Hi. Well I got the tank for free.. So that helps me in saving money. As far as equip, I have 2 big filters on the back. I was told I didn't need the power head or skimmer just yet. I have the heater I used for my last 55gal yrs ago. Sand no , but I think I want to do crush coral, so I won't be sucking in sand as far as water changes go. Haven't brought any rock or hydrometer or salt yet..I have 250$ credit at a marine petshop so I could use that at least to buy some items.. How many pieces of live rock do I need? I will buy all my products to set it up on the 1st- so I could get fish by feb1-2014. I like the eels and lion fish can they co-exist ?
HOB filters?
You don't want crushed coral, it becomes a detritus trap and you will see your nitrate level
skyrocket due to this choice
You don't want a hydrometer - they are extremely inaccurate, you do want a refractometer..will set you back about $30
LR from a LFS is extremely expensive and you would get a much better deal buying it on here from another reefer..or you could buy dry rock (at a more reasonable cost) and seed it yourself with 1 piece of live rock. This way you aren't getting rock that is already loaded with phosphates.
For a 55 G - you want approximately 75+ pounds of LR..some rock is more dense than other types, so the weigh of the rock isn't really an accurate measure in figuring out how much to get.
Eels...you need an extremely tight fitting cover to be able to house an eel. Don't even consider one without having a cover first or you will have a dead eel in no time
Lion fish - interesting fish but..they pack a powerful sting..something to consider if you are putting your hands in the tank. They also don't play well with other smaller fish ...
Are you planning on adding coral to the tank?
Do you have a light yet? If so, what kind?
