For ferts I use fluorite scheam. Comp and po4 comp every tuesday and Thursday and po4 every Monday wendsday and Friday

For lights I have a 1 39watts t5 vho bulb at 26" above the substrate with tek 2 reflector

Water is circulating fine and co2 is mix within a reactor before going into the the tank

Well the water near the plants has to be saturated with oxygen. Do you keep a good ripple on the water's surface to keep oxygen level high?

If there is a lot of water circulation then you won't see as many bubbles in the water and fewer on leaves as the water is carrying away the waste oxygen. When I turn off the pumps in the middle of the tank's day the water gets fizzy and there seem to be more pearls on plant leaves but with the pumps on I just see large bubbles coming from the substrate and some pearls on plant leaves.

Some plants pearl more than others too. For me Java fern pearls like mad but Anubias, not so much.

Hi Bryanmc1988,

What is the dKH of the water you used to fill your drop checker?

i dont use co2 or ferts and only common cfl daylight bulbs and even my hornwort pearls and the tips turn pink ill find a pic. so i would say its the lighting either not strong enough, not on long enough, or wrong color range

pearling is accumulation of O2 on the plants.
for that you need a few the water to be saturated with O2, meaning good aeration. you need a good amount of photosynthesis, meaning good light, and high CO2 (and decent flow to get the CO2 to the plants, this is often overlooked), and the plants to be healthy overall.
do a waterchange if you want to see really awesome pearling. that causes my plants to pearl up like crazy, cuz of the O2 supersaturation in the water from the faucet.

well i know i have good circleation of the water and co2 within the tank as the co2 come out of the reactor which is connected to the outle of my canister filter... what i dont have tho is o2 in the water, even with the surface movement i wont see it doing much...



also for some reason the surface of my water is covered in a oil like film, any reason what cause this? i do have some place melting due to just putting them in with out aumalation but there is no feeding as its just plants and no live stocks...

I inject c02 from an inline atomizer leading into a rex grigg style reactor. It turns on 1.5 hours prior to my lights, and I have observed pearling within an hour of the lights being on. Constant ripple on the surface, surface skimmer + lilly ripples. Ferts should always be at optimum levels

What he said....and dont worry about pearling, if plant growth is healthy and no algae issue you are all set.

You turn on the CO2 before lights go on to make sure plants have it immediately?

I just assumed it took them a bit to "wake up" and turned mine on (DIY) after lights go on.

we turn co2 on before light are for one reason is to get max photo period... so that when plants "wake up" they already have it ready for them to use and wont need to wait for it to build up... some plants "wake up" at different time so you never know which one will "wake up" first but this way the plants will have it there when they need it....

also turn off 1-2 hours before lights go out also... for the reason of the plants using up all or most of the remaining co2 before the lights go out....


many people will do this to get max plant growth
