Reverse Osmosis(RO) water filtration will also give you a safe (chlorine free) water with a pH of neutral(7.0) or lower These filtration units will strip over 98% of the contaminants out of your tap water creating ideal discus fish water. The spectra pure units that we sell use a solid block carbon filter that is good for up to 20,000 gallons, making it one of the best on the market. These units are extremely easy to setup, using a snap conector that will literally hook up in seconds. I recommend having a water storage vessel (55 gal drum or in our case 1,870 gallons) to store this water in… this allows you to adjust it’s temperature, pH levels etc.
When you are ready for a water change it is as easy as vaccuming your aquarium down to the level you want (20% water changeor so) switching a pump on that is conected to a hose leading from your water storage to your aquaria and filling it up. No buckets to carry… Water change amounts and frequencey depends on your aquariums bioload(how many fish are in it) In say a 75 gallon aquarium with 8 or 9 discus fish (we recommend 1 per 8 gallons as this cuts down on territorial fighting) 2-3 water changes of 20-30% are recommend per week for optimal growth and health. We do not agree with massive water changes daily as we feel that it stresses the discus fish, is lots of work and the benifits do not outweight the input.”
