## Questions & Answers

**Q: How much would ou need to use in a 90 litre tank...?**
A: I would say between 1-2 thread in the cap. Each thread works out to 50L.

**Q: Im looking to actually encourage algae growth in my tank, will this help with that?**
A: It depends. With few fast growing plants in the tank then Flourish will tend to encourage algae growth, sometimes very quickly. But it can also unbalance bacterial load in filters if over dosed  so go carefully. You might also find that black hair algae grows quickly ... not always a good source of food for fish, snails or shrimps if that’s what you want algae for.

**Q: Hi. Is this safe to use in newly set up (4weeks) aquarium. Java ferns melting. Thanks**
A: If is newly set up u need tank to go via cycling all plants at first melt before settling in. Keep eye on your tank.
I would not add anything but if you really want should be OK

**Q: If I does 4ml for my 200 litre is that once a wk and is it necessary to  Refrigerate it? Thanks**
A: Depends on how many plants and fish you have, I have a lot of fast growing plants in my 250 litre tank along with slower growers such as anubias, so I add 2ml everyday. Daily is better than dosing 1-2 times per week...Analogy: would you rather be fed 1-2 times per week or daily? 
As for keeping in the fridge: Flourish contains nitrogen, phosphorus, vitamins and amino acids and can get contaminated by stuff in the air when opened which can cause bacteria, mould, or fungus to grow inside the bottle. Seachem recommends putting it in the fridge 3 months after opening, I put it mine in straight away. 

If you start to get a lot of algae growth just cut down on the dosing.
