I'm doing a fish in cycle right now.

darkcat

Hi,
So I'm doing a fish in cycle right now. And was wondering if I'm doing all right. My fishes are doing really fine!
1. Replaces the decor and everything to the new upgraded tank.
2. Add the same water and make new water.
3. Add Tetra Safe Start (I added about 3/4 of the bottle. I didn't have enough for it. So I'm going to put it if I can.)
4. Add the fishes in
5. Use prime daily 2 ml for my 20 gallon.
6. Continue this until no ammonia, nitrite.
7. Do 50% water change

Here are the questions:
Will this work?
Should I add more tetra safestart?
Do you want the water parameters?
Is it okay to use tetra safestart and prime in the same tank? *
Is 2ml daily okay for my 20 gallon?

Fishes that are in (this will be permanent tank)
2 julii (will add more after this fish in cycle)
5 neon tetras (maybe add more after fish in cycle)
1 baby betta
1 gold zebra loach.

* I added 3/4 of Tetra SafeStart, wait 24 hours then add 2ml of Prime. Did that for about 2 days (not including today and the day I started.)
Any advice is welcome!

What are the current parameters?

I want to advise you to change the water by 50% once ammonia or nitrite reaches 1ppm or higher. What some hobbyists do is change the water by 50% once the ammonia and nitrite both add up to 1ppm (such as 0.6ppm ammonia and 0.4ppm nitrite).

Only add Prime to new water before adding it to the tank. When I fish-in cycled I made the mistake of using Prime to substitute water changes.

You seem to have things under control. :happy: I can‘t bring much info to Tetra SafeStart because I’ve never used it before and I don’t know exact doses etc.

I use Prime just to lock the ammonia so it won't be toxic for the fishes.
Day 1 water parameters:
Ammonia: 0.5
Nitrites 0
Nitrate 0-5

Day 2:
Ammonia 0.25
Nitrites 0
Nitrates 0-5

Day 3
Ammonia 0.25
Nitrites 0
Nitrates 5

Day 4 (today)
Ammonia 0.25 - 0.5
Nitrites 0
Nitrates 0 or 5

Todays water:

From these results I can safely say that your water source contains 5ppm of nitrate. No problem with this; mine does too and I’m fine.

It’ll take some time for nitrite to appear and hopefully that’ll happen soon!

So it's good?
The steps and everything else?

As long as you follow my advice so far you’ll be good to go. :happy:

Unfortunately that's way too many fish for fish-in cycle. Hopefully the Prime and SafeStart will help them survive the process...

Does your step #1 mean that things are being moved from an old tank to a new tank, including a filter or filter media?

If so, was the old tank cycled?

Prime works for about 48hrs. so you should be doing water changes every 48hrs.

I’m a fan of Prime, but. . .

Water changes should not be based on the passage of time or the expiration of the effectiveness period of Prime.

They should be based on the results of daily testing while a tank is cycling to keep ammonia and nitrites at safe levels.

unless its 0, 0 there's technically no safe levels of ammonia (unless low pH/low temp and it becomes ammonium) or nitrite.

Prime renders ammonia and nitrite non toxic for up to 48hrs, while still allowing the bacteria to convert them.

Prime can be dosed up to 5x depending on the ammonia/nitrite levels, or do a larger water change, 75% instead of 50%
Info: Seachem Prime® dosing instructions

OP's ammonia/nitrite levels are low enough to only need 1 dose of Prime with a water change every 48hrs.

If there’s no safe level, I don’t understand your recommendation for 48 hour water changes.

Thanks for the link, but I’m familiar with the instructions for Prime. And I’m still of the opinion that it shouldn’t be used as a substitute for daily water changes if that’s what test results dictate. I’m also of the opinion that Prime shouldn’t be “over dosed” to avoid water changes.

About the OP’s current water parameters, those can change on a day-to-day basis, can’t they?

Yes I upgraded it so I putted all my decors, filter media and etc. However, the filter media was dried up the time I putted it in. So the bacteria can be dead. I don't know if the old one is cycled because I didn't have the knowledge of cycling and I used SafeStart and putted the fishes immediately. All the fishes are still alive.

I'll be doing water changes when ammonia and nitrites add up to 1. Is that fine?

You’ll probably be fine doing water changes at a combined level of ammonia and nitrites of 1 ppm. When I’ve done fish-in cycles, I always tried to keep the combined level at 0.50 ppm or less.

Unless your tap water has nitrates in it, to me it looks like transferring everything over to your new tank has given your cycle a jump start. Or did the water you transferred have nitrates?

Keep doing what you’re doing and I think your fish will be fine! Keep us updated and come back here with questions.

I think the water I transfered had the nitrates.

Transferring water from the old tank to the new one is fine, but there’s really no benefit to doing it.
