hammy Posted September 1, 2013 Share Posted September 1, 2013 Maybe your nitrate start with 100ppm. Changing 30% with salt and di water will lower it to 70ppm. If u change with tapwater, it will always be about 70ppm. U can do small water change to lower down the nitrate. There are a lot of method u can employ Algae scrubber Biopellet Upgrade skimmer Plants But I guess water change is the only one suitable for u Quote 2x1.5x1.5 tank Lighting: AI hydra 52HD Skimmer: Deltec SC 1455 Reactor: Minimax; rowaphos Skimz ; NP biopellets Wave Maker: MP 40 WQD Return pump: Eheim 1262 Chiller: Arctica 1/10 hp A righteous man cares for the needs of his animal, but the kindest acts of the wicked are cruel -- Proverbs 12:10 Link to comment Share on other sites More sharing options...

Kakani Posted September 1, 2013 Share Posted September 1, 2013 Bro dream, how many fish you have in your current tank. What skimmer are you using? How much do you feed your fish? Method to bring down no3: Bio pellet & bacteria dosing Bacteria & vodka dosing Fastest way water change 50% if worry salt use up too fast can purchase sea water from LCK, iwarna, ah beng. $2 for 20L.

hammy Posted September 1, 2013 Share Posted September 1, 2013 Bacteria dosing need strong skimmer. I change water with salt and di water. That's how the hobby is? If not? All method take time. Except water change .

spgohjc Posted September 2, 2013 Share Posted September 2, 2013 Dreams, alternatively you might want to setup a refugium especially for a large tank. Unlike fresh water, we can get it off our PUB supplies, changing only 10% of salt water is no joke! Quote Link to comment Share on other sites More sharing options...
SRC Member jxlex Posted September 2, 2013 SRC Member Share Posted September 2, 2013 After ur cycling is complete, u need to do a major water change to export the high amount of nitrate accumulated... No doubt salt and di water is costly but if u compare the cost i think its still cheaper. Not to mention effective. Water change is very essential in our hobby. Base on ur tank size, ur gross water vol should only be about 125litres. 50% water change is approx 60+litres. for DD salt, recommended is 1kg of salt per 25litres of DI water. So u would probably only need 2.4kg of salt. That would cost u less then $30 for the salt mix!! Compared to the below: 1)Algae scrubber - even diy would cost u ~$100 for setup 2) biopellet - fr + biopellets ~$100 3) bac dosing ~ quality bac cost you $30 at least per bottle and its for long term application 4) carbon dosing ~ long term application Do the math, you know u need a water change now. Btw, on top of regular water change u still need to employ 1,2,3 & 4 (not entirely) over the entire span of your tank's life AND more forms of denitrification methods to keep ur nitrates low too... Your tank your choice.... Quote :: just a noob :: Link to comment Share on other sites More sharing options...
spgohjc Posted September 3, 2013 Share Posted September 3, 2013 You need to be more careful with carbon + bac dosing as they consume much oxygen and alter parameters considerably. At the same time you will need an oversized skimmer for better results. Quote Link to comment Share on other sites More sharing options...
