Here's three that if you say on a plant board? They will ban you for that. No profanity ,no threats but yes ban you.
1. If you have a planted tank with a light fish load,you might not need to make water changes for weeks,months or more. UKAPS Banned me for saying that despite photos of my aquarium,youtube professionals and 'scaper vids doing what I said.
2. WHY would you pay big money for driftwood and then just cover it totally in plants,mosses? I mean you cant even see the color or grain in the wood any longer. UKAPS and one other board deleted that topic!
3. I posted on The Planted Tank I think it was, a video of the Guppy stream in Austria. Its a 1,000 foot long "stream" that is heated waste water from a coal plant and nothing natural. Its not a natural spring with pupfish that's for sure. So I explained how unique that is...the Mod their banned me "For promoting releasing non natives" what?? There is zero chance guppies and platys will leave that creek and move in with the trout and ice cold water fish that are native.
UKAPS deleted every post I made,but get this ? THEY LIKE THE GUPPYSTREAM POST!"..how ironic one board got hot and bothered over Guppystream and the members of UKAP were fine with that.
Every one of those boards said it was "trolling".hey I been at this 50 years,I just post what I do and then add vids that back it up. Plus,I only have one indoor aquarium so the vids help me make my point.
Dr. Kevin Novak said on one of his newer vids "Post a different view on Aquarium boards and they will beat you up". He said it perfect.
