got a full setup off CL for about 50 bucks so I was completely stoked, and the guy is giving me a fluval 304 canister if he cant sell it by the end of the month 
got a few problems though
1. the tank is DISGUSTING
2. there are more snails in this thing than I have ever seen in my life
3. hair algae or something is completely covering most of the tank
4. came with some corys
Q's
1. the tank has flourite substrate. Is it okay to gravel vac it if its almost the consistency of sand? If a gravel vac would just suck up everything is there anything I can do so I can suck up all the gook in the gravel without taking out substrate in the process
2. what type of fish could I add to help control this. I was thinking a type of African cichlid like an electric yellow, or would a convict work. Or ill add a few small clown loaches. Can be any fish that will outgrow the 30 as long as it can later be moved to my 75 or a 125 I am getting in march
3. is there anything I can do so that this stuff doesnt continue to flourish
4. The guy says he breed his fish. Is it possible to breed corys. They are both same breed but ive noticed the bigger bulkier one is darker, where the smaller one is lighter grey with orange fins. Male and female?
also,
will a zig zag eel eat snails? Ive got a zig zag in it right now.
also also, Ive got 3 tetra 10 gallon rated filters running it right now, will this be fine till I upgrade to the canister or until I get the money for a big penguin filter
thank you in advance
