![]() Good question and worthy of a lengthy explanation
![]() Water changes - On any system you should be doing a minimum of 10% a week so on a 150Gallon tank you should be changing 15 gallons weekly, however a lot of people do 25% changes or some even do a lot less. Why water changes with Low Nutrient Systems - Well as the question highlights "low Nutrient" so to help in the nutrient reduction, more so when first starting with the system, water changes are the best way of reducing free radicals (water bound nutrients), but it does not remove structural bound nutrients as will be explained below. Why not just do large water changes instead of LNS - Simply put, all you are doing by changing the water is removing the bad nutrients that have been picked up and bound into the water. However 90% of all nutrients are soaked into the fauna and scaping of your system, such as rock, sand (biggest culprit) and even glass, pipes pumps etc etc. So what LN systems do is build up huge levels of positive bacterias to"EAT" away the nutrients held in the systems structure, this then eliminates the bad nutrients at source. So by adding the Ultra Bak you are putting a very powerful bacterial food into the system that will literally burn off the source of pollutions. This is where the Zeo Lite rock comes in as it creates a very large porous home for these bacteria to live in and as such you create a far great stable area for the baceria to continually thrive. Simply put - Water changes just remove the result of the high nutrients LNS removes the source of the Nutrients. Back to water changes - Depending on the system you are using with fauna depends very much so on the water changes you do. If using the balling method to stop the risk of ionic imbalance 10% water changes weekly are recommended unless you add mineral salts. In regards to Ultra Lith systems, once the system is mature, you only need to do the 10% weekly water changes that are required in any set up, this is just to "freshen up" the water as new salt puts back in a lot of goodness. The other thing as in your case, many of fauna's foods are very powerful and as proven work extremely well, but with all foods you can produce a nutrient sink in the water IF you over feed ( ![]() And this is what is so attractive with using the fauna system, it is made up of parts that you can use as you so choose, you can use the full Lith System for optimal stability OR in your case pick and choose the parts that will help your system, in this case the Bak. Everyone can benefit from fauna, you dont have to be an LNS nut to use it, if you want to rid your tank of structurally bound nutrients then employ a dosing regime of Ultra Bak, and then replace the bad guys with Ultra min-S So what is Ultra Bak? - It is not a bacterial additive, but a specific VERY powerful bacterial food, Bak is so strong it will boost your tanks own bacterial count immensly all on its own and as such is best deployed gradually. If you stop using it after a period of time your system will reduce down to its pre Bak dosing levels so it is not a product you have to always use once started, however to achieve the best result in nutrients for your system a background level is very beneficial, but always remember to add MinS as well so you do not starve your system of ALL nutrients. So What is Min-S? - Min-S is a specific amino acid nutrient, it has been developed to put into the system only positive nutrients. The product is packed full of all the food building blocks that corals and clams etc need to thrive. On regular use you will see a massive difference to your corals, in basic colour and growth, and in animals such as clams the colour will be enhanced significantly. Remember all these products are natural so you are only putting into your system what is found naturally in the oceans Hope that explains everything ![]() Last edited by Aqua-Digital; 01-09-2009 at 02:02 PM. |
