I decided to take advantage of their free trial just for giggles. 3 weeks in and not much change honestly. Their FAQ does say it can take 3-4 weeks to see results in a planted tank though.
They are very attentive and are helping with every step to get the product working.
I'll post again if the miracle starts to occur
in all fairness they are a relatively new product, but you have to go through this gauntlet with old school aquarium types before they believe you. if nualgae is the real deal they'll make it out of the locker room mostly unscathed,partial type wedgie etc
I got a tank or 4, so figured with a free trial what's to lose?
I've done a couple of other tests with "snake oil" products and while most fail miserably there are a couple that worked exactly as advertised and I now use religiously.
Time will tell what category Nualgi falls into.
I'm now on week 4 of my trial.
I had no algae on the front or rear glass since last weeks water change and dosing. Seems like it might be working.
Now to see if the old "control" algae I left on the glass and some hardscape gets 'starved out' like they claim.
I think it is probably still better to find the right balance of light, CO2, Ferts to prevent algae. But maybe if this stuff works it will make algae free attainable for the masses?
This might be the future solution to algae problem. Why bother with other fixes, if this one works.
Devils advocate here, but why bother with a planted tank if you don't want to learn to get your tank in balance to stave off algae
Just from personal experience, I had a heavily planted dutch for a year and had enough plants to out-compete algae so I never had an issue. Moved the fish to a new tank this year and started a Iwagumi. Big difference since plant mass is much less. I've had to battle GSA and BBA since I started and just now (3 months later) finally found the balance for ferts, light, co2, and o2. BBA is almost non-existent now and GSA isn't growing any longer. Personally, I find it more rewarding to figure it out and watch it go away.
Plus, it doesn't cost me money and make another company richer
I read on their website how it works, and I am not convinced by terms like "outcompete algae" and such. Sounds old school fresh water tank keeping. Maybe that works for salt water, but in the fresh water and planted aquarium realm it is a completely different scenario.
My test is over. I would say it helped keep GSA on the glass grow slower, but didn't eradicate it or any old algae (including control patch).
It may work for some, but I'll go back to figuring out the tank balance with ferts, light and co2.
