Seachem matrix is also a nitrate remover. Remember when you are relying on bacteria to break down nitrates, it needs to age pretty good before it becomes efficient. An algae scrubber works pretty good too.
So it's been over 4 months since I added Hydroton to all my filters. I have noticed a great improvement in my nitrates. Definitely does seem to make a difference. It's been about 10 days since last water change and nitrates are at very acceptable range compared to before. It does seem to take a while to make a difference very gradual tho not immediate. Thanks for the tips you guys!
Good to hear, I've been using Hydroton too to some of my filters along with Marinepure Cermedia and noticed a leveling off off nitrates, been about 4 months as well. Biohome says for for denitrification it could take from 4 to 6 months to take affect. I've used Seachem Matrix for several years in amounts greater than what they suggested and it never really had any effect.
I use hydrocorn as well in my sump but I also have a wet dry system. For me over filtration is a must but not because of nitrites, nitrates or ammonia. The food waste and poop with so many active fish is endless. I over filter to keep my water clean of floating debris. Africans are so much fun and the more the merrier
Hydroton balls that are well established are for sure the way to go to help control nitrates I use them in all my filters vs the regular media that comes with a filter.
As far as overfiltration goes IMO, filter filter filter is always a good thing. :bigsmile:
As long as the (a) substrate and (b) filter media are thriving with unseen bacteria, filter the water as much as possible. Love to see nice, clean, crisp water to show fish and plants to their best advantage. Remember: This is where the fish live AND poop, so there can be no such thing as "over filtration" as far as I am concerned - given (a) and (b), of course.
I think the main reason we overfilter African Cichlid tanks is to keep the water column clear of debris. If the only thing we were doing is converting Ammonia to Nitrite and then to Nitrate, it wouldn't take as much filtration. Also, it's nice if you can remove some nitrate without water changes, but I think weekly water changes around 50% is quite normal for keeping african cichlids, especially if your tank is heavily stocked.
Regularly removing fish waste from filters and substrate will also help keep nitrates down in the long run. That way all that stuff doesn't have to break down in the tank.
i tend to disagree canister filters are nitrate factories if cleaned often. I clean mine every week or every other week. I had saltwater but you cant compare those 2. Saltwater runs better with a sump. Clean the filter and do water changes. I do run a fx4 on a 75 gallon. so thats a big filter
