I see new tank syndrome written all over this one. Patience is key step one. Step two, Less is more in this game. Everyone is new to the hobby at first and always learning, myself included. We all want to try gimmics and supplements like some mad scientist. Ive had tanks from 10-300 over 40 years and still have to dial it down. There is so much misinformation out there, relax. It can quickly turn from Dr Jekell to Mr Hyde overnight. Im seeing everything from windex to cocktail shrimp. If you want your tank to crash midway after sinking several hundreds to thousands of dollars then it is your dime. Im not saying it cant work, just that so much can go wrong when circumventing mother nature.
Six weeks is the time frame. Sometimes it doesnt take as long but there is nothing wrong with riding it out. The bacterial colony needs to grow, establish, and mature to support life with minimal hassle.
Introducing bait fish (Damsels) works, but there are other methods. Pure ammonia (not windex) added daily has the same affect and doesnt foul the water. If you use any tap water make sure you condition it to prepare it for success. Amquel or Prime can help prepare tap water. You may have to deal with Phosphates later in the game but for now it will work. When testing you should see the natural progression of elevated ammonia, nitrites, and finally nitrates indicative of a bacterial colony in the beginning phases of colonizing. Note I said beginning. Maturity is the time you allow for the colony to handle the cyclical nature of a salt water tank and will insure your success when you go and sink your hard earned cash in some high dollar corals. After your inital cycle Phosphates should be tested and controlled before the green scourge takes up residence. Consistency is the third step in this process. Keeping a log helps stay on top of your husbandry.
There are logical methods all over the internet, so sink some time in research before you throw the kitchen sink at it. It will make your venture successful and you a happier hobbyist. All the best!!!
