'm finally getting round to rebuilding a marine tank. As I don't have much time for maintenance, room in my office (too much freshwater) and money (small children) I'm going to bodge it round a Juwel 110 litre - this is approx 30 US gallons. 80 cms, 35 wide, 45 high (I think). I can document this - are you interested? Also, beware, I have patience. I will be surprised if there are any fish in there before March. I am looking to get to 3 or 4 small fish and some low easy inverts. Right now I've filled the tank and checked for leaks, and that the electrics work. I am using the lheater and 600 litres per hour juwel pump from the installed filter. I am NOT using the filter material - this will be live rock and sand only for filtration, and the filter will only become a nitrate trap and limit the water flow. I've also added a 400 litre per hour powerhead I had in my 'stuff box' , but I don't think this is enough and wil replace it with one when I go shopping in Britain next week. I will also try to get a T5 retrofit to go in the Juwel Rekord hood. Last night I dumped in a bag of Kent Salt I had knocking around, and am waiting for it to dissolve. I have the pumps and heaters on Cost so far in Norwegian Kroner - you will have to convert this yourself, according to your local currency. Remember Norway is EXPENSIVE Juwel 110 Kit - 1590 Kroner Kent Salt - 12 quid I tihnk in Britain TMC Hydrometer - 6 quid Rena Powerhead 400 NOK I think 2 bags oolitic sand - 100 NOK. Enogh for a thin sand bed Marine pH kit - 89 NOK For ammonia and other products I am going to use my freshwater kits as I think they work in salt as well. I guess this can end up as a thread, or a mod can make it into an article?
