I added Tretra brand Start Zyme to my brackish tank when I set it up. I was wondering if anyone would have a good estimate on how long I need to cycle before adding fish. I purchased saltwater and freshwater from the local petstore. It has a brand new Marineland filter system running with about an inch of sand in the bottom. I have read the cycle posts on this site. I understand that my ammonia and nitrite has to be at 0 but for how long before adding the fish.

Also I am going to add some aquarium salt to a 25 gallon tank of goldfish. Being that I am new to this hobby, I was not aware of the cycle. I am doing a 50% water change tomorrow but am not sure how much aquarium salt to add to it.

Any advice would be welcomed.

it should take about 3 weeks and hen when its safe a week of steady good water parmeter levels. to be safe of the ammonia spikes that could happen in that week of initialy being a cycled tank. so about a month and your ready to put fish in. as for the goldfish i wouldnt put the salt in they dont need it. i never put it in with my goldies and their fine for a year now their growing so well and happy. s for the salt adding to the brackish tank. i believe its a teaspoon per 10 gallons, but i might be wrong. so wait till someone with experience in brackish water tanks to confirm it. i hope i helped feel fee to ask more questions and good luck

goldfish should never need salt unless they have fungis or soem thing els salt can fix if you add aquarium salt that would make that a brackish tank and there fresh water. i do have goldfish in a brackish tank but i have no other tank for them at the moment.

I have had two fish die and one that was acting really bad and another that has clamped back fin. They're all not eating. As they where about four days ago. So how is it that I treat them with aquarium salt?

a salt bath would get their fins unclamped. just put 1/2 ounce(15 grams) of table salt per quart of water. put the fish in the solution no more than 20 mins keeping an eye on them the whole time. then take the fish out. and return it to the tank. for the not eating part there are some questions i need you to answer. what are your ammonia and nitrite levels.(petco and other fish stores will test your water for you for free just take a half a soda bottle full in with you). how often and how much do you feed your fish. how often and how much do you do water changes and vaccume your gravel. how many fish are in the tank and how big is the tank. plzanswer these questions fast or i wont be able to answer them till tomorrow.

If you put salt in an aquarium, remember that it does not evaporate like water does and can thus reach high concentrations. To measure salt concentration, you will need an hydrometer or refractometer. That's one good reason for not using salt in a freshwater aquarium; another good reason is freshwater fish and plants don't need salt. If they did, they would be called marine or brackish water species. Mollies and some puffers do prefer brackish water, but it's important to get salt concentrations correct. The salt bath as suggested above helps avoid salting the entire aquarium.

It was a long time ago, but the first few dozen aquarium fish I killed all got plenty of medications for a range of diseases. Medicating fish and aquariums never works if water quality is poor. Establishing the nitrogen cycle, doing weekly partial water changes, and avoiding over crowding and over feeding all but eliminates the need for medications.

So here is more info.
I have two fancy goldfish, my $ .13er from petsmart was a feeder but daughter liked it and a pleco in a 25G. I was thinking of placing them in all in the 5G Hexagon that is testing with good water parameters. That tank did have my frog in it until I upgraded him. What do you think?

if the 25 gallon is really that bad ok but how big is th pleco if its small then yeah the 5 i fine but its gonna be really cramped but if its big thn nope it wont work. they have barbs that come out behind their cheeks and those will kill or injure the goldies if they run into them accidently. but like i said if the plec is small then its fine only if the 5 gallon is cycled and has good testing results

I did a 50% change in water and the ammonia is down from 3 to a 1. I am. Going to just continue with 25% changes daily and see what happens. I got a gravel vaccuum from walmart so I will do a cleaning tomorrow with the 25% change.

Thank you all for the advice.

Try to pick up materials from the surface of the substrate, but deep clean only 1/2 of it during any week. The beneficial bacteria live in the substrate, and you should not remove all of them.

I assume you're doing the partial water changes in an aquarium that contains fish. That helps dilute toxins so the fish are more comfortable, but it will also result in a very long time to establish the nitrogen cycle. If the aquarium has no fish, don't do any water changes until the nitrogen cycle is established.
