I have a 75 gallon reef tank and have had it setup for about 2 years now and never had a cleanup crew. I do bi weekly water changes of 20 galons each but during the 2weeks i notice that it gets a little dirty in the way of algae and cyanobacteria. I have heard of this stuff u put in the tank that gets rid of cyano but im not sure if it works... I was thinking of buying a clean up crew for my tank what sort of snails and how many should i get. Ive heard that the numbers that some websites give are way too much. Need some advice.
