I have recently replanted a 150 gallon tank and currently I am having a problem with diatoms, I have made some mistakes but my cash supply is limited and I am doing all I can to get set up, my goal is a high tech tank.
Right now I have:
150 gallon tank 48w x 24d x 30tall
5.5 incheches of Flourite Red that is very old
4 x 65w = 260 watts of 6,700 CF = 1.73 wpg
4 x 96w = 384 watts that are off and need new bulbs
5lbs CO2 bottle empty with old Dupla 400 regulator and no reactor
2 x 2215 Eheim canisters with 2217 impellers
So for the time being I have a low tech tank with 1.73 wpg on 11 hrs per day
Fish load is low at 0.39 inches per gallon
Plant load is weak and this is one of my mistakes
1 Aponogeton crispus
12 Cryptocoryne wendtii green
20 Vallisneria asiatica var. biwaensis
9 Cabomba caroliniana
1 Crinum calamistratum
1 Echinodorus Angustifolia "Vesuvius"
15 Dwarf Hairgrass 1 x 1 squares
6 Ludwigia peruensis

I've been doing a lot of reading here and at the Barr Report and anywhere else posts may lead me and have found that Diatoms are a symptom of "low lighting" I thought my light was ok but correct me if I'm wrong. Bad flow is another cause and I think the root of my problem is flow but what can I add to my tank for flow that won't look terrible and doesn't cost too much. The other cause is doing a lot of water changes in a low tech tank, I've read today that water changes add kH and a burst of CO2 and then the plants have to readjust to the low CO2 and this creates the problem and I should be doing only every other month changes.
I have also been dosing PPS Pro weekly but thought it might help to go ahead and dose the PPS rate but every other day alternating macro's and micro's, whats your opinion here.
I have no real way of testing and only have Mardel 5 in 1 strips that are about like guessing, but I can get a feel for nitrites and nitrates, gh & kh seem ok but the ph readings are a waste.
ph I think is 7.0 to 7.6
NO3 0 to 5 and was 20, 30, or 40 before planting
Oh, something I left out is the plants are new (20 days) except the Crypts and Aponogeton which are both putting out new leaves like crazy but after 4 days start to get Diatoms, along with the glass, rocks, wood, and any other slow growing plants. Help with solid opinions.
