Hau kolas..

I've been battling black beard and hair algae in a 29 gallon planted tank for some time now..and basically losing. I've tried to find fish to control it.. a. splendens, pl*co, CAE all basically ignored it; I've recently added some SAE that at least nibble on it. I've removed affected leaves and plants. I've been unable to find a phosphate test locally, got one through mail-order the other day and the readings from it are off the chart. the test goes from 0 -10 ppm. so, I'm thinking the aquarium must be out of balance to have accumulated such a high level of phosphate and thus the algae. A couple questions..what is the best way to minimize/eliminate/manage the high level of phosphates now; i.e. add more plants (are there certain types which utilize phosphate more readily than others?), chemical media (I'm looking at phosban, any feedback?), something else, or a combination? And hand-in-hand with that, the "best" way to manage for phosphate over the long run? Is there some other nutrient that should be added to enhance phosphate uptake? No CO2, seachem flourish excel instead; trace elements once a week. kH 6 gh 9 pH 7.0 0 ammonia 0 nitrite 5-10ppm nitrates (tap water reads 5 ppm) 65-watt CF lighting 10 hours/day. Tank currently has approx. 20" of fish-load, and an infestation of MTS (I've pulled about 500 out of there over the last 8-9 weeks). Live plants are mixture of root and stem plants medium density. tap water reads approx 0.5ppm phosphate; feeding tetramin pro tropical crisps (analysis chart says 1.1% minimum phosphorous - is this high?) twice daily, fish consume immediately. any suggestions as to what I can do/should do and/or where I've gone wrong greatly appreciated. TIA

Are you adding any chemicals to lower pH? What is the phospate reading
on your tap water?

No, actually using non-phosphate alkaline buffer to keep at 7.0; water tends
to be acidic at about 6.4-6.5 . Forgot to mention that earlier, was actually
coming back to add that info. The phosphate reading out of tap is 0.5ppm.

There are many non-phosphate chemicals to raise pH, such as baking soda. But I
have not seen a pH 7.0 buffer for an aquarium that is _not_ phosphate based. I
suggest that you test some of your buffered fill water with the phosphate test kit
to rule that out.

Hmmm perhaps a clarification..I'm not using a commercial "pH 7.0" buffer;
the buffer in question is seachem alkaline buffer; it states it will
preferentially buffer at 7.8. This is greater than my needs. You can either
add the quantity directed (1 tsp/10 gallons) to get there, or add directed
dosage and then counteract with acid buffer at directed dosage to get your
desired ph. I've found that a dosage smaller than recommended also allows
you to "customize" your pH w/o putting acid back into the system. The
reason for me to use this is my tap water has basically zero buffering; it
reads kH 1 and my pH was a roller coaster. Hence, the benefit to me is not
directly the pH but rather the ability to maintain it at a level which
allows some diversity with what I do with the tank, fish and plant-wise.
I've found that a stable but buffered 7-7.2 serves better than an unstable
but "natural" 6.4-6.6 (has/will crash to abut 6.0 once the buffer is
consumed).

However, I did consider the point of is the buffer REALLY phosphate-"free"?
Tap water reads 0.5ppm; I used 2 gallons and added 1/4 tsp buffer (roughly
the same ratio as what I'm really using going into the tank) and got results
of 1.0 ppm phosphate. I guess I don't know what tolerance is allowed for
something to claim to be "non-phosphate", but it seems the buffer DOES add
phosphate, which if it accumulated, weekly water changes could lead to my
current situation of phosphate of 10+ ppm.

So, you may have found my culprit. I'll change buffers to baking soda (any
'additives' to avoid??) and see what effect this has on this tank.I'll also
see if I can find some phosphate-adsorbing media to try and lower the
existing phosphate along with aggressive water changes. Anything else I can
do to increase existing uptake by plants of the phosphate currently in the
water? TIA

Scott,

Just do a couple of large water changes, that will remove the PO4
buffer.

Now........the algae etc, these are CO2 issues.
If you want a specific pH, use CO2 to do that, otherwise, do not add
any buffer other than baking soda to get the KH to about 3 or so, most
all brands are fine.
If the tap is 3 degrees or higher, you don't need to add any baking
soda.

PO4 of 1-2ppm is ideal for CO2 enriched plant tanks.

Tom Barr

Lila, you have an authoritative response on adjusting pH and KH from the master of
planted aquaria, Tom Barr, and there's nothing more I could add in the way of
advice. In terms of the chemistry, if your buffer was in any way based on
phosphates you would have been off the scale, not just 1.0 ppm. If your
measurement was without error you would have determined that the buffer added 0.5
ppm phosphate. That's reasonable for a chemical additive of this grade. I don't
see how it could accumulate and lead to the 10 ppm reading, so the culprit remains
to be determined.

I am trying to remove phosphate too. Currently, I am using phos-x. After 1 week, I still got 1ppm phosphate. Are there anyone that can recommend a good phosphate remover without damage the plant and fish? BTW, you can buy phosphate test kit to test phosphate. It should be much cheaper than mail order test.

Seachem's Alkline Buffer is phosphate free, although baking soda is much cheaper. In any case, your problem is not the phosphate. You will have to look elsewhere for answers.

Plants themselves need phosphate. In this same thread Tom Barr
recommends 1-2 ppm phosphate. The trick is to have balance in the
nutrient levels. Read Tom's stuff or also read about the Redfield ratio:
http://www.xs4all.nl/~buddendo/aquar...dfield_eng.htm

Fast growing floating plants should suck up phophate and help keep the
level low.

you do have a reply from Mr Barr there, so not much I can add but a
great phosphate remover is Rowaphos. Just keep it in the filter.

I would check the level of phosphate in your tapwater too. You can bring
it down using RO'd water, I tend to use a phosphate remover but because
the PO4 in my tapwater is so high it seems to keep a adequate level of
PO4 in the tank so again its about balance.
