Now i`m going for a Fowlr. Maybe very few corals in the future. Heaters wont be needed for another year so i can get that later. chillers are not needed.
now i have the chance to get already salted R/o water. This is my only alternative currently to tap water. The water will come from a tank which is already set up and i`m not sure whether this is a bad or good thing. advice? I`m getting the live rock at the end of January ands tarting my cycle then.
Anyone to tell me what i`m lacking? or how to best maximise the products i have currently - thanks in advance
You say the water will come from a tank that is already set up... does that mean a tank with fish/animals in it? If that is the case, then you would be better off with tap water. If the RO water is simply RO filtered, not being used in an aquarium where there are animals, rock, sand, etc... then it would be safe. If you take "used" water to "clean" your tank... you are simply adding the waste of your animals to the waste of the previous animals, and this would become toxic very quick.
As for other equip you may need or have missed... the heater is going to be important to get right up front. Even provided your room temperature is warm enough to keep the tank within the right temp range, the problem is fluctuation. Unless your room is at a constant temp that never changes, the jumps in temp will affect your fish and can be deadly.
I'm still wondering about the water, and if you are planning to work with a source of premixed saltwater... what about freshwater when you need it? A saltwater tank is not going to use strictly saltwater, only during actual water changes. Between changes there will be evaporation, and while the water evaporates, the salt does not. Your new water will need to balance in spg/salinity according to what your tank needs at any given time. Even if doing water changes everytime there is evaporation, the spg/salinity of the new water will still not be able to match that of what's in the tank, or you will end up with too much salt. Always remember the need for both salt and freshwater for your tank and at any given time.
With that said, I didn't see a hydrometer or refractometer listed on your supply list. You can't keep a marine tank without one of the two. This is the only way to measure the amount of salt you are adding, and there is a specific range (1.023 - 1.025) that you will need to stay within. Your hydrometer is something that should be used before ever adding any water to the tank.
If money isn't an issue, a refractometer is much more accurate than the hydrometer, and they last forever if you take care of it. If you work with a hydrometer, find someone with a refractometer to calibrate it for you so you know its accurate. Because of they way they are made, most of them end up "off" and sometimes by a huge range. I have seen customers who's tanks crashed and they didn't discover until after they lost animals that their hyrdometer was off by enough to have over or under salted the water. One of them turned out to have brackish conditions in his tank of expensive and delicate fish/corals all because his hydrometer was inaccuate. SeaTest makes an awesome hydrometer, and is one of the most accurate I've ever been able to find anywhere.
