Hello everyone,

I have another question regarding the fishless/seeded cycle for my 50 gallon. (Every time I think that I'm at a stage where I need to ask less questions, I'm wrong! This is definitely a hard but rewarding hobby.)

Despite the many threads on the subject I'm still having trouble figuring out when I can add fish to the tank.

I got 2 filter sponges and 1 large decor from my other established tanks. I did not realize that I should have placed the sponge near the filter intake. Silly me. So they've just been lying around in the tank. I added all three items about 1 week ago. My readings for the past 2 days have been 6.6-6.8 pH (hard for me to tell the colors apart), 0 ammonia, 0 nitrite and 5 nitrate. I'm not sure how much longer I should wait. I plan to move my fish from one of the established tanks into this new one.

Thanks for your help and patience with a newbie x

how long have you been cycling? Your numbers seem like you could possibly add a few fish.

Don't worry about asking questions, cycling can be confusing as heck!

Your readings look ok, but have you been feeding the tank some sort of ammonia?
After a week without, you'd most likely lose most of the bacteria.

Edit: Are those the readings from your new tank?
When you said the sponges were in the tank for a week, which tank were they in?

Thanks Meenu and Lucy. The 2 month-old sponges are from my established 12 and 5 gallon tanks and have been placed in the new tank for about a week now while this new tank has been cycling. Oh and I forgot to mention that I've been feeding the tank with flake food. The tank is also planted.

I hope I'm making some sense. I plan to move 3 rosy tetras and 2 dwarf gouramis to the new 50 gallon tank.

if you put that stuff in a week ago and have not added a food source in the meantime, then the bacteria is dead. It needs to be fed everyday. The time to add fish was the same day that you put the sponges from the old filter in the new tank.

Looks good to me, I'd go ahead and add a few fish.
You might want to vacuum first to get any rotted food out.

Congrats!

Definitely start adding fish, just do some daily testing to make sure you don't have any spikes. As long as you are on top of the water params you can do what it takes to remedy the situation, whether it be a water change or even removing some stock temporarily.

Yay! That's great news. Thank you Lucy, jetajockey, Meenu and Jaysee. You are awesome!!! ;D

Will add the fish tomorrow after vacuuming. I have a silly question - should I remove the foam or leave them in? If I should leave them in, how long should I leave it in for?

Leave them in. I'd say at least a couple of weeks.
