HOWDY HOWDY HOWDY HOWDY!!!
This is AJ's Husband Fishpimpin73 from FIT.N and I am also a MOD over at www.mollyman.com.
Both AWESOME sites and you guys should really come and take a look.
OK, now that the SHAMELESS plugging is over...........
ON TO THE QUESTION
In all reality freshwater CAN BE just as diff as SW, since you already have a SW setup then you understand the amount of time and effort required to have a GREAT TANK.
Freshwater is not that diff when it comes right down to it.
Ever heard of Takashi Amano???
Look him up, he creates the Epitome of FW setups.
When you get right down to it I can honestly say that STARTING a FW tank is a WHOLE LOT easier then setting up a SW tank.
The trouble you run into with FW is maintenance, just as in SW, you have to keep constant watch and test regularly until you begin to have a feel for the things that are going on in your little eco sys.
We have about 17 tanks in our home and they are all FW.
NOW, some of them have been VERY EASY................while others I am STILL struggling with.
ASLO.....
Alot depends on the fish that you are planning to keep.
The SAME rules apply to FW that apply to SW except for the 5g rule.
The gallon rule for FW is A LOT easier to deal with........1" of fish per gallon.
YEAH, I KNOW.......TO BAD SW isn't the same RIGHT???
LOL
The 10g setup you are talking about sounds fine....................except.........
The 330 is prolly gonna be WAY too much for such a little tank unless you have come up with a way to inhibit the flow ( and if you have PLEASE SHARE lol )
Your gonna be MUCH better off with say a pair of AC MINI's or a AC 200, the mini's will be great if flow is NOT a concern, if it is then I would suggest the 200 UNLESS this is NOT going to be a well stocked tank, if not then an AC 150 should suffice.
As far as substrate goes you are gonna want AT LEAST 1 to maybe 2 inches of gravel ( and if you want REALLY GREAT PLANTS look into Fluorite ) bc MOST of the AQ Plants are root feeders and will need the space in the gravel to spread out.
If you are REALLY serious about getting into the PLANTED end of this hobby, run over to www.plantgeek.net and give my buddy OFF-ICE a holler.
He is a GOD when it comes to this planted thing.
PLUS he has AWESOME inventory and GREAT PRICES.
So you can get your plants and all the advice you ever wanted ALL IN THE SAME PLACE
(yeah yeah I know MORE SHAMELESS PLUGGING)
Just let me end this by quoting a good friend of mine DiverJ ( also from FIT.N )
"The keys to any successful aquarium are Research, Patience, and Time"
HTH
