I was wondering what kind of nitrate levels either of your mega tanks have and whether it'll be cost-effective putting something like johnptc's nitrate filter onto your tanks. After initial setup costs, it seems all that filter needs are more of that micro c g to feed the bacteria and a pump or two for circulation and water return to the tank. With today's oil prices, heating all that replacement water must put a dent in the pocket. Still lovin' your Wallago
I don't monitor the nitrate. I do a lot of water change per week in all my tanks. A friend of mine did monitor the water several times a few years ago and said it was always low.
John PTC is a super hobbyist and his systems are fantastic.
My fish thrive also but more with low tech approach.
I have many fish that are doing well and more than 15 years in my care. The oldest is 28 years old (not a monster only a 3" clown pleco). Among mini monsters I have a piranha that is 25 years with me. Changing to a different system in my case might not be good for these older fish. Also my water is not the same as what many of you have since we live in different areas.
With the 100 plus tanks and more than 80,000 gallons of water I am inclined to keep the methods I've had success with.
Thanks for your idea. If I have problems in the future I will consider implementing John's system.
I really like the 2 Wallego also. They have that I am bigger than you attitude.
When they zero in for a mackeral or whatever at feeding time.
Everybody else takes off and fast.
