Hi, just to let you know that I have not done a water change for two weeks. My last water change I once again used Woolworths water. My amonia today is nil and my nitrites are nil even though my one filter has been out of action in this time due to a problem with a knob. Had a bit of algae on some leaves of the plants because sometimes due to my work schedule I have to leave the lights on for 14-16 hours. However, I washed the leaves of the plants and the algae came off. I think I might be about to start reaping the benefits of using good water for water changes and of course the filter settling in.

Hi, I'm new to this forum but I do have a solution for your tap water ammonia problems. my tap water tests a whopping 5.0 for ammonia, yeesh! I have installed a reverse osmosis filter and it takes my tap water from a 5.0 to less than .20. the only drawback to this is a 1.5 gallon holding tank and a maximum per day production of filtered water is 10 gallons. upside great drinking water always available, whats a few bottles of water sitting somewhere while you accumulate enough for a tank change:-)
