Why a 100% water change after first cycle?

[jessesoto33]

Hey fellow reefers, I saw a video on LA Fish Guy, and I saw him do a 100% water change after setting up a tank before adding live stock, he put sand, and LR for 3 weeks then did a 100% water change.:dontknow:
He said it was to get rid of something, I think he said bacteria, Why did he do this, anybody know?:dontknow:

Who is this LA fish guy? Everyone is posting about his videos and from what most people say he is an idiot.

First, you need to test your water after you cycle it. Check all the parameters especially Nitrate, Nitrite, Amonia, Phospate, salinty, etc.

If the parameters doesn't look good, then do 20% to 30% water change, then test it again and repeat this until you get desirable result.

Then you can start put the livestocks in.:angel:

100%??? Might as well start all over because that would likely make the cycle process a wash.

That's what I thought!

50% if the parameter is bad, the reason you need to cycle a new tank, is to build the mircobacteria in the water, rocks and sand, good and bad and that's the start of life in your new tank.

good point.

I understand, but why recycle?

Because its the green thing to do??? :rofl:

No seriously, I don't think you want to start a new cycle with a massive water change. When I cycle a tank I do a 20% change at the end when the nitrates start coming up, then a 10% a week later. Thats just how I do it though, everyone has their own methods.

I agree, why get rid of 100% of all the beneficial water that you've waited 3 week for!!!:top:

If I remember right, that LA fish guy was still using a wet/dry filter on his main system.

The sad thing is that there a probably a lot of newb reefers who will listen to his bogus advice.

Based on my personal experience alone I don’t think doing a 100% water change at teh end of a cycle would cause another cycle. You may loose most of the free floating bacteria but as long as the new water is good and the tank doesn’t have much of a bio load there shouldn’t be any issues. I’ve done numerous 100% water change on an established tanks and have never had it cycle. Now I also believe that if you have truly completed your cycle there would be no reason to do a 100% water change.

Wouldn't 100% water change mean all the LR/LS would be completely dry? lol

No, that wasn't the case here. he was starting a new tank set up, with a sump. one thing I left out, he replenished the 100% water change with real ocean water.

Smart *** you know what we mean... But if you want to be technical its 96% water change

 

[jessesoto33]

No! it's was a 100% water change, and yes the rock and sand where out of the water, I wouldn't say dry, but damp would be the right word.

 

[Raskal311]

Then its not 100%, that’s what mike was getting at; as long as the rock and sand stay damp the bacteria would be ok.

OK, OK smatallic! but not 96% do the math! maybe 99.95%:aetsch:

There's more than one way to do anything. What works for him may not work for you.
