Asap is my first suggestion. If you have clean, soap free buckets or tubs, try to save as much as the original water as you can...at least 50 percent if possible. pH shock is the biggest danger you face. Then with everything removed such as all life, decor, unplugged heater, etc. Empty the old tank using a pitcher or small bucket. Siphon hoses take too long. Then get the old tank out of the way and replace with new one. Add back your gravel/sand and the saved old tank water 1st and then your plants and ornaments, heater, filter etc. Do this all as quickly as you can. If you've managed to keep half of the original tank water, go ahead and add the fish and treat the rest of the conditioned tap water to refill just as if you were doing a partial water change. Turn back on filters and heater. Wait until next day to feed fish again.HI all,
This forum is proving to be a god send.
My niece was visiting, threw her juice cup, hit my tank and chipped it, it’s also got a hairline crack that’s growing, so I’ve got a new tank as don’t want to risk this one bursting.
Any tips for the change over? All welcome
Thanks
You already have a cycled filter to switch to the new tank. You will need to run them both for a month to cycle the new filter before running just one. Don't add anymore livestock during this time.Thank you. The filter I’ve got currently is not overly suitable for the new tank I’ve replaced it with. I was planning on running both filters temporarily, is that best? The current filter is for a ciano tank and all comes in one big box the height and width of the tank, so wouldn’t have anywhere to fit it into! Thanks again for that really helpful response!
Excellent, thank you again!
