If I had a 46 bowfront, I would set it up with 4 grammas and let them run it.
I have 3 in my 72 bow and I wish I had added a couple more females when the tank was new...

So fun to watch my big male tend to his little harem of 2 girls...

100% the best way to go IMO.
Nano fish in a huge tank looks incredible.

I had a coral beauty it was my last fish to die,tried to save but was too late.got 5 weeks to let tank run empty too make sure the ich is gone,I think that last time i was overstocked and my tank could'nt handle the bioload,so this time I want to do it right,just want to thank everyone for the ideas,keep'em com'in.

I have heard of people waiting 6 weeks and still having ich when they restocked.
Be really careful, we'd all hate to see another crash....

How long do you think I should wait.

As I understand it, there is no real way of knowing for sure that Ich is gone from your system.
You may very well be fine in six weeks, but to be safe, more time would offer more security.

If everyone says 6, maybe 8 weeks would do it?
maybe 7?
No way to know for sure and Better safe than sorry, but hey, 2 extra weeks can also be a long time to wait for something that may be already a non issue.


just thought I'd just mention that waiting 6 weeks is no guarantee, just an estimate.

May want to consider buying or borrowing a uv light and run it 24/7 for a few weeks. Would help with eradicating.... a 24 watt would be plenty for a tank that size, and can be had for in the $80 dollar range.

I run one now and have had no further issues with ick...

Just a thought.

you wait 8ish weeks with a tank that is fishless? what about if only most of your fish died and you have a couple left? can you be sure that the ick is gone if you do not see it on your remaining fish for that 8 week period? it will be scary rebuilding the tank after 8 weeks hoping you didnt miss symptoms along the way.

when I set up my 72, it was fishless for 4 months.

You rush just about anything in this hobby and it'll more than likely turn out poorly.

You wont always see ich, but if its there, it's there.
It can still be present in a fish if the fish isn't showing symptoms, and can live without a fish for up to six weeks OR MORE.

A UV light would probably offer you some security.

can you explain how the uv light works and how you 'dose with it? frequency and duration of use.
