I fully understand Goldie about the costs of the filter. I ran freshwater tanks for many years on tapwater with conditioner. When I converted to saltwater I used tapwater for over a year because I did not have access to RO
water nor did I have the funds to buy a filter. I did not think I had to many problems with algae in the tank but one day I bit the bullet so to speak and invested into a RO
filter. WIthin a month I noticed the water was clearer and the algae that I did have was reduced.
Think of the purchase of teh RO
unit as more of an investment than an outright purchase.
You should be able to find a good 3 stage RO
unit for less than $200. I got my unit off of a guy on ebay. AquaFX is one of this sites sponsors and they offer RO
units aswell. AquaFX has a three stage 50GPD unit for just over $130 after their 10% discount.
There are members here that dont use RO
units and have very nice tanks. Some buy RO
water from wal-mart or other sources and others use tapwater like Adrian.
