Long story short this 80 gallon tank has had lots of "phases". As a newb I couldn't help myself and pretty much planted every type of plant I could get my hands on in it.

I've since pulled mostly everything except my Bucephalandra, anubias, needle leaf java, and a few clumps of blyxa.

I think I want to make this tank an all slow grower tank (low maintenance) but before I do much more I need to do something about the BBA.

It's pretty much everywhere and on everything. Being its practically everywhere I'm considering doing a blackout or full tank treatment using glute but I dont want to hurt my fish. I have a gallon jug of Excel on hand but am afraid of how overdosing it will affect my fish.

I've drastically cut down photo intensity, increased flow, inject C02 24/7 and have manually removing it.

I'm not sure what else to do. Will it eventually just go away on it's own if I've fixed all the things that would make it grow?

- Light 4 Guissman T5's and 2 Kessil A360W
- CO2 controlled by Apex controller griggs reactor
- pH difference between fully de-gassed and fully gassed? 1.2 points
- Current NO3, PO4, GH, KH, pH and TDS readings? N03 10, GH 8dkh, KH 2dkh, TDS 160ish ppm
- What you are dosing (product and quantity) and how often? 2-3x a week Thrive+
- Substrate type and how long has it been in place? Pool sand year+
- What is your filter setup? Wet/dry sump
- Cleaning regimen (filter and water change frequency and amount)? 40% weekly
- Circulation: surface rippling and are all plants gently moving from top to bottom? Vortech MP40 on 10% some slight surface agitation
- What is your water source and do you use a water softener? RODI remineralized using
MgSO4.7H2O(Epsom Salt), CaSO4.2H2O(Calcium sulphate - hydrated)

I add a sprinkle of KHCO3(Potassium bicarbonate)

Any help or advice would be great!

How much Thrive per dose?
How long are the lights on? Schedule?

My first thought was, too much light and not enough ferts. Your 10ppm of nitrate is low.

Also try pushing co2 more. Many go lower than 1.2 drop. Using pH as an indicator of co2 you have to take in to account your starting point. So what may seem like alot may actually not be alot of co2.

Have you thought about using Excel for a bit?

Just my .02 cents [emoji16]

In my experience, most new tanks go through this phase within 8 months due to organics from the substrate (even inert ones like sand).

This is because new packs contain dust, oil, etc which start to decompose when water is first added. This is why people who stick with water changes and cleaning eventually get it under control.

You can see how dirty new substrate is by pouring a fresh pack it into a filled tank. Debris and dirt will cloud up the water.

This is why I always rinse substrate at least 15-20 times before adding it. Even that will not get rid of things which don't belong there and bba will set in for a while (only less).

Gravel vac, 90% water changes and manual removal will help a lot. Also ease up on the ferts if the plants are not showing deficiencies. Good luck!
