But is it going to be as simple as:
1.) Take the fish out
2.) Take out old decorations and gravel
3.) Put in either Flourite or Eco-Complete (after rinsing flourite of course)
4.) Fill tank halfway (with new water?) and put in new plate and decorations.
5.) Let sit for a couple hours
6.) Return fish to their home
7.) Voila! Is it basically that simple?
Is my tank going to have to cycle again cuz that was a real pain!
The brown stuff is probably diatoms, and raising your light level can
As for your switch over -
1. Take the fish out and put them in some of the tank water. I always line a bucket or trash can with a plastic bag, then poof it and close it up just like they do when they bag fish in the store.
2. When you take your old decorations and substrate out, put it in some tank water to keep it moist and retain your bacteria. Same goes for your filter media.
3. Yup, if it's Eco-Complete, you can just dump it in your tank. If it's flourite, you'll want to get that prepared before you start anything else. Here's a good link for step by step instructions - http://www.vickisaquaticplace.com/fluorite.html
This is partly why I prefer the Eco over the Flourite - it's much faster....
4. You can use new water as long as it's almost the same as for pH and hardness. There is no benefit to using the old water for bacteria purposes since it doesn't live in the water column, but on the other surfaces in the tank, and ornaments.
5 & 6. There is no reason to let it sit for a couple of hours. The faster you can get your fish and other things back in, the better. That way there's less worry about your bacteria dying off if it sits too long too. Just be sure to refill the tank with water of the same temp as the fish are in at the time, and dechlorinate it.
7. It's that simple.
If you follow the above steps and be careful not to scrub any surfaces and add your old ornaments and stuff back in, you won't have to worry a bit about a recycle.
BTW, good for you about being careful about overstocking, but you could easily add 3 or 4 more Oto's without being over loaded.
