Splatter is right for sure. Especially when keeping nems, tapwater is a bigtime risk. Some locales have tapwater that is suitable for marine aquaria but many locales have dangerous things in the tap. Copper is deadly to invertebrates like nems, silicates are an algae fuel waiting to happen, not to mention that lots of tapwater is full of nitrates/phosphates (again, more algae fuel). Phosphates are another problem in that they will inhibit the growth of stony corals. There are others too, but if you're going reef, do yourself a favor and get a decent RO unit. Its not worth risking multiple hundreds worth of livestock for the cost of one RO unit. When you do purchase one, make sure the one you get has a flush valve/kit installed in it, this greatly prolongs membrane life. Also order a TDS (total dissolved solids) meter with it so you can diagnose it yourself.
How big is this tank Chris? Sorry I'm not very familiar with it.
Tank is AquaStyle 620T from the Aqua One company. Dims are 62 x 72 x 39cm (5 mm glass)
Volume is 130L
The fitted filter flow rate is 550l/hr - so have subsequently purchased a Haga fluval 205 that is good for tank capacity of 200 litres. Output from the pump is 680 litres.
The aquarium - got to stop calling it a tank !!!! is quite deep so the standard lighting I know is not going to be good enough - 2 x 18 watt. So I have already changed the lights to those suitable for Marine Life (white and blue) and it looks quite good. Although I will need to fit another light myself, so some home diy coming up
I have taken the libery and tried to post a pic of it as it stands now. Hopefully get an idea of how I am doing, each step of the way. Would that be of any use to anyone else do you think?
Kindest regards and thanks for the extremely interesting comments/suggestions.
Chris
Oh before I close, I was asking about a skimmer, and have decided to wait till I am in a position to actually start putting corals etc into the tank. I dont really have any worries about the type etc, as I shall use the local dealer again or possibly Internet sources.
