Airborne 82nd

If I can not have plants in the main tank would it help or even make sense to grow them in the sump to help with nitrate?

Thanks all good ideas. How do you adjust the flow I have not read about that.

Ok my Fluval 407 came in now I have to think about where to put the intake and output. This is the usual 75gal. 4 ft. tank any ideas are welcomed. My thoughts are end to end with intake half way deep output on the other end up top about 3 inches or so deep angled up. Might get a spray bar to spread things out. If I get a dead spot look into a wave maker. Not sure how much current my Oscar wants as far as the wave maker goes so will need to figure out the size I've only had HOBs before. Also thinking about no fine floss in the 407 and use my tidal 75 center rear with just floss cause it is quick to change. Like I said all thoughts are welcomed. Airborne

I understand about the load. They are all rated with NO load because the manufactuers have no idea what you are going to put inside or how clogged up you will let it get I get that. So if it gets half way stopped up now the intake can only take in half the water it did but some how it can put out more than it takes in. I think I get the max output of 700gph not sure what they are saying about the 450gph circulation and how or if they compare. Thanks for the replies. But I need more some fluid flow type of engineer that can explain it to a dumb old country boy😕 Airborne

The main reason for looking at the 407 is not the tank size as much as the fish. I love Oscars had my last one 12 years but they are pigs😃 I do good at not over feeding but a lot of times it goes right through his gills. Wife says I'm just looking for a way to spend money. Wait till I move the couch out for the 125 Thanks for all replies

Cheap but all you need for what your doing. https://www.amazon.com/Upettools-Submersible-Circulation-Multifunctional-Hydroponics/dp/B07G3Z3NJK/ref=sr_1_6?crid=30D3TVXI2G3IJ&dib=eyJ2IjoiMSJ9.5cg0JE7RySWDcRjtkXwDRnQL9jOgyG0hQbE-XxNDuB09ccvm33GnWajQbsKYrLm-TeeLyLZjiiMCggT2slnrSkzt5DnBHuLpVXJhJmrRxJKzyIMI54qY1O4atNNhXwWUBZ0QxLExIdMnTVIJHWkF2v3KARU8Q9kKXTnz-ThYqmAl5tWzuBI10BBkAgmRwv9xRvWF7g_sNO1XOBkrjpstc6XCbMRE1xEwoGqa0ucIcRE2msjatNhZeL5kyGnXhqZ7l9yUZW_-tdcBrsTec_uhdCbC1iQFJitd9IZ6Ne2smJE.0FcEusI0QFzVPY7Sg3BgqGpzzIQSAGrTqTdhesYjd48&dib_tag=se&keywords=very%2Bsmall%2Bwater%2Bpump&qid=1713747825&sprefix=very%2Bsmall%2Bwater%2Bpump%2Caps%2C2494&sr=8-6&th=1

What if it does leak and he has nice hardwood floors or carpet?

Is there any thing in the female threads now? If yes take that part with you to the store.

Help with fluval numbers on the FX4 it says pump output is 700gph below that it states filter circulation is 450gph. What is the difference? If it pumps out 700 it seems like it would also take in 700 so it would circulate 700. If it pumps out more than it takes in the tank would overflow. I know there is something I'm missing.

My tank is a 75 gallon with two fish 1 Oscar 1 Pleco both about 2 to 3 inches no plants. Now I am using one Seachem tidal 75 I have another one but think I would rather go to a canister instead of two HOB. Trying to decide what size. I've been looking at fluvals 407,fx2 and fx4. What would you choose? Price does not matter Flow wise I think the fx6 would be overkill for a 75 gal. 407=383gph empty fx2=475gph empty fx4=700gph empty. Some say to cut theses numbers in half once full and running a couple of weeks. I would love to hear thoughts on these. How many times would you want to turn this tank over when the fish grow out. They will get a 125 or 150 with fx6 when I sell my rental house. Probably use the 75 as a QT half full.

A few concrete blocks about 6 not sure of the size of a 60 and a sheet of plywood. If you do put it on the ground make sure to check for any rocks or large twigs. Drive way?

First, I have zero idea how much chlorine might be coming into my house through the city water system. Have they flushed pipes? Have they switched from chlorine to chloramine? I want to be sure that I've got enough in the tank to account for fluctuations. This make some sense My understanding is that if you put the prime in the bucket, then put that water to the tank, the prime will bind with the chlorine in the bucket water before anything in the tank has to opportunity to bind with it. So does this I don't know what all prime binds with. I would contact Seachem but think I would just get a lot of sales hype. Sort of like how much there filters flow rate is.

I heard this on the news DON'T

One thing you could do is take a sample of your tank and tap water to a local fish store along with both your test kits they usually have a machine for testing. My store did this for free. My api master kit was the same as theirs my api test stripes ph was way off I put it in the trash. The time on the api master nitrate test is important along with the shake. Here is a good youtube on how to do it.

Sounds like my setup but I went with 200w primary Inkbird on that and a 100 backup. Now after a few days it comes on a couple times a day. 100w never comes on. Airborne
