Flourish Excel

Hello everyone, i'm new to planted tanks and to this forum.

i was wondering if anyone has had any luck with Flourish Excel either by itself or as a supplement to regular CO2. i was hoping to use it as the only source of carbon but wasn't sure how well it worked or if it was cost prohibitive.

i plan on setting up a 30 and 20H with about 2 wpg while adding macro and micro nutrients.

No supplements > Flourish Excel > Injected CO2

Some people use Flourish Excel + CO2, but I most tanks with CO2 are just injected with CO2 and no Excel.

On the 20 you could probably get away with it, but even then you would be better off with a DIY CO2 because it would be more cost effective for you. On the 30 I would also do a DIY CO2 or better yet, an injection system.

Injected with a manifold to run both tanks will be less expensive in the long term over Excel. Excel is a great product and can be a very effective algae treatment and preventive.

I run all my tanks on Excel and 2 watts per gallon. I like it as a medium tech, relatively low maintenance system. Very little algae problems, reasonable growth rates and fairly wide choice of plants.

It is kind of a myth that it is expensive to use too. You can buy a 2 liter bottle at Big Al's for 23.99 a bottle. That is 2000 ml. If you dose at the recommended daily dose of 3 ml for a 30 gallon then that bottle will last well over a year. Hardly a huge investment. I can't imagine CO2 is much cheaper than that either.

You can get a $20 Aqualifter pump and then the dosing is automatic too.

Good luck, Bill
