    Hey Y'all! Got a quick question. On my 20 setup with a 5 gal sump, I am starting to see why auto top offs are so popular. My return section in the sump is maybe 3/4 gallons, so I really see the evaporation within a few days. I am planning to make a cheap ATO soon so I don't have to keep...

    Hi, I am gearing up for a massive scale project and I am hoping to find out if there are fairly reliable calculations for water loss through evaporation? If anyone has any formula's which may help I would greatly appreciate any information I can get. I'm sure surface area, air movement over...

    Hi I was wondering if it's ok to do a top off with tap water for one time only because I ran out of RO water and the water mart is closed today and my salinity is pretty high compared to normal so I was wondering if dechlorinated tap water would be ok for one time use

    So this product is listed for aquariums up to 55 gallons. Any reason why it wouldn't work for adding a gallon to my sump once every few days with a 5 gallon top off bucket?? I have a 90 gallon tank.

    I have been doing some research on this subject and I have found many different opinions on this matter. The matter at hand is this...no more water changes OR not as frequent of water changes anymore...this is due to the amount of water you lose to evaporation. Right now I currently have a...

    I have a 29 gallon display with 20 gallon sump. Every fourth day I add around 2 gallon on RODI water in my system. Every time I add the RO water my PH goes down very low to 7.8 or even lower. KH remains in between 8-12. To avoid risk should I add small amount of buffer to the RO water before use...

    Howdy all. I use 000TDS RO/DI in a 7g gravity fed line float to a float style valve in my sump. I know that kalk can be added at a diluted saturation to affect Ph./Ca./DKH. but what are the "ideal" parameters for the ATO water? is there an "ideal" Ph./DKH? or just go by the results in the system...
  18. General Reef Discussion
    I have a question to make sure I am right. So you top-off my reef tank with RO/DI water right? Then do water changes with saltwater.. right? Thanks :)
  19. General Reef Discussion
    Does any one know where I can pick up a decent RO/DI unit for my system? Currently my average evaporation rate is between 5-10 gallons per week so I do not need anything huge. I do not really want to deal with hooking up an auto top off function. I currently live in a rental house so I don't...
