When I used a typical fluorescent light, I never had diatoms. Since I switched to a T5 light last year, I've been seeing diatoms all the time!

Ammonia (NH3/NH4) -> 0ppm
Nitrite (NO2) -> 0ppm
Nitrate (NO3) -> 25ppm
PH -> 6.5
Drop checker -> Light green


High Nitrate for some reason? what could cause this? its never this high.......im doing 14 gallon waterchanges from now on will that help?



i want this brown alge goon asap

I thought I had high phosphate in my high light, CO2 injected tank that was stuffed with plants but the reason they were high was because the nitrates were low. Perhaps you haven't any phosphate or potassium in the tank?

Since light isn't limiting plant growth, possibly CO2 isn't limiting, definitely nitrate isn't limiting in your tank, that leaves phosphorus, potassium, micros right? Not enough CO2 is always a possibility with bright tanks though.

You should be dosing phosphate already (KH2PO4), and if I remember correctly all your dosing amounts have been posted and checked, so that's probably ok.

The amount of potassium that comes from potassium nitrate (KNO3) and mono potassium phosphate (KH2PO4) is usually sufficient. (Potassium is the K in both those supplements.)

Nitrates may be higher than what you're dosing because fish waste also provides it. Same thing with phosphates. No worries there, extra won't hurt. Continue with normal 50% weekly water changes.

You can get a cheap phosphate test kit if you're curious. But potassium test kits are too expensive to indulge in just for curiosity's sake.

Finally, you've changed enough things at once in your tank that it is, for all intents and purposes, a new tank! I've personally seen "new tank" diatom blooms when changing well-established tanks over from low-tech to high-tech. So this algae isn't unusual unless it persists for more than a week or two.

Clean it if you wish, and otos will definitely grow fat and happy on it. But don't panic, as it's likely just a temporary issue.

you are dosing ei. which basicly means you are dosing more nutirents than your plants can consume especially with your lighting, and your co2 is fine.

YOU ARE DOING EVERY THING FINE!
dont stress. it should pass on its own.
