What to dose with ??

[Rickybobby]

Hey everyone. Currently I have a 20 cube that is cycled over a month and it's full of macro algae with only one goby. So over the last few weeks the tank is ugly due to barely any nitrates now. The macro is growing like a weed. So what products do you reccomend to dose so that I can creep the levels back up until I figure out what else is going in?

thanks

Just checked with Hanna again. At .3 today a month ago we're 10 so as you can see it need some help and I can only feed that fish so much. It's a sand sifting goby

In the mean time I've taken 16ppm nitrate water from my 2 year old reef tank and swapped a few gallons to add some nitrates

What do you measure nitrate and phosphate to be now?
