Have a Merry Christmas guys!!!

boohhhh !!

Two of my low tech tanks

Great photos! I noticed you have many leaves in the tank. My yard is full of leaves now. How many do you want???

Very nice! I like the natural look of your tank. :emt_thumbs:

Thanks Phoungh.
Pics are from two tanks !

I think you are right. His sump is working very well as far as good bacteria capacity.

Since you mentioned this, my uncle tank is a 75G. He has a 30 gallon sump and Eheim2211.
The tank looks filthy with waste at the bottom. He hardly change water (maybe once a month), but his fish (green terror and some other African peacocks) all look nice and fat. They seem to love that water. Beyond me!!!

Dirt on the bottom doesn't say much about waterquality. As long as good bacteria are there, there won't be any issue.

Only think is waterparameters worsen the wrong bacteria will take their chance and cause infections aso.

Just rule of thump on providing filtration for a tank. Minimum 5:1 turnover ratio.

For example, if you tank is 100 gallon, total flow/hour thru all filters should be about 500 gal/hr.
For 10 gallon tank, I'm using an AC50. The flow rate for an AC50 is 50 gal/hr. :emt_thumbs:

Think my turnover is about 3:1 on all my tanks. I don't think filters are meand to clean the dirt from the bottom (not in my tanks that is) but mostly to clean the water where it comes to nitrogyncycle and fine particles. Syphoning once in the two months I think and they are quite stabil. No diseases aso (fingers crossed).
Btw : spawning isn't always a sign of wellbeing !!! Species will even spawn in the worst conditions just for the survival of the species.

Filterratio with big fish as you guys keep, will definitely be needed higher.

I have seen a lot of dirty tanks but fish keep breeding

African love high flow. YES
Tropheus requires 10:1. No one proves that ratio yet. LOL. but I agree more is better than less.

I would take into consideration the purpose of your filtration.
Clean tank, clean look needs mechanical filter.
Breeding tank, healthy fishes need bio-checmical filter. I have seen a lot of dirty tanks but fish keep breeding.Real plants play an important part as bio-chemical, so no need to add a lot filters.
so its good to have both kinds of filters.

Yes, not all fish can take flow. African love high flow. Tropheus requires 10:1.
For slow swimmer, you can go another route: small flow rate and longer contact time. A sum is a good example of this case.
