Leftover items from my decom for sale. All left in storeroom for about 2yrs. Take all for $180 - Artica 1/10 chiller ( just tested to make sure is working) - Salifert Mg, Cal, Kh test kits, brand new, not open before - RODI water system. Need to change the filters - 1/3 bucket of salt and all the buckets of additive you see in the photo - Small skimmer - Refractometer

WTS calcium reactor set for $200 I bought the CR and CO2 tank + JBJ electronic solenoid 2nd hand about 1.5yr ago but never had the time to setup. The PH controller is brand new still in protective plastic wrap. Will include a bag of CR media and new CO2 hose. Don't ask me how to setup as I do not know l because i cleaned the set but never had time to setup. PM me with your contact of interested. Collection is in Redhill area. Come with your own transport as the CO2 tank is still about 3/4 full so it is very heavy.

Does Teck Cheong cut to your specifications? Thanks

Where can i get API Algaefix? Try Clementi 328 but no have... Thanks

Sorry bro, sold. Mod please close thread. Thanks

Try this link: http://reef.diesyst.com/cf/chemcalccf.html Mg stabilizes Ca and prevents Ca from precipitating in salt water. Not enough Mg, Ca will precipitate. Hence, I you are adding all your Ca at one go, (one of the possibility) is your Ca is precipitated soon after dosing. Taken from this article by Dr Randy Holmes-Farley: http://reefkeeping.com/issues/2004-05/rhf/ Magnesium's primary importance is its interaction with the calcium and alkalinity balance in reef aquaria. Seawater and reef aquarium water are always supersaturated with calcium carbonate. That is, the solution's calcium and carbonate levels exceed the amount that the water can hold at equilibrium. How can that be? Magnesium is a big part of the answer. Whenever calcium carbonate begins to precipitate, magnesium binds to the growing surface of the calcium carbonate crystals. The magnesium effectively clogs the crystals' surface so that they no longer look like calcium carbonate, making them unable to attract more calcium and carbonate, so the precipitation stops. Without the magnesium, the abiotic (nonbiological) precipitation of calcium carbonate would likely increase enough to prohibit the maintenance of calcium and alkalinity at natural levels. For this reason, I suggest targeting the natural seawater concentration of magnesium: ~1285 ppm. For practical purposes, 1250-1350 ppm is fine, and levels slightly outside that range (1200-1400 ppm) are also likely acceptable. I would not suggest raising magnesium by more than 100 ppm per day, in case the magnesium supplement contains impurities. If you need to raise it by several hundred ppm, spreading the addition over several days will allow you to more accurately reach the target concentration, and might possibly allow the aquarium to handle any impurities that the supplement contains. An aquarium's corals and coralline algae can deplete magnesium by incorporating it into their growing calcium carbonate skeletons. Many methods of supplementing calcium and alkalinity may not deliver enough magnesium to maintain it at a normal level. Settled limewater (kalkwasser), in particular, is quite deficient in magnesium. Consequently, magnesium should be measured occasionally, particularly if the aquarium's calcium and alkalinity levels seem difficult to maintain. Aquaria with excessive abiotic precipitation of calcium carbonate on objects such as heaters and pumps might suffer from low magnesium levels (along with high pH, calcium, and alkalinity).

You are right about Mg stablising Ca. Depending on water volume, it takes alot of Mgcl2 to raise Mg by 100ppm. Use this calculator to estimate your dose: http://reef.diesyst.com/cf/magnesiumcf.html
