On Sunday I did a major cleaning, 16 gallon water change on my 29g tank, a little more than 50%, but I didn't check the nitrates, they're always about 5-10ppm due to the plants. I used to dump the buckets of dirty water on my shrubs, but my gardenia is dying, and I think it's due to root rot from all that water. I did put some tank water on my flowers.did a 50% water change to my 75 gallon fish tank. The total dissolved solids were over 800ppm so I figured it was time. I used my python and put the water into 5 gallon buckets out in the yard. Mixed in some fertilizer and my nematode drench concentrate with each bucket full. Got everything fed and watered! And a good drench of the nematode control solution. Three birds with one stone!
When I finished stripping down the tank to sand I discovered I still had four Kuhli loaches. A couple of them are almost 8 years old.
