Overstocked ?

Hello again,

What do you think of this with better filtration in a 20 long?

What if I had a single AquaClear 50 Power Filter with one mechanical foam filter, some water floss and 2 bio-max bags on top of it all (no carbon)? How often do you think I should change each of those considering my water change ritual of 10 gallons (more than 50%) every 5 to 7 days in a well planted aquarium?

Thanks, I can't believe I may actually be able to pull it off...thumbs2:

I want to have:

18 Cardinals
08 Cory Pygmy
06 Endler males
01 Ghost Shrimp
03 Otos

20 gallon long est. Oct 2009
Flora: 10% Duckweed, Amazon Swords, Java Ferns, Java Moss, Anacharis & Anubias.
Fauna: 18 Cardinals, 8 Pygmy Corys, 6 male Endlers, 3 Otos, & 3 Ghost Shrimp
Filter: AquaClear 50 with foam, fiber, & 2 biomax bags

In a planted tank you only need to rinse the filter pads and media regularly, probably once a month. I never replace the media as its only purpose is to trap particulate matter which you rinse off. And the pads should be replaced when they no longer perform their function which is to force the water through them and not have escape routes.

This plus your excellent partial water change schedule should result in a healthy and beautiful aquarium.

Almost forgot your title question; no, what you list is not overstocking this tank, provided that you stick with your scheduled water changes and it is well planted. Swords are very good plants for this. You might not need the otos with the shrimp who will eat algae and with plants and everything balanced algae shouldn't be an issue anyway.

ACs are awesome choices and I applaud your decision to scrap the carbon and replace with floss & biomax. You hav a lot of cardinals but honestly in a planted, well-filtered tank they shouldn't be an issue.

wait... your sig says 8 cardinals but your stockign is 18?

Thanks Kelly,

Sorry about the signature, it reflects my current stock which I'm trying to improve on...
Here's some pics to show my plant load after some trimming.

That's coming along fine, I like the gravel. You said you're getting more swords, good idea. I think your plants may need some nutrients; are you using any fertilizer(s) now?

Thanks again.

I'm using Flourite Black. There's also Java Moss tied to the rock and artificial driftwood. I will definitely add many Swords. Sadly, no, I've yet to add any fertilizer, I was thinking just recently that perhaps I should add some iron supplement. Is there a favorite of yours?

I asked the question because I thought I saw some nutrient deficiency in the swords. While iron is an important nutrient for swords, so are the other 16 and a deficiency of any one of several can look the same. I do not use iron alone, I did once years ago and the excess iron caused more trouble. Nutrients have to be balanced. My recommendations from experience are Seachem's Flourish Comprehensive Supplement for the Planted Aquarium and Kent Freshwater Supplement. I have used both with success, and these two contain all the necessary nutrients in the required proportion. Once a week to start, after the partial water change. Monitor the plants for 2-3 weeks, and if the swords in particular are not sprouting lush green coloured leaves (the new leaves, the existing leaves will not improve) do a second dose 3 days after the first. I need to do this to maintain my swords and the floating frogbit in the 90g.

In addition, a substrate fertilizer for the swords will result in astounding growth. Flourish tabs are OK, but I prefer Nutrafin's Plant-Gro sticks because they are cheaper, last a year, and after 2 or 3 months the swords that had them doubled in size and new leaves have continued to sprout for months now. I reduced the liquid to once a week at the same time, thinking maybe not necessary, but nope, leaves looked a bit peaked so back to twice a week.

Just for fun, here is a photo I took a few minutes ago of my 115g showing the increased growth since the last photos (under my "Aquariums"). The two Echinodorus bleheri at the back are now up to the surface; the E. macrophyllus on the far left (the sword with long stems and 7-inch floating leaves) is more than 10 years old, and there are two daughter plants from the flower spike it produced this past summer. One is now up to the surface (3 months) and is just right of centre.

I will definitely follow your advice.

Thanks
