Tanks without filteration

[james1234]

Hi guys, i'm new here and from UK.
I have a few tanks setup with breeders and grow outs and also keep Altums which i'm currently growing out.
Just a quick question with regards to growing out, can i run tanks without filteration if i carry out 2x 100% daily w/cs?

[John_Nicholson]

Yes.

Thanks John

Welcome DM from another UK member ,why are you thinking of no filtration ?

[james1234]

Hey Brent. Its just for my growing out tanks for the first few weeks to get good growth and shape (hopefully) and just easier imo having no filters

[Brent1972]

Sounds like a plan mate , as you are going to do two 100% water changes a day your filtration would probably crash anyway as there would be nothing to feed it . I would keep a couple of sponges going in a different tank just in case it goes tits up. Let us now how you get on.

I don't use filtration in any grow out tank. Just sponges.
Good luck!

ChadAre'nt sponges "filtration"?

[Keith Perkins]

Aren't they called sponge filters?

[Chad Adams]

I don't call them sponge filters, just sponges. So no.

I just call my canister filter a canister... So is that not a filter either?

Lol just kidding looks like ur question has been answered, good luck growing them out !

[Chad Adams]

That's correct. It's just a canister.

Sponge filters are well... Filters... And the only kind of filtration that really maters if you take care of your tanks. Back to the point, yes, it would be fine, I use sponge filters in my grow out tanks, primary reason being that they can be great supplementary feeders for fry to some extent as long as they are maintained. Fry will pick at the small bits of food that gather on the sponge, since not all of us can be with our fry 24/7 this can be advantageous. I do not use them because I need the biological filtration, as I do 100% and 50% water changes each day until they get around a half dollar.

I will add that in my 75g with 12 juvies I had to disinfect my filters and while the tank was cycling I did twice daily 95% water changes and I always had between 0.5-1ppm ammonia before the water change. This did not seem to be an issue but still it always bothered me that there was NH3

[Foxfire]

If you had 0.5 - 1.0 ppm ammonia in tanks that were having water changes of 95% twice a day (in a 75 gal) than I do not see how that is possible unless your change water has similar levels of ammonia? Did you, maybe dechorinate the water and you got the false readings from the treated chlorates? My Seachem kit can tell the difference between those so can your test kit tell the difference? Otherwise, that is way too high ammonia levels and I'd think the fish would suffer. You need to look into that - check the source water for ammonia and/or determine if the test kit is reading treated water as a false positive due to reading the chemically treated chlorates.

I'm a chemist so I'm sure of what I wrote. Only chlorine in our tap water was using aged tap water at the time. Without a bio filter ammonia can build fast depending on stocking levels

+1 and unless you drain 100%of the tank water ammonia will still show then return very fast.
