CanadaAmanda Posted November 19, 2020 Share Posted November 19, 2020 (edited) I have a 29gallon tank that's challenging. Weeks 2-4 I was doing a water change of about 6 gallons once a week, I'm always treating water with conditioner and adding bacterial supplement with w/c. The filter is a TopFin Silenstream HOB on maximum flow with cut-to-size sponge, a pre-filter sponge, a bag of bioballs (and currently zeolite, but was previously carbon), and I have a Tetra Whisper 1-3gal in there to keep it cycled for another project I have in mind. Tank also has an airstone with a gentle stream of bubbles. Week 1, set up tank, add bag of gravel from existing tank and bacterial supplement over the week (Seachem Stability). Add a moss ball, Java Moss. Week 2, move over half of media from well seasoned (5 years) tank into filter, move over half of fish (1 betta, 3 black neon tetras) add leafy plants and a few small single stem plants. Week 3, Add 3 glowlight tetras, a small handful of and salivinia. Week 4, Add 3 glowlight tetras Week 5, Add 4 guppies and larger stem plant - this is where the problem starts. A couple days after this, 3 glowlight tetras are showing fin rot, one looks to have a bacterial infection, pull out all the glowlight tetras to a hospital tank, treat them. Test the 29 gal, slightly elevated ammonia at 0.3ppm. Do a 50% water change, add extra bacterial supplement, salt at 1tbsp per 5 gals. Ammonia drops. Reduced feeding. Week 6 - One fish has a single ich spot, betta has whiteish coating on head, a guppy has clamped fins. Pull out carbon and treat with Jungle Lifeguard All-In-One (limited choices here in Canada). Lose a guppy the next day. Lose another one 2 days later. Other fish improving. Test water 24h after treatment completed, ammonia at to 1.3-2.6ppm (hard to read the colour on these tests), do a 60% water change, add 3/4cup zeolite in filter, everyone seems happier. Week 7 (this week) - Population is now 1 betta, 3 black neons, 2 guppies and a few bladder snails. Test ammonia 36h after week 6 w/c, still elevated at 0.6-1.2ppm, do 50% w/c. Next day do 40% w/c, refresh zeolite, down to 0.3ppm. My w/c percentages are based on how full the tank looked when I remembered to stopped the syphon, nothing scientific going on there. Add Guppy Grass. Test the next day (yesterday) and the ammonia is at 0.3-0.6ppm, a guppy has clamped fins and betta is being a more aggressive than usual. The water seems cloudier. Add Melafix and bacterial supplement, check for melting/browning plants and pull a few little leaves out. All fish accounted for. All along my tests for everything other than ammonia are normal for my water, a bit softer than my well established (5 years) tank. The plants are all growing, especially the Java Moss. The only plants that were dying were salivinia, I suspect they are sensitive to salt, I yanked the browning ones out to prevent any ammonia coming from them. I think the initial health issue with the glowlight tetras was likely caused by a bit of ammonia due to extra bioload along with some bacterial thing they brought with them (definitely quarantining from now on!) but since then, is it possible that the All-In-One treatment reduced the bacteria in the tank? With plant growth, and first signs of algae on the decor items, the cycle *has* to be happening right?? But why is my water clouding and I'm reading ammonia, even with the reduced bioload and much reduced feeding compared to when the glowlight tetras and 2 extra guppies were in there? Frustrating... With only 6 fish and a bunch of plants I feel like this tank should barely need my attention, and yet the cloudy water screams "test me, change me". With ammonia currently at 0.3-0.6ppm (less than 0.01ppm NH3 based on my pH of 7.1 and temp of 77F), should I be doing water changes or allowing it to stimulate more bacteria and test daily to keep on top of any increase? In this same time period I've also set up a 2.5 gallon tank, which theoretically should be the harder one to manage, and it's golden, with 4 ember tetras and an african dwarf frog, which seems like a higher bioload for the size of the tank. I really wish I hadn't had to treat the 29 gal tank, I feel like it really messed things up. Advice welcome! 🙂 Edited November 19, 2020 by CanadaAmanda Link to comment Share on other sites More sharing options...
