I agree.. it also depends where you live... some places have high tds levels than others... or if you live near the late jake adams... his tap water is apparently very clean, so he only uses carbon blocks!I’m still new so I’m still learning how to work outside the box lol but a lot of the beginner sources tell us if it isn’t 0 TDS don’t let it anywhere near your tank. So far, I think that may be a little too over the top. Heck some people on here are using unfiltered tap water in their display all the time. Sure, a problem is more likely to arise eventually doing it that way, but I just can’t see a few remnants of unfiltered tap water killing off a tank.
BTW. thanks for the heads up on making sure what my problem actually is... I almost bought vibrant an hour ago to solve the problem... but after you warned me. I started to look deeper into this and found out adding bacteria can cause a chain of reaction that will cause another problem to surface.
hmm... maybe i should do the sand wash or buy a diamond back goby to keep the sand stirred..
Funny thing is... this diatom/dino on my sand only grows and clumps up in shaded areas. maybe my lights are too strong for it to grow on the rocks or sand where the light is blasting? My crocea and milipora seem to love it tho lol!
