prep for new 90 gal... need advice

currently have a 90 gal tank and stand... still piecing the rest together.

need advice on:
lighting - most likely will not get into live plants yet
filter - Eheim Pro 3 electronic (too much?)

cant forget the fish... i will be bringing a tinfoil and a shark catfish (columbian shark) back to the aquarium store... im thinking of doing all smaller fish... but my 8yr old cory cats will be moving into the new tank! they started in a 10 gal then to a 45 and soon a 90... 3 diff cities too btw. need suggestions

If you're planning on corydoras cats, I'd definitely go with a sand substrate. It's good on their barbels plus it's awesome to watch them sift the sand through their gills looking for food. Sand is also a really inexpensive substrate. You can buy play sand from Home Depot for $4-5 for a 50lb bag. Just be sure to rinse it really, really well before putting it in your tank or your water will turn to milk and take forever to clear up.

The lighting doesn't matter much if you aren't going to have live plants but you don't want to overdo it. If I were you, I'd just get a regular fluorescent fixture that's capable of housing bulbs that will allow you to have live plants, otherwise you'll be kicking yourself when you do decide to make the switch from artificial to live (and trust me...spend a few days on this forum and you'll definitely want to).

The Pro III does sound like overkill. For a tank of that size you shouldn't need more than a Pro II 2126. Even that's still $350. You could get a pair of Marineland Magnum 350's and a couple of heaters for a heck of a lot less. Even buying a bigger Fluval or regular Eheim along with some heaters would be a lot less expensive.

Anyway, I'd figure out your source water's pH and hardness, come up with a stocking list keeping those in mind, set up the decor in the tank according to the fish that'll be kept in it, fill, add your heaters and filters and get the tank cycled. Or, if you're moving fish from an established tank, you should be able to just fill it, move whatever decor you have and the filter to the new, filled tank and then just move the fish. You'd want to keep an eye on ammonia and nitrite levels but you should be just fine since your filter should already house enough bacteria to handle the bioload of the fish you've already got.

that great advice! thank you... the one thing i have never done is stock my tank to my water source conditions... reading this post just gave me one of those" DUUUUHHHH why didnt i think of that" moments! makes tons of sense though.

just to keep it going, if i did decide to choose fish that did not fit into my water sources conditions, what would be the best way to make the water sutiable? everything i read on here, people are always against chemicals (which i now understand why) but if not for them, then how?

Well, pretty much a high pH goes hand-in-hand with hard water. If you've got soft, acidic water and you want harder, alkaline water, you can add do stuff like used crushed coral or aragonite sand as your substrate, use limestone rocks as decor, use dolomite or crushed coral as filter media, etc. If you're trying to go the other way around, using peat in your filter can lower the pH and hardness a little bit but won't make much of a difference if your water is very hard. You can also buy an RO (reverse osmosis) machine which removes the ions that make your water hard and in the process moves the pH to neutral to slightly acidic. From there, natural processes in your tank, possibly with the addition of peat, can lower pH more effectively. RO machines are expensive and kind of a pain, so in general I'd say it's much easier to make soft water hard than the other way around.

Though these methods do exist, they are a lot more work and can be rough on your fish, especially if water changes introduce water that's noticeably different from what's in the tank. I definitely think you're better off stocking your tank around your tap water parameters than resorting to the above methods.

I built a 90g just over a month ago and I went with the Eheim P2 thermofilter 2128. I got it on advice from Byron on this forum and I love it. It is a great filter and the temp never moves from +/- 0.2C.

i am replacing a 45 gal tank with this 90 as soon as i finish buying all the pieces... its going to be a community tank. i am absolutly moving my Corydoras... they have been with me through 3 cities and so far 3 different size tanks and about 7-8 years.... they started in a 10 gal, then a 20, now in a 45... its only right they move to the 90!! as far as the tinfoil and the columbian shark.... hmmm well they may go back to the LFS (yes i feel bad, but they keep eating other fish!)... i would like to have mostly barbs... i have, as of this morning 4 baby tiger barbs left...

so now my questions....
currently in the 45 i have gravel, the Corydoras have been living with the gravel their whole life, should i honestly change to sand?
if yes, is home depot play sand (VERY throughly washed) really ok to use?
if i keep only my water and completely replace everything else (ill keep my currently filter going for awhile), will they be OK with the move?

UPDATE: i believe they are Corydoras Aeneus.... they are only silver, no spots or markings...

There are members here who keep corydoras on smooth gravel without issue but the way they filter the sand is really amusing. Plus, I just think sand looks good anyway and is really cheap. I have Home Depot play sand in several of my tanks and have never had a problem with it.
