Cmlee Posted June 21, 2015 Report Posted June 21, 2015 My nitrate has been at the 40 - 80 level . Water changes are not efficient as tap water is at 40 and too much water changes kills shrimps . What should I do to reduce nitrate? Or I just ignore it? Johnnydok 1 Quote
OMG Aquatics Posted June 21, 2015 Report Posted June 21, 2015 As shrimpie said, RO water would be best. Another option could be getting a large container and filling it with your tap water then run a filter in it with a nitrate absorber. Should be such filters like these. Quote
Cmlee Posted June 21, 2015 Author Report Posted June 21, 2015 Can you recommend a nitrate absorber? Quote
OMG Aquatics Posted June 22, 2015 Report Posted June 22, 2015 Can you recommend a nitrate absorber? That I have no clue. You would have to google search and test the products as most people use RO water or their tap is perfect/near perfect Quote
shrymprdan Posted June 22, 2015 Report Posted June 22, 2015 Cmlee, How "planted" are your tanks? Seems to me that plants may be able to absorb some of those nitrates. I don't want to bring the dreaded "duck-weed" up without the following disclaimer: IT GETS EVERYWHERE! However it is a nitrate hog... What about some other floating plants. Salvia (where allowed), Amazon frogbit, red root floaters. If you're in the market, check out Han Aquatics. Quote
Cmlee Posted June 22, 2015 Author Report Posted June 22, 2015 I have these floating plants but nitrate does not go down Toads74 1 Quote
RyeGuy411 Posted June 22, 2015 Report Posted June 22, 2015 Are you using tap water for your top offs? If you have those nitrate loving plants and you arent adding more it should be going down. Quote
Shrimple minded Posted June 22, 2015 Report Posted June 22, 2015 Purigen? http://www.seachem.com/Products/product_pages/Purigen.html Quote
Dendrobatez Posted June 23, 2015 Report Posted June 23, 2015 Purigen doesn't remove nitrates, just the organics that lead to nitrates - I'm not sure there are any products that remove them directly. To remove them you need anerobic bacteria which would be found in a deep sand bed set up or a slow flowing filter with larger porous lava rock type media, water changes, or fast growing plants. If you do some water changes and the add purigen it'll help prevent build up in the future but it won't lower them directly. Sent from my VS985 4G using Tapatalk High5's 1 Quote

Soothing Shrimp Posted June 23, 2015 Report Posted June 23, 2015 What about this: http://www.petsmart.com/supplies/filter-media/api-nitra-zorb-aquarium-filter-media-zid36-16970/cat-36-catid-300089;pgid=abtCWvHQ1QlSRplZ09QDlf4G0000zX8Z9uJM?_t=pfm%3Dsearch%26SearchTerm%3Dnitrazorb Quote
Faralon Posted June 23, 2015 Report Posted June 23, 2015 Buy an RO/DI system, you won't regret it. I have 30ppm nitrates out of my well water. 0 nitrates coming out of the DI canister at the end of the process. Plants will also eat Nitrates for energy. Some more than others as mentioned.

Faralon Posted June 23, 2015 Report Posted June 23, 2015 I purchased the RO/DI unit from BUlkReefSupply that comes with a drinking water attachment and set it up under the sink for drinkable RO water. I ran a line from the main filter down to my water room and mounted the DI canister there. It'll cost some $$, and DI refills are roughly 20$ shipped, but they last reasonably long.

Faralon Posted June 23, 2015 Report Posted June 23, 2015 Ever see those labeled on hotdog packages that say "no nitrates"? You don't want to be drinking 80ppm tap water. Sent from my iPhone using Tapatalk Quote
Faralon Posted June 23, 2015 Report Posted June 23, 2015 Oh, and due to my higher nitrate concentration I do have 5ppm nitrates out of the drinking water, RO side. Although the membrane is almost 3yrs old at this point and I should replace it. Sent from my iPhone using Tapatalk Quote
