jcheek2010 Posted November 28, 2016 Share Posted November 28, 2016 Starting up a 75 gallon tank and I'm almost to the point of filling it with water. How in the world am I supposed to fill this giant tank up??? I obviously cannot use tap water. Should I purchase an RO/DI system? Would that be cheaper in the long run? Do places deliver water? Can I get it at HEB? I've never filled a saltwater tank this large so I've never came across this problem. Link to comment Share on other sites More sharing options...
BornToHula Posted November 28, 2016 Share Posted November 28, 2016 You can buy salt water from a local fish store if you are needing to fill it asap. Long term I would recommend an RODI filter. Today is Cyber Monday, so I imagine there are some good deals on filters floating around. Link to comment Share on other sites More sharing options...
Peter Gott Posted November 28, 2016 Share Posted November 28, 2016 Ultimately I think buying an RO/DI system and mixing your own water is going to be most cost-efficient way to go in the long-run. For smaller tanks you can get away with purchasing pre-mixed water, but a 25% water change on a 75 gallon is almost 20 gallons!

I don't wanna have to haul all those containers. Plus for the initial fill I would either need to buy more or make quite a few trips.Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
Sascha D. Posted November 28, 2016 Share Posted November 28, 2016 Most LFS have RODI and water containers. I believe it's something like $0.50 per gallon, but I would call the fish store of your choice and ask. Five gallon water jugs run between $5-$10 each. It's not uncommon for people to use the RO water from HEB. It's better than tap water for sure. Buying a water filter is kind of a big deal. Right now you could run a line directly to the aquarium and fill it up in about a day. After that you'll need a container for the water to go into. Some people have the room to make 20+ gallons at a time and some don't. It also depends on how much water you plan to change out per month. My aquarium gets a 50g water change quarterly and I go through about 30 gallons of top off every month. Other people don't do any water changes or do them infrequently. There are some RODI filters on sale. I posted a summary of sale items this morning if you want to check it out. Link to comment Share on other sites More sharing options...
+Jimbo662 Posted November 28, 2016 Share Posted November 28, 2016 I always fill for the people I see at the stores filling those jugs. I started out with a 75g/day RO/DI set up. Eventually upgraded to a 150g/day set up. It'll make water twice as fast...there's nothing worse that sitting around waiting for a bucket to fill up. Also, look at getting a booster pump. Most systems work more efficiently with higher psi running into them. With this set up I can fill a 5g bucket in 30 min. Link to comment Share on other sites More sharing options...
Peter Gott Posted November 28, 2016 Share Posted November 28, 2016 Exactly! I've seen people loading their trucks with eight or more of those and I'm thinking, "My gym membership costs less..." Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
jcheek2010 Posted November 28, 2016 Author Share Posted November 28, 2016 Ive been looking at BRS RO/DI units. If I did get one should I spend the extra money to get the one that treats chloramines as well? Couldn't I just use something like Seachem Prime?

Sascha D. Posted November 28, 2016 Share Posted November 28, 2016 Stage 4 RODI 75gpd systems are on sale for $130 with free shipping. Your break point would be at 260 gallons or 37 jugs after the initial fill-up. If you changed out 10 gallons a month, then you would break even on the RODI in 20 months. That is including the cost of filters, but does not include the cost of the jugs. Ive been looking at BRS RO/DI units. If I did get one should I spend the extra money to get the one that treats chloramines as well? Couldn't I just use something like Seachem Prime? The 75 gpd value system says that it treats 3,500 gallons of chloramines. I don't think you're going to run through that much water before the carbon block expires.

I'm happy that you found it useful. That Liveaquaria deal looks sweet but I've already spent too much money. LOL! Link to comment Share on other sites More sharing options...
Juiceman Posted November 28, 2016 Share Posted November 28, 2016 Check your Water Report for your AREA. That will tell you if you need a chloramine system. An RODI system is definitely the cheaper in the long run choice, but it's up to your space and budget. Link to comment Share on other sites More sharing options...

Couldn't I just use something like Seachem Prime? If you're buying, go ahead and get the chloramine set if your area uses chloramines. You don't want to have to mess with measuring out seachem and the filters will be cheaper/more effective in the longrun. I have some 5g containers you can borrow if you're looking to do your initial fill up. Link to comment Share on other sites More sharing options...
jcheek2010 Posted November 28, 2016 Author Share Posted November 28, 2016 Went ahead and purchased an RO/DI system. I live in San Marcos and the travel alone would become tedious so I'll take advantage of the deals! Thanks for your input everyone!
