like a 50-70% change? ive been doing like 50% weekly changes and the water never seems to get totally crystal clear like it was when i was doing smaller bi-weekly changes. it looks cloudy like the tank is cycling. my fish dont seems so happy too. thanks in advance guys;)
 
if you run water through the filters before it's dechlorinated it will kill some of your bacteria.
 
I think it's cuz big changes really stir up all the poop and sediment at the bottom that loads of water changes cant fully eliminate.

Filter should catch all the particles after a little while or it'll settle at the bottom again and water should ge clear.

how long do you think it will take a 10gal bucket of tapwater to fully dechlor after double dosed with amquel?? prime??
 
All i can say is 'not long'!

I put the amount of dechlorinator needed in a watering can then fill it with water. Add some hot water from kettle to get it to tank temperature

Leave it for 5-10 mins then pour it in.

Never had any problems.

Nitrite still zero.
 
OK then, so basically if i rush the new water in the tank im killing off my bio, thus making my tank re-cycle causing cloudy water. its really quite simple lol
 
I do minimum 80% water changes on every tank weekly and I've nver had a re-cycle or a mini cycle. I think that what ws said earlier is right. Just make sure that chlorinated waer never touches any of your fiter media or ornaments.

No, the dechlorination is an ionic chemical reaction that occurs almost instantneously. Your bio-culture should be fine. Just add the dechorinator shortly before adding in tap water for each water change and you should have no problem. As mentioned earlier, the cloudiness is likely from you stirring up sediment during the water change.
 
What's your biofiltration? I think not large water changes but possibly insufficient biofiltration might be your problem.

i have a bio chamber thats about 20x12x12. prob 2/3bioballs and the rest scrubbies. this is off the top of my head tho. its a 90 gal.
