## Description

Seachem Flourish 500ml

Review: Amazing for live plant aquariums - Am new to aquariums and learning as I go. Have had my tank for about 3 months now and found advice on how to set it up and keep it healthy very varying depending on whom you were talking to. But after getting my tank set up with water wanted to dress it up a bit before purchasing my fish to start the cycling. Thought live plants would be a great addition and also create a more true bio-system for my aquatic pets once they arrived. But my plants weren't doing well after the first week and found this online in several bulletin boards as the item to get to help them get the nutrients they needed without harming animals I put in my tank. I have a 29 gallon tall tank purchased from a local box store, it came with everything I needed for a basic starting point to improve as I could afford to. I purchased 7 plants one of which died before ordering this product. My levels were out of whack, I check them once a week and as needed to keep track of what worked and what doesn't for me personally. But after using this product for one week noticed new growth, after two weeks the plants that were stressed and turning yellow in color have greened back up. Since have added 5 red eyed tetras and 3 albino cory cats to the tank and everyone is doing well. My numbers are safely within perimeters and it is beginning to look more and more like the tank of my dreams. I did develop a minor issue with black mold but did a total black out for 48 hours and added 5 mystery snails to clean what I missed after physically removing all I could. I also found this locally since then and plan on continuing to use it in future tanks and my current one. Has proven safe for all creatures in my aquarium, makes my plants look and grow very well. Would recommend this to any novice aquarium keeper for a safe and easy solution. I add 1/2 a capful twice a week to my tank near my water filtration outlet to keep it in the water without overdosing the water. From everything I read it stays in the water for 24 hours. I only feed my fish every other day to minimize overfeeding and so far am loving my aquarium and regretting not trying this sooner. My previous experiences with having an aquarium have not done as well as this one. Am glad I kept trying and trusted in quality products to help me overcome any issues that have arisen.
Review: Worked - Took the ick from my fish

## Questions & Answers

**Q: What's the difference between flourish excel and flourish? when should they be used...?**
A: Seachem flourish is a fertilizer, excel is an alternative to co2 injection but can be used with co2. Flourish shoud be dosed at 1ml per tan gallons onec a week. Excel 1ml per ten gallons once a day. And fyi an airstone or bubble wall or surface agitation Will not gas off excel, it will stay in the water for 24 hours and only be used by the plants when exposed to light.

**Q: Would this be safe to use in a 10 gallon tank with Nerite snails and shrimp?**
A: I have a 55 gallon tank with 15 cherry shrimp, I add a capful of this a day and my shrimp are fine. Don’t overdose and slowly incorporate it into your water over time.

**Q: Is it necessary to also buy the flourish nitrogen, iron, etc. for a planted tank? already using this, excel, flourish tabs, and eco complete substrate**
A: Fluorish provides micronutrients, which are certainly important for plant growth. However the macronutrients that Nitrogen, Phosphorus and Potassium provide are the most essential. There is a trace amount of iron in Flourish already, so unless you have plants with Iron deficiencies then you shouldn't need to dose more Iron.If you buy them all in the 500mL bottles, they should last a long time.

**Q: Is this safe for shrimp**
A: I have orange rili and blue vervet shrimp, Cappuccino snails, nerite snails, mystery snails and have had no issue. I have a 40 gallon tank and the dosing is geared for 60 gallons. I cut the dose in half and my plants look great and I didn’t have any algae issues.. more importantly my water babies are alive and happy.
