Yeah. I think I don't trust snails because I'm a bit uptight when it comes to fish tanks. I like em clean. The worst thing about the nerites may be all the friggin white eggs which never hatch and take forever to disintegrate. Nother thing about tannins is they block more light than you would think, though they may have thereputic, buffering or even antiseptic qualities though. I might use rocks if I weren't afraid of droppin a big one and breaking my tank. Purigen would take the tannins out but might get some trace elements in the process... jury is out on that one.
Yeah I read that about them. That would be pretty gross. My blue Angel loves to "hunt" for the snail eggs in my tank. (I do too...I remove all I can...Before I knew how to properly check plants, I ended up with ramshorn and pond snails in my tank from plants from the LFS) So, perhaps s/he would eat the white eggs. I thought about adding a couple Nerites because they are pretty cool looking.
When I first put big rocks in my tank I used styrofoam as a weight buffer. It worked good. But, it took more rocks than the three I initially planned for to hold it down. Ended up with a rock garden LOL! When I removed them the styrofoam had proven to be a nasty mistake. Beneath it was a ton of dietrist just waiting to float up. Very gross and very shocking. With all the rocks on top of it I never imagined stuff would get under the styrafoam.
Anyway, a few huge rocks fell and hit the bottom of the tank because I was not careful enough to hold the styrafoam down as I removed the rocks. So, 4 rocks slid off when the strafoam bounced to the top of the water. Scared the crap out of me! I thought for sure it was going to crack. Thank goodness the thing is super strong because even with the 2lb, 5lb, 9lb and 10lb rocks (yeah, I weighed them just to see how much weight crashed to the bottom) hitting the glass, it didn't even so much as ding it!
Yeah, I'm with ya about adding "potions" to the tank. Stuff to remove something or stuff to increase things like pH just make me nervous. I know plenty of folks have success using "potions" but I still worry that I won't be so lucky. I love my fish too much to risk it.
On the other hand, the tannins remind me to change water and remind me that the water is constantly being filled with invisible waste too. I am lazy, but water changes are good.
I love water changes! I don't know why honestly, but I really seriously enjoy it.
I was thinking about your tank. I have a few ideas that I would try if I had a bare bottom goldfish tank like you have. Not sure if your looking for suggestions so let me know if your interested
Ya know what though...I am curious why you had trouble with so much waste. When I had goldfish I had more than I should have in the tank (my husband just kept adding them
) They cleaned the gravel constantly. There was also a juvenile spotted sailfin in the tank. The tank was always clear of algae and when I'd vaccuum the gravel once a week, hardly anything would come out of it. And I was aggressive with the vaccuum I tell ya! Perhaps it was because of the soil you used? What about using medium smooth gravel or even the Eco-Complete Planted (I love it!) and try that route? I had the water tested twice a week and always had healthy parameters with o ammonia. This tank is the one I mentioned earlier with the few plants in it.
