Days 4 and 5 of parasite treatments and the sickest discus shows no progress. I’m almost certain at this point he’ll need euthanized. It’s a shame, but it’s obviously suffering and I just can’t take watching him die slowly. The other fish seem much happier and their appetites are ferocious now. The medicine has done it’s job.
On a side note, noticing the dwarf hair grass starting to go insane with growth, I decided it’s now or never on the substrate change. I wanted white sand and all the research I had done recommends pool filter sand. I went to my local pool shop and told the cashier I wanted WHITE. He said I needed zeolite sand. It is not white. . . and at $24 per bag, I wasn’t entirely pleased. Instead of lugging the 100lbs of sand back to the pool store which was twenty blocks away, I decided to stick with what I had. The hair grass will eventually cover the bottom anyway, so the sand color will be irrelevant.
If you’ve been following my posts at all, you’ll probably already know that I do 30-40% water changes every 2 or 3 days, vacuuming the gravel each time. I was certain my gravel was spotless. I cannot even begin to describe the amount of feces and waste that was still buried deep within the gravel substrate. It was absolutely disgusting, and I will never use gravel again.
I poured about 3-4 inches of sand into the bottom of a 5 gallon bucket and I rinsed. Oh my god did I rinse. . AFTER AN HOUR AND A HALF IT STILL WOULD NOT COME CLEAN!!! Deciding it MUST be sand particles floating in the water I let the bucket sit. The water settled and cleared so I thought “YAY!” and started adding it to my aquarium (the fish have been moved to a holding container).
It was like a drop of water had never touched the stuff before. My aquarium looked like 90 gallons of milk. I waited for about 2 1/2 hours before kicking my filter back on in hopes it would clear out some of the cloudiness. This morning (about 11hrs later) it’s only improved by about 25%. . . but it’s progress.
The trumpet snails are alive and burrowing wonderfully. I left two of the Dalmatian molly babies in the show tank during the substrate change. There was one main reason for this… I wanted to see the effect of the cloudy water on the fish. The discus won’t go back in until the water is crystal clear, but at least I would know how soon to start adding the others. The mollies are alive and fine, by the way.
I reintroduced all of the plants except the hair grass plugs. The rest are fairly easy to just stick in the substrate… the grass requires a bit of finesse and I simply cannot see enough inside the tank at this point to do any lengthy work. There is a slight cloud swirl when I work inside the sand bed, but it doesn’t seem to cause the overall clouding to intensify. The plants don’t have any issues staying in the sand which is a plus…
Overall I’m glad I’m going through the hassle of the substrate change. After seeing the debris that was caught in the gravel even after very thorough cleanings, I think this project will definitely help improve the overall health of the aquarium.
