Excell And Filtration

Hi--

In an effort to get some plants in the tank while I am struggling with the notion of paying 379.00 for a CO2 system, I recently purchased some Red Cam--it was placed in a 29 gallon tank under 195 watts of light and it being fertilized (to date) with seachem flourish and excell.

Tank is run by 2 HOB (1 marineland and 1 rena with UV)--1 HOB is for mech/biological and the other is for mech/ chemical filtration. Chemical filtration consisters of molecular asbsorption pad (poly bio), a water softener pillow and a chem-zorb pillow. Water changes of approx. 5 gallons a weeks or so

In habitants are neon tetras--several and a few ottos

Now my questions:

1) Will the chem filtration as described above--take out the seachem products, especially the iron?

2) How well will this excell do for the time being under my lighting? To date it looks great--(3 days--and already showing growth)

Please advise and "tanks" in advance for your help

Remove the bio-wheel on the Marineland filter. That will gas off CO2. The chemical filtration is unnecessary.

I don't run any checmical filtration on my 55g anymore. I have an eheim classic 2217? that runs all biological, and an eheim 2213? that runs ALL filter floss. weeky water change of 10 gallons. My water has never been clearer since the floss!

Careful with HOB. Any surface turbulance will cause CO2 loss. a little bit of surface movement isn't bad, but you don't want churning.

I've heard UV is bad for iron, but I use it, and my iron levels are fine (of course I do supplement it) It's something you'll have to play with on your own-I don't know enough about it.

Thanks for the feedback. It comports with what the kid from the LFS said as well. One point, though, I thought that the good thing about excell is that you did not need to worry about gassing off CO2

also, whre does a nice high grade activated carbon come it--can I put this in the Rena before I add more bio cubes and run same for a few days? Or will it take my excell/iron out?

If your tank is well established- I wouldn't use activated carbon. Carbom is a sponge- It absobs a LOT of things- including fertilizers. I have a BIG article on how carbon works. It's not specific to fish tanks, but if you want it PM me and I'll send you a link (I'd have to find it-I have it printed in a book i keep)

195W seems like a lot for a 29 gal to me.

Yeah, almost 7 watts per gallon!

From what I've heard excel will break down with a UV filter. I use a HOB on my planted tank, I just make sure to keep them topped off so there is no surface turbulence.
