Aquarium Advice Apprentice
Longtime lurker, first time post. Thanks all for contributing to these threads, which have been hugely useful and informative.
I've gotten to a point in the cycle where things are changing quickly, but some unexpected developments have cropped up. Looking for help on these specific issues, and also any tips for getting from here to ready to stock. My end goal is a healthy tank with enough vegetation to satisfy a couple of aquatic dwarf frogs, a few danios, and a couple of mollys. Thank you!
Current Issues:
Tank Equipment: 20gal hex tank, Top Fin Silenstream 20 Power Filter w/ Large Cartridge, heater malfunctioned during cycling and not replaced yet. There is a large piece of fake coral in the center topped with dead coral on top of a white gravel substrate.
Inhabitants: 1 morimo ball, 1 ozelot sword plant, 3 java ferns. All were planted at tank set up, directly into the gravel substrate. Morimo was removed when the heat was cranked up but was put back a couple of days ago.
I also planted an Anubius when I set up the tank. It stayed stable for a couple weeks, but went downhill after I turned up the heat. Leaves developed brown then translucent patches until it was half pitiful and half green. I left it in until I did the tank change as an ammonia source.
Cycling Method & Progress: Fishless cycling.
At the beginning I put a "weekender" feeder block and about a teaspoon of fish flakes into the aquarium. I agitated the water daily to break up the flakes/feeder block by using a pitcher to scoop tank water out pour it around the edges. I did not add any new food after this.
After about a week, I turned up the heat to 85-90 F. After about two weeks at high heat, I found that the heater was malfunctioning (overheated, melted all the rubber around the end of it). I removed the heater and water has been a steady room temperature of 71 F for the past 2-3 weeks.
Ammonia increased as soon as the temperature increased,
Once the nitrites kicked off, and the ammonia levels plummeted, I started adding 1.5-2 ml household ammonia if daily readings were down to .25 ammonia.
Testing & Levels: Using an API freshwater kit for daily testing, along with some basic strips to test hardness. The charts below are from daily testing.
My Nitrates were consistently at 120 then started fluctuating between 160, 80, 40. Once they went back up to 160+ I decided to do a water change of 50% to also remove the gnarly fish flakes still floating around, and rinse the algae off the coral.
WC: I removed the coral piece and put it in the bathtub, then used a soft brush to lightly loosen to worst areas of algae (not the whole or even most of the piece). I used a pitcher to agitate the water, scoop up a pitcher full of water with flakes, then poured it on any dense algae spots on the coral. I did this until there were no capturable flakes in the tank, which was about 50%. Refilled with same temp water conditioned (tap has chlorine & chloramine).
Immediately pre-change: Ammonia 0.25; Nitrites 2; Nitrates 160
Immediately post-change: Ammonia .75; Nitrites 5; Nitrates 40
-->Then added 1.5ml ammonia
Day after change (yesterday): Ammonia .25; Nitrites 2; Nitrates 160
Today: Ammonia .25; Nitrates 2; Nitrates 80
Hardness readings weekly have stayed @ KH 40; GH 180.

Current Issues:
- NitrAtes are fluctuating between 80/160+ (yes, I did bang, shake, and otherwise abuse bottle #2), and shot back up after a 50% change. Do I WC again?
- Filter is disgusting (gross to me, good for cycling, I know) and may have some mold on the back --> when can I replace the filter, should I clean or rinse it off in the meantime
- Replacement heater recommendations for 20gal tank
- Nitrites and Ammonia still haven't hit 0, though ammonia is bottoming out at .25 consistently (I assume it's still cycling and they will eventually, unless I'm missing something)
- When should water changes be done? (Only change so far is 50% when nitrates stayed at 180+)
