  1. First trim. The back is pretty full from all of the culture cups I used, so I did not replant. There seemed to be a good bit of GHA starting. I'm not sure where it got introduced. Perhaps it started to overtake due to my Co2 tank being empty? I replaced the Co2 and blew all the detritus into the water column with a bulb, then knocked back the stems and Cuba to promote new growth. Sept 28th, 2023
  2. Another 10 days of growth, Aug 27th 2023 Not sure when I should do the first trim and re-plant.
  3. All filters have pros and cons. HOB's provide the worst filtration next to air driven sponge filters. That's just an issue you're going to have to deal with, if you chose to run one. I also said in my original post to use a cut to fit sponge. See? This takes care of the bypass issue, once the basket is removed. For the record, I like having a surface skimmer. It removes a lot of biological waste that would otherwise build on the surface and form a protein film.
  4. Buy your media bags on Amazon. There's hundreds of manufacturers with all different dimensions and pore sizes. You can get a 10 pack of whatever your looking for, for around $8.
  5. For HOB, Tidal is best in class (IMO). It's self priming, has a sicce pump, and skims. I wouldn't worry about a canister or media types, as you're not going to max out any filtration with a 9g tank. A simple sponge cut to fit will be fine. As for lighting, it doesn't really matter without Co2. Don't believe that adding more par is going to result in more growth. Just look for something with a plant spectrum. Kelvin, lumens, and wattage mean absolutely nothing. I would put the $30est 12" light on the tank, and that should get you close.
  6. Sorry for the late reply. Feel free to follow along.
  7. Moving to the journal section to keep an online tank record. Equipment: Lifegard 7g full view Chihiros B series 30cm GLA paintball reg and atomic diffuser Aqueon Pro 50w Seachem Matrix 1L Brick sized coarse sponge Setup and dark cycle start Jul 27th, 2023 Planting day Aug 7th, 2023 10 day growth update Aug 17, 2023
  8. Nitrifying bacterial colonies can double in size in a matter of hours. Pull the filter media and/or sponge out of the HOB, rinse it off, and just toss it in the new canister. There's no reason to run them both at the same time or squeeze old detritus into your new clean filter.
  9. The last time I looked into it, I was using it in a low tech planted setup. My tap water is right around a 7.5 ph, so it is inert in MY low tech tanks, and that just stuck in my mind.
  10. They're the exact same. What makes you believe that GHA, GSA, BSA, etc, photosynthesize using a different spectrum in the presence of salt?
  11. Sorry, I misremembered and was partially incorrect. CaCo3 stops dissolving and becomes inert around a pH of 7.4. If you're water is much more acidic, say 6.4, it will help to buffer it to that level. It absolutely will not raise it to 8.2 like caribsea claims.
  12. You can't really "stall" a cycle. At this point, you are finished, there's no question about that. As for your stocking choices and testing methods, both could probably use improvement. Api reagents settle out of solution. Make sure you are shaking those bottles for a solid 30 seconds each before testing, and holding them completely vertical when counting drops. Also double check that you are filling the test tubes correctly, with the bottom of the water curve touching the line.
  13. Very small or labyrinth. Either way, just make sure your "ecosystem" really is one capable of substaining what ever you place in the tank.
  14. Every tank has ammonia present. It's a universal constant. What we need to pay attention to is the concentration. In OPs case, 1ppm is very high from the tap. Anything over a 25% WC at that concentration I'd consider harmful. Aragonite is completely inert. It's fine to use in both FW and marine applications. Keep in mind that most non aquasoil substrates will bind phosphate for a prolonged period until an equilibrium is reached. Dosing nitrifying bacteria during WCs does absolutely nothing. You've already colonized the amount your tank can substain. They do not live in the water column anyways.
