Not able to establish Full cycle - Nitrates problem

[Milea]

Hello,
I have a very heavy stocked mbunas cichlid 80gal tank and I’m trying to create a full cycle filtering (eliminating the nitrates). Actually I’m doing 50% water change 2 times per week to keep the nitrates around 20 (reaching between 40-80 just before the water change). Then for sure...

Hi,
A little backstory:
I set up my 10 gallon aquarium last November, after having thoroughly cleaned it after a major GBA issue. I cleaned everything, even the filter, with tap water, which I recently found out has chloramine, to dissipate any GBA lingering. The only thing I didn't really...

Hi,
Can Pond matrix still colonise anaerobic bacteria inside a high flow filter? My cichlid tank is 250L & it has a Fluval FX6. I’m thinking of replacing my fluval biomax with pond matrix in all the trays but will this make a difference when it comes to anaerobic bacteria?
Thanks...

I have 2-20 gallon tanks. Neither is over stocked and have live plants. I feed once/day. Over the last several months, I have started using RO water for my weekly (to 10 day) water change of about 4 gallons each time. I add Equilibrium...

I have a 90 gallon mixed reef tank that has been setup for almost 2 years and is currently not using any type of chemical filtration other than Phosguard in the sump. I have a skimmer in my sump and a seperate refugium with some mangroves, a deep sand bed and some live rock. My nitrates have always...

I have a 29 gallon tank that is used as a goldfish quarantine tank. We treat the fish for one week with a general internal/external parasite medication. After that the critters are fed to axolotls.
Because we are treating the tank, there is no carbon/chemical based filtration in the tank...since...

Would this allow the Matrix to be in an oxegen deprived environment so as to allow the growth...
