Replacing undergravel filter
I am summarizing the entire process of replacing an UG filter stepwise. Please correct me if i am wrong anywhere.
Step 1. Unplug the heater and let the tank sit for an hour
Step 2. Unplug all the filters and pumps
Step 3. Remove 50 percent water into a bucket1
Step 4. Remove the fishes and keep them in that bucket1 of removed water
Step 5. Add an airwood connected with an air pump into the bucket of fishes
Step 6. Remove the remaining 50 percent water into another bucket2
Step 7. Remove the entire gravel,decorations and filters and put them into the bucket2
Step 8. Remove the old under-gravel filter
Step 9. Set up the new under-gravel filter
Step 10. Put the gravel back from bucket2 into the tank and lay it evenly over the plates of the new under-gravel filter
Step 11. Add 50 percent fresh tap water after treating with anti-chlorine into the tank
Step 12. Add the filters and decorations into the tank
Step 13. Add the fishes into the tank from bucket1
Step 14. Add the remaining 50 percent water from the bucket1 where the fishes were kept
Step 15. Wait for 15-30 minutes to settle the water
Step 16. Start the filters,pump and heater
Just curious, but why are you having to replace the UG filter plate? They usually last a really long time....
UGF? How quaint - <hehe>
I would also suggest that depending on the existing water quality, if you introduce the fish to the fresh water, you should acclimate them slowly and if you do that, I don't know that the remaining old water has much value.
Also, you really don't need to wait an hour after unplugging the heater - even if it had been on, it will just cool in the air instead of water.
Anyway thanks for the suggestions
