Aquarium Dosing is made up of the adding of supplements in aquarium. In saltwater aquariums that usually means pouring of two-part supplements to preserve the chemical balance of the water or the pH-level. Really many elements it is possible to dose in aquarium, between them trace minerals, nutrients and remedies.
In freshwater planted aquariums the Dosing of fertilizers is likewise important, and there exist several liked methods, like EI (Estimative Index), PPS-Pro and PMDD.
How to Dose Your Aquarium Safely
Big principle is dose only that, what you test before. Key advice is avoid the overlap of several Dosing actions. Test the water weekly and adapt the amounts according to the results help to well control the situation.
If all parameters stay stable between the water changes, commonly enough to not dose something. Even so, if the alkalinity seem good one day and fall dramatically after three days, that shows, that Dosing become inevtiable.
Big principle is dose only that, what you test before. In reef aquariums with stony corals the Dosing of calcium and alkalinity are absolutely needed. Magnesium also maybe require to add, if the consumption becomes too high.
Some Dosing devices mix several minerals in one package, what avoids separate treatment of each, and that can strengthen the health, colour and growth of the corals.
More well dose little portions through the whole day then one big pour. Share the everyday standard in as many parts as it is possible help to keep the water values stable. For instance, if the Aquarium requires 6 ml of KH-buffer daily, a programmed doser, that gives 0.25 ml in 24 occasions, works surprisingly.
Liquid fertilizers for planted aquariums likewise act most effectively, when one them dose daily in tiny amounts instead of weekly in big.
Automatic Dosing pumps simplify the whole task. The pump takes the precise amount from the container and distributes it in the Aquarium at the right moment, guided by timer or central system. Like this one avoids manual work and reduces mistakes because of human carelessness.
Such pumps enter measured portions of the liquid in a chamber and release it by means of electrical engine. Brands like Kamoer and IceCap offer programmable models, that install in only some minutes. Some versions fit to add of 1 until 9,999 ml daily, even until 24 occasions.
Automatic dosers are especially useful for folks, that travel commonly or care about complex setups. More important is find the right amount for your own Aquarium than copy the patterns of some other. The main task is estimate, what the Aquarium truly uses, and preserve that.
New aquariums without many corals probably do not require Dosing right away, because yet nothing uses those trace elements. Tubes in Dosing pumps sometimes clog according to the kind of thedosed chemicals, so that deserves to recall.
