How often wc's im stuck btwn the guys at work. Some say 15% weekly, others say 30% biweekly. Whats best iyo?
Here throw this in as well-
I do 20% every 3 weeks...actually 15 gallons.
I used to do 5g/week which equals the same amount but I have better luck with a larger volume - some would say it doesn't matter.
There really isn't a "golden rule" for water changes - whatever seems to work the best for you!
there are awesome tanks that don't have water changes, some tanks have major changes, you'll find just about every option out there. Newer tanks need more as they establish and it will vary based on feeding, skimming, supplements, bio-load, etc.
I supplement with kalk for top-off that includes vinegar, dose vodka, change water & have fish for the food (poop)...thinking about adding phyto as well.
