Is t5 enought for 2.5 ft depth tank?

[Wst]

Hi anyone can let me know is using t5 enough for 2.5ft depth tank?

tank size 5x2.5x2.5
using quad oddyssea t5ho 6x80w placing at the front and double 2x80 for the back

im trying to grow Monte Carlo carpet but after 2 weeks plant still will turn brown but meantime also new growth will appear.

fert kno3+kh2po4 for mon/wed/fri
lushgro micro tue/thur/sat

co2 5bps

lighting duration 7hrs

Hi any advice?

Your lights seem decent for the tank size and height. Since you are seeing new growth in the MC, it should indicate they are receiving light.

The older emersed leaves turning brown and melting is quite normal as its part of the transition process, but new submersed leaf growth also also be developing fast enough to replace it and start carpeting.

Like mentioned in your other thread, the Co2 injection rate seems rather low for a 5ft tank... have you since gotten a drop checker to check the Co2 levels and their distribution at various parts of the tank yet?

Usually when i see planted tanks that are 4ft or larger, their injection rate (especially at startup phase) is running like crazy, cannot even count the bps, looks like one continuous gas stream inside the bubble counter.

Insufficient or lower Co2 levels in a tank will naturally result in slower plant growth. Ample light and nutrients are only part of the equation, as overall plant growth speed will still be restricted by limited carbon supply.

water circulation and tempearture is also important. I run a 522 and i have 2 x T5HO Quad 80W as well which is 8 tubes in total. The temperature can hit as high as 32 during the photoperiod. Water circulation is important in a big tank as nutrients distribution depends on the water circulation as well.

Like Urban Aquaria mentioned, so long as there are growth then that's a positive sign. For my personal benchmark of new plants i will always look athe top part of the plants to see how the progression, if the top leaves shows no signs of trouble of deficiency then i would leave it to fully grow, i will see an increase of leaves falling off as the weaker leaves die off.

Give it time, and just appreciate your artwork. The biggest pain about planted tank is seeing the outcome of our efforts, sometimes it goes our way sometimes it doesn't
