Chemi-Pure? Carbon? Nothing?

[ronaldvalente]

What does everyone use for chemical filtration?

I have been using Chemi-Pure the last 5 years.
Just wanted to see what everyone else was using.

FWIW I have two Eheim 2217 can's on my 75G tank.

Thanks,
Ron

At most, Purigen. I don't want stuff absorbing my ferts and my water quality is fine without it.

How much purigen do you use in your can?
What size tank?
What filter?

Thanks!

Not bad: Seachem Purigen 500ml $20.67

I do not use a chemical media that removes stuff from the water.

I use peat moss to add organic acids to some tanks.
I use coral sand, oyster shell grit or cuttlebone to add minerals to some tanks.

I keep activated carbon and zeolite on hand in case of emergency, but they have been sitting on the shelf for years.

Carbon: only when removing medication.

Chemipure/Chemipure Elite: never

Purigen: always. I usually run two pillow packs in 2217s and a single pillow in 2213 and smaller.

I was looking at running two 100ml bags one in each can.
According to Seachem directly, I only need a single 100ml bag.
I like to double everything in this hobby.

Yeah the 100ml bags are what you want, remember not to ever let them dry out and they will last for years. To recharge you soak in a bleach/water solution (a day or two with occasional agitation), then soak/agitate in a prime solution, then put right back in the canister.

Carbon is only effective for around 3 days of water flowing through it and is only needed to remove meds or chemical spills.

[somewhatshocked]

If you have two filters, I'd definitely run a bag in each one.

Hello ron...

Save your money and start changing out half the water in the tank every week, no slacking!

Water changes done properly, will take the place of carbon (chemical) medium, because by flushing a lot of pure, treated tap water through the tank, weekly, there's not time for toxins to build up to a harmful level before it's time to remove and replace the water again.

I'll take the frequent water change subject a bit further and say you don't need to go to the expense of overfiltering your tank if you can commit to changing out large amounts of tank water weekly. If you do, then your filter's just filtering water that's already pure.

Pretty simple.

I am a filtration fanatic.
That said I still do 20% changes weekly.

Very good points too.

[somewhatshocked]

Swapping 50% of water every week can be harmful if it's not necessary. Not in all cases, but it's definitely risky and can be confusing for those new to the hobby. Especially with those who keep sensitive shrimp.

Water changes actually can't take the place of a resign like Purigen. Not on the polishing front and not even when it comes to removing tannins from water.

Stick to what you're doing, OP, as you have the right idea and won't regret it. Crystal clear water.

Don't worry, I will never back down from my stance on filtration.

Purigen ordered.

I agree 100% with Jake's above comments.

WCs are good, but for superb water clarification, you can't beat Purigen.
Been using it in my 75 gal planted discus tank 24/7 for years, while still doing minimum 60% wcs twice a week. Tank is always crystal clear - just the way I want it.
I wouldn't be without it.

i'd like to clarify in red. its IMPOSSIBLE to overdo water changes
unless shrimp are involved
no fish, nor plant will ever show any signs of complaint about a good water change
