Is Flourish Excel enough?

Just starting out and figured I would ask instead of waiting to see for myself. Finished converting this tank on Wednesday. Here is my setup

38gal tank
Marineland C-360 canister filter
200W All Glass heater
Coralife Lunar T5 HOhttp://http://coralifeproducts.com/p...ight-fixtures/ 2 10,000k 2 Actinic
40lbs Eco-Complete

Anything that looked cool for plants placed semirandomly
Two mystery snails(atleast till they start eating the plants)
One Tiger Nerite snail
Two bamboo shrimp
Incoming 20 cherry shrimp

Any thoughts or comments on the tank would also be welcomed.

With that much light, you'll need pressurized co2.

Without Algae, death of mankind would be inevitable.

Ok so looking into CO2 systems, I don't really want to make one. Do you have any experience with the little Fluval ones? http://www.fosterandsmithaquatics.co...8&pcatid=22518

Currently they are about 5 inches off the water with no lid.

Raise it a couple of feet till you get CO2 set up. Even then unless you turn off 2 bulbs you still might have algae problems.

Not trying to pile on but I agree with everyone who has posted so far. You are going to need pressurized CO2 and I would not waste my money on the little Fluval system. You would end up needing a new cartridge every week. A full size CO2 rig would be your best investment and give you the best results.

For now definitely turn off the 2 actinic bulbs and either raise the fixture as suggested or put a layer or two of window screen between the lights and the cover to reduce the light. The sooner you can start adding NPK & micro fertilizers plus CO2 the better. It looks like you are off to a good start and it would be a shame to turn the tank into an algae farm. If you can get some Excel double dose it until you have your CO2.

Ok so I turned off the actinic and started looking at CO2 systems some more. I am getting overwhelmed though and can't afford to spend $400+ on these big systems. Can you point out some that I could buy that will work but aren't so expensive? If need be I guess I could attempt to make one of the paintball ones but is that going to be enough?

You can get a new light fixture that would put you in the lower light ranges. Cheapest route I would look into: https://www.plantedtank.net/forums/li...ht-filter.html can't get any cheaper than that IMO. But you're wasting all that electricity in the end.

Currently out of the hobby

or you could hook up a bunch of diy co2 yest bottles... i have 3 hooked up to my 20 long which is running 70 watts over the tank and with excel 2 times a week, i can keep my drop checker a constant green, i had an attack of staghorn and bba, but fixing my nitrates, and phosphates along with my co2 eliminated all algae

If you buy a new (cheap) regulator setup and a 5# CO2 canister, you'll spend a bit under $200. Add to that little things like tubing, check valve, bubble counter, and a diffuser, and you're at or slightly over $200

Ok, you are on the right track but....you still need to reduce the light output from the 2 bulbs that are still on. If I understand correctly that leaves 2 T5HO bulbs still running. That is still too much light without a source of carbon. Raise the light or get some window screen to cut it back (now). Get some Excel (now) and then relax take a breath, and at your leisure look into compressed Co2 systems because now you have a set up that you can control with Excel and NKP + micros. Or don't do those things and see how long it takes for algae to take over. Because it will be a question of "how long" not "if". Just a week or two of full blast T5HO with no supplemental carbon source is plenty long enough to start something ugly.
