- I have 4 x 23Watts CF DIY over a 25 gallon
- CO2 fertilization is via 2 x DIY CO2 2L bottles
- Substrate is 100% Seachem Flourite

In the tank, I stock
- 1 adult + 2 juvenile platys
- 4 neon tetra
- 1 ghost shrimp
- 3 otocinclus (sp?)

By way of plants, I have:
- 2 asian ambulias
- 1 corckscrew val
- 1 java fern
- 1 banana plant
- 1 parrots feather
- 1 (small) tiger lotus
- 1 anubias nana
- 2 moneywort
- 1 Ludwigia repens
- 1 bunch of dwarf hair grass (spread out in 6 small bunches)

Water Params in tank:
- T = 81 oF
- pH ~ 7.3
- kH ~ 4.0 - 4.5
- gH ~ 3

My filter is a 350 GPH power filter !!! (will be replaced soon).

I do at least 1 x 25% water change a week

I fertilize twice a week with Seachem Flourish.
I find that brush/beard algea get a boost on the Java fern and dwarf
hairgrass leaves everytime I fertilize with Flourish.

I feed the fish twice a day but just enough for a couple of flakes to make
it to the substrate (the rest is consumed at the surface or the way down).

Should I be replacing Flourish with something else?

Honestly, it seems odd to me that you can pull off 3.68WPG with DIY CO2....

Ok, my first guess would be lights, how old, then I'd think maybe the DIY
CO2 is weakening, unless you are religous about swapping them out with new
batches....

What are your nitrAte readings? My 29 got over run with BBA, when I
refilled a CO2 tank, and ran out of PMDD, in just over 3 days, I had things
covered... but it was a total crashing of 3 things, CO2 ran out, 55w pcf
lights were losing intensity, and PMDD ran out.... 3 days later, I was
crying.... heehee

My setup is new (~one month); lights, plants, substrate and all. The tank is
a converted all fish. I have not measured Nitrates or Phosphates in the
tank. I'm still spending the money on tank setup. I figured, however, that I
must be doing something right because the little brush/beard algae on the
fern and the hair grass is the only thing troubling me in the tank right
now. This is, of course, in addition to the fact that I can't get the CO2
levels to 10ppm because of the vigorous mixing/aeration I get from the
350GPH pouring over the tank 24/7.

I hope it is not just beginner's luck.

You can slow down a filter, if it's a HOT filter... pull the uplift tube up
a bit, you'll see a gradual slowing of the flow.... if that's what you
want...

Post some pics of it when you're ready/able... you know where to right?

They, Seachem, appear to claim it doesn't.

Maybe your water changes? Check your tap.

Twice a day, until "a couple of flakes to make it to the
substrate" sounds like overfeeding - unless you have bottom
feeders. Feed once a day, exactly what they will eat -
completely - in 5 minutes.

If you dose Flourish and see noticeable up tick in algae,
then you and your tank may not agree that you're limiting
its growth with phosphate. As I recall, Flourish doesn't
have nitrate either, so you may be limiting on something
else. Plants need a dozen, or so, things. Limiting any of
them will alter growth patterns in various ways.

I use PMDD. I can force my green spot algae two ways.
First, if I does even a tiny amount of P I get a sustained
expansion. Played that fool exactly once - and learned my
lesson. Second, if I massively overdose the PMDD (a 10x
dose) I can force a couple of day spike.

Flourish should be fine. At least they publish their specs.
They have allot of stuff in there that probably doesn't
mean much to your plants, but probably doesn't hurt anything.

I second Red's advice, nitrate may be too low and CO2 is probably
insufficient. What macros do you dose? What are your KH, PH and NO3
levels? May be worth checking PO4 levels too. Chances are one of these
items is limiting plant growth therefore the extra flourish goes
towards feeding the algae. Not convinced on the light issue though, if
they are old tubes then they are putting out less light and probably
helping you avoid even worse problems. Changing the bulb before fixing
any nutrient imbalance may actually make things worse. Besides the
reduction in light output, I have never had algae problems due to
aging bulbs, just a slower growth rate.

Hope that helps
