## Description

Seachem Flourish Tabs Growth Supplement - Aquatic Plant Stimulant 40 ct

Review: A Game-Changer for Planted Tanks! - Seachem Flourish Tabs have completely transformed my aquarium! Even though my aquarium is its earliest stage, my plants are thriving like never before, growing lush, vibrant, and healthy. The tabs are easy to use and seem to deliver nutrients exactly as promised. I’ve noticed stronger stems, deeper green leaves, and new growth almost immediately. A must-have for any planted tank enthusiast looking to keep their aquarium flourishing. Highly recommend! Pro Tip: After opening the bag and you have used all the tabs, rinse it with aquarium water and pour that over your submerged plants—this captures the dust from the tabs and gives your plants even more nutrients!
Review: Great For Using In Your Planted Aquariums Substrate - I have been using Seachem Flourish plant tabs in my planted aquarium for the past few years, in conjunction with T-5 linear fluourescent lighting and CO2 injection, and the results have been impressive. Dwarf Hairgrass and Microsword not only carpet quickly, but maintain a lush green color that really highlights these aquaria. I have several planted aquariums and add a few plant tabs to each one - every three or four months or so - after the tabs planted earlier dissolve into the substrate. So it's cheaper for me to purchase these tabs in a larger size box when possible. Seachem's 40 tab box is about three times the price of Seachem's 10 tab box, which means that you get about 10 free plant tabs per box with the larger version. I go through a few of these boxes each year, and consider plant tabs a necessity for planted aquaria that use an inert sand substrate. I also use Seachem Flourish liquid fertilizer once a week in my planted tanks, which works well in conjunction with the plant tabs. However, a word to the wise here. If you are using a high-tech lighting system which also includes injected CO2 and fertilizer supplementation of some kind, you should also consider adding a uv sterilizer to your aquarium to keep the algae and bacteria growth to a minimum. If you don't, you are probably going to find that your water is always going to be cloudy, regardless of how often you do water changes, and whatever filter media you use - including a micron filter. The reason for this is that when one uses these high tech lighting systems with CO2 and fertilizer enhancement, it usually results in far more nutrients being available in an aquarium's water column. This in turn can result in an exponential growth of bacteria, parasites, viruses and other pathogens in the water table, as well as algae, which will cause your water to become cloudy. A bad algae bloom will also result in green water so thick, that the fishkeeper will have a difficult time even seeing their fish or plants. This author has found that the best way to avoid this scenario is to use an ultra violet sterilizer, in order to remove these organisms before they can reproduce. The added benefit in doing so is that your fish will remain healthier, because there will be far fewer pathogens in your aquarium's water table. Moreover, plant growth will improve as well, because your plants will not have to compete for the nutrients in your aquarium's water column, in the way that they would if a larger number of pathogens and algae spores were present. Given that there are many UV sterilizers available for under $100 these days, this is great news for the fishkeeper. In fact, AquaTop (the only aquarium filter manufacturer on the market to do so) sells three different power filters with UV sterilizers built into them (PF-15UV, PF-25UV, PF-40UV), which are capable of uv sterilizing aquariums ranging from 15 to 40 gallons. I own one of each of these UV sterilizer/power filters, for various aquaria, and have found them to work quite well at keeping the water tables in my planted aquariums crystal clear - something I could not say prior to installing them on my tanks. UV sterilizers are no longer just for marine aquariums, since many freshwater fishkeepers are finding tremendous benefits to using them in their planted aquariums. And fortunately, there are now many affordable uv sterilizers on the market, each of which will ensure that your aquarium's water stays crystal clear, and safe for your fish and plants.

## Features

- GROWTH TREATMENT: Seachem Flourish Tabs are growth stimulating tablets for plant roots which contain essential trace elements, amino acids, and vitamins.
- VITAMINS: Seachem Flourish Tabs are rich in iron, manganese, magnesium, calcium, potassium, inositol, choline B12, biotin, and other factors that have been determined to be beneficial to aquatic plant roots.
- NUTRIENTS: When inserted into the gravel, Seachem Flourish Tabs provide direct, time-released fertilization to the plants’ root zone. Nutrients are slowly made available through enzymatic action of the plants’ roots on the tabs.
- TANK USE: Insert one Flourish Tab in the gravel for every 10–15 cm (4–6 in.) radius. A standard 10 gallon aquarium requires 6 tabs. Distribute the tablets evenly throughout the gravel bed, pushing each tablet midway into the gravel bed.
- COMPLETE MAINTENANCE: For optimal plant growth, add new Flourish Tabs to the aquarium once every three to four months. Seachem Flourish Tabs will not alter pH, however, in very soft or unbuffered water, they have slightly acidic properties similar to peat moss.

## Questions & Answers

**Q: What causes this product to kill algae, and does it kill anything else (like beneficial bacteria)?**
A: I bought the Seachem Flourish Excel because it seems to be the best solution to a Black Beard Algae problem I'm having, and after studying what it does, and how it does it, I too was worried about the Beneficial Bacteria in my 2 large canister filters.Couldn't find a direct answer to that question, so I sent an e-mail directly to Seachem Laboratories. Here is my question to them and their reply......
Message: I have a 72 gal heavily planted community tank and am having an outbreak of Black Beard Algae. I purchased your product as it seems the best solution to the problem, but I need a question answered before I can use your product. I now understand how your product works, but will this product also kill off the Beneficial Bacteria inside the Seachem Matrix Bio-Media of my 2 large canister filters?! Crashing the cycle in my tank is not an option. Is this product (Flourish Excel) safe to use for the bacteria that maintains the nitrogen cycle of my tank, or will it kill the bacteria in my filter media along with the Black Beard Algae and crash the nitrogen cycle of my tank? Need a straight answer, please, Thank You

Hi there, thanks for reaching out! 
 No, Excel will not affect your biological filtration if dosed appropriately. 
 Hope this helps! 
Seachem Support 10304
Needless to say, I am very relieved, and pleased. Now I can start the process of getting rid of that Black Beard Algae and not worry about crashing my nitrogen cycle. 2 Thumbs Up to Seachem Laboratories!

**Q: are they copper free?**
A: No. They contain 0.001% copper. Though people have used them in shrimp tanks without a problem, others have had shrimp die, particularly if the tablet got stirred up from the substrate (rescaping, fish burrowing, etc). If there's a chance of your substrate being disturbed, I'd recommend going with API Root Tabs instead, as they do not contain copper.

**Q: How I use this for my tank 20 gallons**
A: Per the instructions:
"On initial use or after a major (> 40%) water change, use 1 capful (5 mL) for every 40 L (10 US gallons). Thereafter use 1 capful for every 200 L (50 US gallons) daily or every other day. For smaller dosing please note that each cap thread is approximately 1 mL."
1 cap = 5ml
1 cap for every 50 gallon equates to 1 ml for every 10 gallons or 2 ml for 20 gallons.

**Q: Is the product compatible with freshwater invertebrates, like amano shrimp?**
A: I use this product on a regular basis and I have snails and shrimp in my tank.  No problems.

### ⭐⭐⭐⭐⭐ Work well.
*by R***R on November 1, 2025*

I've tried many, and prefer these. I think you'll like them too. FYI: Many plants dwindle and die in a few months without CO2. A good quality substrate is essential, but doesn't need to be expensive substrate with time release nutrients.
