Hello Again...I posted in Mid-December about my struggles in fish keeping. As you may have figured from the title they continue. I've update my aquarium profile but to save you some time, I'll include some specs here. Equipment: 10 Gallon Tank (Dimensions: 20Lx10Hx10W) Filter: AquaClear 30 Filter Light: Current Satellite Freshwater LED+ Heater: Cobalt Neo-Thermal 50W (Not in Use) Plants: Amazon Sword (RIP) - Looked good for a month or so and then the leaves started turned translucent in waves. Removed from Tank. 12/15/17 Banana Plant (RIP) - Would never have more than three - four leaves at a time and I didn't like the look. Removed from Tank. 12/15/17 Anubis Barteri - Healthy and attached to a piece of wood. Vallisneria Spiralis Italian - I can't tell. Its shooting out side sprouts but some strands seem to be deteriorating. Moss Ball Two pieces of drift wood Substrate: Sachem Flourite Black Sand. Fish: 3 Tetra Glofish 3 Platy Mix (They poop a ton) 1 Rubberlipped Pleco (RIP - Mid Oct 2017) 1 Paleatus Cory Cat (RIP - Early Nov 2017) 1 Bushynose Pleco 1 Paleatus Cory Cat Timeline: Started Tank 7/10/17 Put fish in tank 7/29/17 (Tetras, Pleco, and Cory Cat) Added Platy 8/5/17 1st Pleco died mid Oct 2017 1st Cory Cat died early Nov 2017 Water Test as of Today PH: 6.0, Ammonia: 0, Nitrite: 0, Nitrate 10 - 20ppm, Phosphate: 5-10ppm Since my last post I have dramatically increased water changes using my tap water. About 3-4 gallons once every 4-5 days (30-40%). Tap Water Info: Water Quality Report for 2016 I also tested the Phosphate today and got 0.5ppm. Even with all of this, I found my Cory Cat upside on Christmas Eve breathing rapidly. I did 40% water changes on back to back days and then another one on New Years and he seems to be better. I've contacted the local fish store and they will take donations. Short of getting a bigger tank which isn't an option right now, I'm 95% sure I have to tank the walk of shame and donate all my fish and start over. The Phosphate from all the fish is just too much to keep up with. Am I right? If I do start over... I'm considering Neon Tetras, Red Cherry Shrimp, Guppies, and a Nerite snail. From the stocking posts I've read these are the fish that I thought could work. Anyone sees any glaring issues with this mix in a 10 Gallon Planted tank? How many of each species? In what order would you introduce them to the tank? Also if I do pull the plug and donate my current fish, what will I need to do to the tank before introducing the new fish? Is donating them as simple as putting them in a ziplock bag and bringing them in? I know I've asked a lot. I truly trying to learn and improve. All help and advice is really appreciated.
