I was at the LFS
this morning, and a guy there gave me 8 brand new bottles of the Fluval Sea marine supplements for free (worth $100) and asked me to use them and give him feed back after a month.
I took them, but I'm a little hesitant to use them on my system, because it is a delicate system, 10 gallon tank with mixed live and dead rocks, sand, 5 small fishes, and about 9 small to moderate corals.
I love my fishes and trying to keep an eye on the water tests almost twice a week and do periodic top ups.
Do you think it would be a good idea to try those supplements?
